Failure Rate of Modern EV Batteries is 0.1% – Study

An interesting study showcases how the EV battery failure rates have declined from 2011 to 2023. The health startup Recurrent published a study which encompasses the failure rate of modern EV batteries. This study was titled New Study: How Long Do Electric Car Batteries Last? The findings of this study were documented in a report by the U.S. Department of Energy’s Vehicle Technologies Office. This survey took data from around 15,000 rechargeable vehicles between 2011 and 2023. The outcome was quite surprising.

While there is still a long way to go, we are at a lot better and technologically advanced stage today, in comparison. Hence, the EV battery failure rate was a whopping 7.5% in 2011 and 1.6% in 2015. These stats don’t include the recalls. Things changed for the better post-2016. Advanced technologies like active liquid battery cooling, more sophisticated thermal management systems and new battery chemistries have emerged. That becomes visible from the battery failure rate in 2016, which was just 0.3%. Furthermore, this number went even lower to 0.1% in 2017. Hence, one could think of the time post-2016 as the second life for EV battery technology. The stats have danced around 0.1% to 0.5% from 2016 to 2023. This translates to – 1 in every 1,000 EV batteries could encounter failure. That is quite a healthy rate. However, it must be pondered whether the EV industry becomes successful in bringing this down even more by 2030 with the intense R&D work going on in battery tech and EV battery cell chemistry.

We must also mention that data will become more readily available as the existing EVs age and electric cars become mainstream in the next few years.

Stellantis CEO Aims To Cut EV Battery Weight By Half

Battery / By LEC Team

The size and weight of EV batteries have been a topic of debate and contention since the inception of electric cars. Stellantis CEO, Carlos Tavares, wishes to reduce the weight of the EV battery packs by half over the next decade. Now, we know that the EV battery constitutes a major chunk of the overall mass of a vehicle. In EVs, the entire bottom part of the car comprises of the battery. In fact, in some formations like cell-to-body, the top layer of the cell container forms the floor of the EV. The higher the number of cells in an EV battery, the higher its range. But so is the weight of the vehicle. You might also like: Top 3 Potential Alternatives To Lithium-Ion Batteries For EVs Stellantis CEO Aims To Cut EV Battery Weight At the recent Stellantis Freedom of Mobility Forum, Carlos Tavares expressed his concerns regarding the excessive weight of EV batteries. He said, “From an environmental standpoint … I don’t think it makes sense [to have such heavy battery packs]. I think over the next decade we’ll be able to reduce the battery pack weight by 50%, hence reducing by 50% the use of additional raw materials against a conventional vehicle.” This conversation was a part of his interview with Reuters. Furthermore, he added that the existing EV batteries with a range of around 250 miles (400 km) need approximately 500 kg (~1,100 lbs) of additional raw materials over conventional ICE cars. That is an alarming figure with regard to the environment. With the ongoing R&D in the EV battery technology, the batteries will become more efficient which will, in turn, reduce the weight to offer a similar range. Stellantis’ EV Plans Interestingly, the Stellantis CEO didn’t mention any specific way to reduce the weight of the battery by half. Still, it hopes that 100% of sales in Europe will be for all-electric vehicles by 2030. By this time, the conglomerate also estimates that 50% of its sales in the USA will be for BEVs. To put this into concrete numbers, Stellantis aims to sell 5 million BEVs annually by 2030. To achieve this ambitious target, it will have introduced more than 75 BEVs by 2030. These EVs will make use of 4 vehicle platforms under the SLTA architecture – Small, Medium, Large and Frame. The latter will be a body-on-frame platform for hardcore electric off-roading SUVs. Moreover, it will incorporate 3 drive modules, 2 battery cell chemistries, front-, rear-, and all-wheel drive configurations. Its electric cars will possess a range between 500 km and 800 km (300 miles to 500 miles). Hence, depending on the market and customer preferences, Stellantis will have all sorts of combinations to cater to the demands.

