The charge storage density in them is increased by 40%.
At the InterBattery exhibition in Seoul, as reported by Nikkei Asian Review, local company Samsung SDI announced its intentions to begin mass production of batteries with solid-state electrolyte from 2027. They will find application not only in electric vehicles, but also in various technologies, and their main advantage will be a 40% increase in the specific charge storage density in volumetric terms. In fact, one liter of battery capacity can save up to 900 Wh of electricity.

In addition to lighter weight and higher capacity, solid-state batteries in electric vehicles will reduce the risk of fire, better withstand extreme temperatures and replenish their charge faster. An experimental line in South Korea for the production of such Samsung SDI batteries has already begun its work, product samples are being supplied to potential customers, among whom BMW is mentioned. Hyundai and Toyota also expect to offer electric vehicles using solid-state batteries by 2027.
