Samsung's oxide solid-state batteries, currently in pilot production and testing with automakers, are creating significant excitement in the electric vehicle (EV) industry. These next-generation batteries boast an energy density of around 500 Wh/kg, which is nearly double the capacity of today's mainstream EV batteries. The Elec reports that these batteries can fully charge in just nine minutes and have a lifespan of up to 20 years, making them a game-changer in terms of performance and longevity.
According to Samsung SDI Vice President Ko Joo-young, automakers are highly interested in these batteries due to their smaller size, lighter weight, and enhanced safety compared to current EV batteries. However, the high production costs mean that, at least initially, these batteries will be limited to the "super-premium" segment of electric vehicles. Luxury EVs equipped with Samsung's solid-state batteries could travel between 900 and 1,000 kilometers (over 600 miles) on a single charge without significantly increasing battery size or weight.
Toyota is also aiming to mass-produce solid-state batteries by 2027, though the company has indicated that its first deployment will likely be in premium Lexus EVs. Despite these advancements, Samsung and Toyota are still playing catch-up with Chinese battery manufacturers, particularly CATL, which remains the leader in the EV battery market. CATL anticipates a one-percent penetration rate for solid-state batteries by 2027, indicating the competitive landscape of this emerging technology.