1 Comment / Battery / By LEC Team

The two companies have signed an agreement toward the supply of cylindrical automotive Li-ion batteries. Mazda and Panasonic Energy entered into an agreement to supply EV batteries consisting of cylindrical cells. In June 2023, the two companies commenced discussions toward building a medium-to-long-term partnership for the supply of cylindrical automotive lithium-ion batteries. More details about the exact route they will adopt, timeframe, investment, etc., will be announced later. For now, let us take a look at the salient features of cylindrical cells in EV batteries. You might also like: Top 3 Potential Alternatives To Lithium-Ion Batteries For EVs Cylindrical Cells in EV Batteries There are primarily three types of cells which find application in the automotive world – Prismatic, Cylindrical and Pouch. In recent years, the former two have found the widest application. Prismatic Cell A prismatic cell refers to a cell with its chemistry contained within a rigid casing. Its rectangular shape allows for efficient stacking of multiple units in a battery module. Prismatic cells come in two types – those with electrode sheets (anode, separator, cathode) stacked within the casing, and those with the electrode sheets rolled and flattened. In terms of performance, stacked prismatic cells, for the same volume, can release more energy at once, providing superior performance. On the other hand, flattened prismatic cells contain more energy, offering increased durability. Primarily utilized in energy storage systems and electric vehicles, prismatic cells are less suitable for smaller devices like e-bikes and cellphones due to their larger size. Hence, they are better suited for applications requiring higher energy consumption. You might also like: Lithium-Sulphur Batteries For EVs Promise 5-Min Charging Time Cylindrical Cell A cylindrical cell refers to a cell enclosed within a rigid cylinder casing. These cells are characterized by their small, round shape, allowing them to be stacked in devices of varying sizes. Unlike other battery formats, the cylindrical shape of these cells prevents swelling, a phenomenon where gases accumulate within the casing. Initially, cylindrical cells found application in laptops, typically comprising between three and nine cells. Their popularity surged when Tesla incorporated them into its earliest electric vehicles, such as the Roadster and the Model S, which housed between 6,000 and 9,000 cells. The famed 4680 is a type of cylindrical battery. You might also like: New CATL Batteries To Retain 80% Capacity After 12 Years Learn Electric Cars Says While it is difficult to set a standard in the diversified electric mobility industry just yet, it looks like the cylindrical and prismatic cells could be the long-term solutions. In fact, more battery companies are increasingly exploring the advantages associated with cylindrical cells lately. In addition to Panasonic, even the Korean battery giant, LG Energy Solution is working on 4680 cells and the production will commence at its Ochang plant in South Korea in August 2024. Even though it might be too early to call, the cylindrical cells in EV batteries seem to be winning the race at the moment.

