|Solid-state batteries promise to prove safer and longer lasting than conventional batteries. Now companies suggest they may commercialize solid-state batteries in the next five years for use in electric “hypercars” and power grids. |
Conventional batteries supply electricity via chemical reactions between two electrodes, the anode and cathode, which typically interact through liquid or gel electrolytes. Solid-state batteries instead employ solid electrolytes such as ceramics. Solid-state batteries can provide more energy than conventional batteries for the same amount of weight or space.
“Solid-state batteries will be of huge benefit for electric vehicles, where the range is quite a key parameter,” says Noshin Omar, CEO and founder of Avesta Battery and Energy Engineering (ABEE) in Brussels. “Solid-state batteries are also much safer than conventional lithium-ion batteries, which use organic liquid electrolytes that are flammable and volatile.”
Now ABEE is helping develop a street-legal electric “hypercar,” the Fulminea, which is set to go to market in the second half of 2023. It will feature a hybrid battery pack that combines ABEE’s solid-state cells with ultra-capacitors.
“Currently our solid-state batteries have an energy density of about 400 watt-hours per kilogram, which is about double the typical energy density of commercial lithium-ion batteries on the market,” Omar says. “By 2025, we aim to achieve an energy density of 450 watt-hours per kilogram.”
