This refers to a solid-state battery, which differs by using a solid electrolyte instead of a liquid one. Thanks to this design, it is possible to achieve higher energy density and double the driving range compared to lithium-ion batteries of similar size.
In addition, a solid-state battery can charge very quickly — it takes about 10-15 minutes. It also surpasses lithium counterparts in terms of safety, since the risk of fire upon damage is significantly lower.
Serial Toyota electric vehicles with solid-state batteries should appear on the market no later than 2025. The Japanese automaker is already testing prototypes and, together with Mitsui Kinzoku and Sumitomo Chemical, is preparing to launch mass production of such batteries.
It is worth noting that other companies are also developing solid-state batteries. For instance, Volkswagen intends to launch their production in 2025, and Nissan — in 2028.