Alternatives to Lithium-Ion EV Batteries

Top 3 Potential Alternatives To Lithium-Ion Batteries For EVs

2 Comments / Battery / By LEC Team

In a world where new EV battery tech is being developed almost every other day, it seems like Lithium-ion chemistry might not be the only way forward. As the R&D in EV battery technology progresses, we might soon get acquainted with the alternatives to Lithium-ion batteries for EVs. In fact, in small volumes, there are already some of these alternatives being used. However, to have either of these on a commercially large scale is still distant. In any case, this opens up new avenues to explore to tackle the shortcomings of Lithium-ion batteries. You might also like: New CATL Batteries To Retain 80% Capacity After 12 Years Alternatives To Lithium-Ion Batteries For EVs Carmakers have been using Lithium-ion batteries in EVs on a large scale for a good part of a decade now. Its advantages include high energy density, decent safety, great affordability, long battery lifespan, power, etc. In fact, a typical Li-ion battery has an energy density of 150-220 Wh/kg. But its cons will come to the surface in times to come. This includes dependence on rare earth minerals like Nickel, Manganese and Cobalt (NMC), water and resource-intensive mining processes and complexity during recycling. Hence, researchers are looking for alternatives. Among others, the most promising options are the following: Sodium-Ion Batteries One of the most promising types of chemistry which could replace Li-ion is Sodium-ion. There are specific reasons for this. In contrast to Lithium which only has limited reserves and the mining process is resource-intensive, Sodium is one of the most abundant elements in the earth’s crust. To put things into perspective, the Sodium-to-Lithium ratio in Earth’s crust is 23,600 parts per million (ppm) to 20 ppm. Even the cost of extraction is substantially lower. Manufacturing-wise, these batteries can be produced at the same facilities and production lines as the existing Li-ion batteries. Hence, the scalability can be rapid. Moreover, Sodium possesses the ability to be stored and transported at zero volts. This results in massive safety promises. It is also low flammable, further enhancing its safety aspects. One of the downsides, however, is the low energy density – 140-160 Wh/kg. This reduces the range of EVs, which is a big obstacle in its mass adoption. Secondly, a typical Li-ion battery has a lifespan of around 8,000-10,000 charging cycles. But Sodium-ion batteries are only able to achieve around 5,000. Nevertheless, research is going on to tackle these issues in various parts of the world. You might also like: Next-Gen EV Batteries From Korean Giants Unveiled At InterBattery 2024 Solid State Batteries Solid-state batteries offer several advantages over traditional batteries. By using solid electrolytes, they mitigate the risk of dendrite formation, enhancing battery longevity. Furthermore, their reduced flammability improves safety, while their higher energy density and faster charging cycles provide superior performance. However, challenges exist, including scalability issues compared to sodium batteries, which are lower in cost and easier to integrate into existing production infrastructure. Manufacturing costs for solid-state batteries are presently higher than lithium-ion batteries, hindering widespread adoption. To propel solid battery technology, durable solid-state electrolytes must be developed, although the ideal electrolyte remains elusive. Nonetheless, companies like Solid Power are making strides, boasting a sulfide electrolyte-based battery with significantly higher energy density than lithium-ion alternatives. Solid Power aims to power 800,000 electric vehicles annually by 2028 with its solid-state technology. While solid-state batteries are commercially available for small-scale applications like wearable electronics, IoT devices, and medical implants, they are not yet suitable for large-scale energy storage. Shirley Meng emphasizes the need for realism, asserting that while viable for IoT and wearables, solid-state batteries must scale to produce terawatt hours of energy to truly impact the energy transition. You might also like: Are EVs With 1000 km Range Still A Distant Reality? Lithium-Sulphur Batteries As the name suggests, these batteries still use some Lithium. But because Sulphur is used instead of NMC, it is more abundantly available in the earth’s core and is less resource-intensive to extract. Apart from that, Sulphur is also a by-product of natural gas processing and oil refining. Till the time this process continues, there won’t be any shortage of Sulphur. The resemblance with Li-ion batteries ensures that their production is easy and scalable using the same manufacturing plants and processes. These are also considerably more energy-dense in comparison to regular Li-ion batteries. On the other end of the spectrum, there are some peculiar disadvantages which prevent commercialization at the moment. These include poor chargeability which leads to the formation of tree-like structures called dendrites. They can cause short circuits and battery failure. Also, the prototypes have just been able to work for 50 charge cycles, rendering them useless to power EVs. Interestingly, Lithium-Sulphur batteries already exist in the mass market in products like electronic gadgets and wearables. You might also like: Nyobolt Battery Can Charge Fully In Just 6 Minutes Learn Electric Cars Says The EV revolution has reached an intriguing point in its journey. In developed markets like the USA and China, the demand has slowed down. On the other hand, there are still some prominent markets where the transition is still at a much nascent stage but the demand and sales are exponential. These would be countries like India, Brazil, Thailand, Singapore, etc. In the meantime, there are new breakthroughs in EV battery technology on a daily basis. This constant development is not going to stop anytime soon. Therefore, at this point, we can infer that there will probably be no single silver bullet. Multiple batteries and technologies would co-exist depending on the use cases. That’s why it is prudent to learn about all the new EV battery types that have a shot of making it to the mass market as alternatives to Lithium-ion batteries for EVs.

