With relentless innovation in the electric mobility space, we keep encountering new tech every day to tackle the common issues with EVs.
The technology pertaining to using Silicone anode for EV batteries has been talked about for quite some time now. Admittedly, there have been a handful of new methods being experimented with, to boost the mass adoption of EVs. In a bid to achieve that, the existing ubiquitous challenges need addressing. These include range anxiety, charging times, battery longevity, and abundant availability of charging infrastructure.
The first three things need innovation on the part of carmakers, while the last of these needs cooperation from governments and policymakers. All these aspects need to move together to accomplish the monumental task of transitioning to electric cars. The most prominent and feasible technology in recent times is the use of Silicon anode. Let us glance through the salient features, pros and cons of this technique.

Silicone Anode In EV Batteries
The batteries used in EVs at the moment contain graphite-based anode. Its job is to transfer Lithium ions between the cathode and anode during charging and discharging cycles. However, the issue with graphite is that 90% of the world’s total supply comes from China alone. This includes mining, extracting and refining. Hence, there is too much dependence on a single nation. That is understandably a problem.
Additionally, silicone can hold upto 10 times more Lithium than graphite. Now it doesn’t translate to 10 times more efficiency because there are other factors involved. Still, Silicone will enhance the capabilities of Lithium-ion batteries significantly. Hence, the advantages of using a Silicone anode are evident and direct.

Cons Of Silicone Anode
Even though there are massive pros to using it, there are a few downsides too. Due to a difficult combination of battery pulverization and buildup of wasteful byproducts, the carmakers can only integrate 5-10% silicone into anodes. During the process of constant expansion and contraction, the EV battery’s solid-electrolyte-interphase (SEI) layer becomes brittle and causes it to decay at a faster rate. Hence, the life cycle of the battery is reduced.

Lithium-ion batteries, featuring anodes infused with silicon nanoparticles, effectively alleviate the primary concerns that consumers have regarding the adoption of electric vehicles. These batteries extend the vehicle’s range significantly on a single charge, enable faster charging times, and boast a longer lifespan compared to the prevailing industry norm.
This means that ordinary consumers can enjoy extended travel distances, faster recharge rates, and prolonged battery life, thus avoiding the inconvenience and expense of frequent battery replacements every few years. Let us see if this technology achieves large-scale commercialization to become the norm in times to come.
