Samsung Showcases Solid State Battery For EVs With 1,000 km Range

The South Korean conglomerate is among the biggest players to perform R&D to create batteries for future EVs.

At the SNE Battery Day 2024 Expo, Samsung unveiled its Solid State Battery for EVs which can offer a range of up to 1,000 km (621 miles). This EV-specific solid-state oxide battery also promises reduced charging times and eliminates the risk of battery fires. The Korean electronics giant aims to commence production by 2027. One of the notable car marques which might use this is Toyota in its luxurious Lexus electric cars.

What Are Solid State Batteries?

If you are even remotely associated with electric car technology and industry, I feel you must’ve heard about Solid State Batteries. These are among the most promising emerging technologies to power the future EVs. These use solid electrolytes which remove the risk of dendrite formation. It leads to the enhancement of the longevity of the battery. In addition, their reduced flammability improves safety, while their higher energy density and faster charging cycles provide superior performance.

Samsung Showcases Solid State Battery For EVs

Many top carmakers have been testing the samples. While the official information about these specific car companies is not available, Samsung has worked with Hyundai, Stellantis and General Motors. Translating a report by The Elec, Samsung SDI Koh Joo-young said, “We supplied samples to customers from the end of last year to the beginning of this year and are receiving positive feedback.”

He added, “All-solid-state batteries can increase safety by changing liquid to solid, and when made into the same pack (as existing products), the weight is reduced and the space taken up is smaller, which can lead to a cost reduction in the vehicle itself, so automakers are interested in them.” These highlight the appeal of this technology which seems like the way forward.

Needless to mention, the cost will be a huge concern. Consequently, premium EVs will be the first users of these batteries. The relevance of the retail price is slightly lower on that end of the spectrum. Apart from that, Samsung even discussed its plans of creating EV batteries which can charge in 9 minutes and last 20 years by 2029. The Solid State Battery from Samsung will have an energy density of around 500 Wh/kg. This is nearly twice that of the regular Li-ion batteries available with EVs today.

The catch is that these batteries will need an ultra-fast charging network. Note that these are not your regular DC ultra-fast charging stations. In fact, there are just a handful of such charging stations in China which offer speeds upwards of 480 kW and even reach 600 kW. That has to be the standard if the dream of making solid state batteries has to be converted into reality.