Another day, another potentially ground-breaking EV battery technology! According to a research paper published in Nature Nanotechnology by University of Adelaide researchers, the next-gen Lithium-Sulphur batteries for EVs can be charged in less than 5 minutes. In this type of battery construction, Sulphur cathodes are used due to high energy density and Sulphur’s abundant availability. It can find applications in electronic devices including electric vehicles, as well as power grids. You might also like: New CATL Batteries To Retain 80% Capacity After 12 Years Lithium-Sulphur Batteries For EVs The research paper confirms that the energy density of Lithium-Sulphur batteries is around 550 Wh/kg. This is more than twice what the existing Lithium-ion batteries offer (around 150-200 Wh/kg). Hence, the range of EVs could benefit from using this type of battery exponentially. Note that high-powered Lithium-Sulphur batteries are already being used in mobile phones, laptops and electric vehicles. However, the biggest challenge is the charge-discharge time. It could range anywhere between 1 hour and 10 hours. This is where the breakthrough has been achieved. The researchers analysed the Sulphur reduction reaction which dictates the charge-discharge rate of Lithium-Sulphur batteries. They investigated various carbon-based transition metal electrocatalysts, including iron, cobalt, nickel, copper and zinc during the SRR. The team designed a nanocomposite electrocatalyst made up of clusters of carbon material and cobalt-zinc (CoZn). Senior Author Professor Qiao said, “When the electrocatalyst CoZn is used in lithium-sulphur batteries, the resulting battery achieves an exceptional power-to-weight ratio. Our research shows a significant advancement, enabling lithium-sulphur batteries to achieve full charge-discharge in less than 5 minutes.” This study aims to tackle the problem of these batteries’ slow charge-discharge rates for the first time ever.

New CATL Batteries To Retain 80% Capacity After 12 Years

3 Comments / Battery / By LEC Team

Chinese battery giant CATL and NIO have collaborated to work on new technology that will allow EV batteries to still possess 80% of capacity after 12 years of usage. As per the latest partnership with NIO and CATL, new batteries are being developed with substantially longer lifespans than the existing ones. Battery forms the single most expensive component of an electric car. In most cases, this is around 40% of the total cost of an EV. Moreover, Lithium-ion batteries have a tendency to lose capacity after usage. Hence, most carmakers offer a warranty of around 8 years. Thereafter, the battery replacement costs become a huge issue for EV owners. In order to ensure that the batteries last at least as long as the car (or approximately 10-12 years), Chinese battery giant CATL and NIO have established a partnership. They will co-develop a battery which will be able to retain 80% of its capacity even after 12 years of application. You might also like: EVs To Be Cheaper To Produce Than Gas Cars By 2027 – Study New EV Batteries From CATL and NIO NIO has created a pioneering system for keeping electric car batteries healthy. This system looks after three key factors that affect how long batteries last – temperature, how hard they’re used, and how often they’re charged. By using clever technology and a special way of swapping batteries, NIO has made sure these batteries can last a long time. Thanks to smart planning based on lots of data, NIO’s batteries can keep about 80% of their power even after being used for 12 years. Plus, NIO has worked hard to make batteries that last longer. They’ve studied the materials that make up batteries, like the stuff inside the battery that helps it work, and the liquid it’s filled with. This research has led to better batteries. NIO has become really good at all stages of creating batteries, from making the materials to testing them out. They’ve even got over a thousand patents for their technology. More than a hundred of them focus on making batteries last longer. You might also like: Next-Gen EV Batteries From Korean Giants Unveiled At InterBattery 2024 New Technology By CATL CATL and NIO also believe that between 2025 and 2030, there will be around 20 million electric vehicles which will come out of the warranty period. This doesn’t necessarily mean that the vehicles won’t be in an unusable condition. But the owners will have to shell out a bomb to replace the batteries. To tackle, that CATL has been working on innovative methods to prolong the lifecycle of EV batteries to upto 12-15 years. CATL has created new technology to make battery packs last longer. They’ve invented things like a special Solid Electrolyte Interphase film that can fix itself and add more lithium to batteries. By working together, the companies aim to build a partnership that benefits them both in the long run. These batteries will complement NIO’s battery-swapping business immensely.

