Solid-state batteries, which have long carried hopes for turbocharging electric vehicle sales, will not be the “game-changer” the market expected, according to the head of one of the world’s largest car battery manufacturers.
Hiroaki Koda, who heads a joint battery venture between Toyota and Panasonic, told the Financial Times in an interview that new liquid-based lithium-ion batteries would be dominant for the next 10 years.
Prime Planet currently makes square lithium-ion batteries, half of which are used in Toyota’s hybrid and plug-in hybrid vehicles, while Panasonic supplies smaller cylindrical batteries to power Tesla’s electric vehicles.