5 Helpful Tips To Maximize EV Range In Winter And Snow

1 Comment / Featured / By LEC Team

Driving EVs in snowy winters can be immensely challenging. Therefore, it is great to know a few tricks and tips to ensure minimal impact of the cold on your EVs. In this blog post, we shall offer 5 crucial tips to maximize your EV range during winter and snow. Driving an EV can be worrisome anyway due to the lack of adequate charging infrastructure and range anxiety. However, things exacerbate further during the peak winter season when the temperatures drop significantly below 0 degrees Celsius. Unfortunately, all Lithium-ion batteries are sensitive to extreme temperatures. You would’ve noticed this with your smartphones and laptops too. As a result, EVs tend to offer considerably lower range on a single charge during adverse weather conditions. Still, there are a few measures that EV owners could adopt in order to minimize the impact of snow or extremely low temperatures on their EVs. You might also like: Study Shows EVs Can Be More Cost-Effective Than ICE Cars In Some Locations 5 Tips To Maximize EV Range In Winter & Snow Preheat Battery One of the most effective methods to tackle the issue of low range during winter conditions is to pre-heat the battery. Some modern cars come with a heat pump which ensures that the temperature of the battery remains in an optimal range. Also, while the electric car is plugged in, the battery of the car gets in a perfect temperature range even before the owner commences the drive. In that way, the battery won’t draw additional power to do this task of maintaining its optimal temperature. AC Temperature Yet another way to reduce the power consumption of the EV battery during harsh cold is to use the heat produced by the car to warm the cabin. Most people crank up the blower to the maximum in order to heat the cabin space. However, a slightly more nuanced and prudent technique is to use heated seats and steering wheel to keep yourself warm. That will consume much less power from the battery, in turn maximizing the range. Obviously, your EV needs to have this function from the factory. You might also like: 1,300 hp BYD YANGWANG U9 Is Ready To Redefine Electric Supercar Segment Tires A significantly underrated aspect while calculating the range of EVs is the tires. In fact, we feel that car owners don’t pay enough attention to tires in general. In the case of snow or harsh winter conditions, generally, the tire pressure drops. That leads to a situation where higher power is needed to move the car. Hence, more battery is consumed in the process. Therefore, you must ensure that the tire pressure in your car is appropriate at all times. Also, it helps to use dedicated snow tires. Speed Unlike ICE cars where high speed means high engine efficiency, the range of EVs deteriorates exponentially as the speed increases. This is due to higher wind resistance and drag coefficient. The battery gets depleted at a higher rate at high vehicle speeds. Therefore, driving at moderate speeds can boost the overall range of EVs substantially on a single charge. Eco Mode Finally, if your EV comes with drive modes, it is advisable to use Eco mode to maximize range. In peak winters or snowy conditions, you wouldn’t want exquisite performance and high-speed scenarios with your EVs anyway. Therefore, switching to Eco mode will limit the power produced by an EV, in turn, saving the battery from getting empty quickly. Hence, it is a great way to use the drive modes in an EV. You might also like: EV Makers Reconsidering Their Ambitious Plans, Was Toyota Right All Along? Learn Electric Cars Says Extremely low temperatures slow down the reaction inside an EV battery. That is the reason why charging EVs becomes extremely slow, while the battery loses range rapidly. There are many parts of the world where the temperatures get way below 0 degrees Celsius. Arguably, the most prominent market is Norway where around 82% of total EV sales in 2023 were electric cars. Norway experiences one of the harshest winters in the world. Still, due to the aforementioned practices, they are able to navigate their way to ensure that using EVs remains practical and feasible. Hence, it is possible to use EVs effectively even in harsh winters with proper planning.

With innovative and rapid development in EV battery technology, EVs with around 1000 km of range look promising and enticing. However, many naysayers argue that you don’t need EVs with such high range due to the battery weight and size concerns. Also, large batteries would require more time to charge. That will add to the already bleak charging infrastructure. But what if there are ways of just increasing the range of EVs without increasing their battery size? You might also like: Nyobolt Battery Can Charge Fully In Just 6 Minutes EVs With 1000 km Range Possible? Scientists at Pohang University of Science and Technology (POSTECH) in South Korea have developed a new technology. It involves using micro-silicon particles and a gel-based electrolyte to enhance the ability of lithium-ion batteries to retain charge for longer periods. Now we know that researchers have been working on silicon to replace graphite for the higher charge capacity of the batteries for a while now. However, the property of nano-scale silicon to expand while charging and discharging has been its typical limitation. To address that, the POSTECH scientists have come up with micro-scale silicon. This, in conjunction with an elastic gel electrolyte, will solve that problem. Inherently, silicon can hold 10 times more lithium ions than graphite. That lends a high battery capacity, in turn increasing the range significantly. Additionally, it prevents the rapid degradation of the battery. In fact, scientists noted that the micro-silicon particles allow a range of 965 km on a single charge. Soojin Park co-authored the research paper and is a professor of Chemistry at POSTECH. He said, “We used a micro-silicone anode, yet we have a stable battery. This research brings us closer to a real high-energy-density lithium-ion battery system.” However, the production process of such micro-scale silicon anodes will be much more complex and expensive.
