If you need a refresher on why the solid-state battery is so important—potentially a game-changer in the EV space—you can read this primer. But there are kinks to iron out. The solid electrolyte material surrounding the battery cells has, in Toyota's testing regime, developed gaps that affect battery performance and service life when utilized in battery electric vehicles (BEVs). That's why, at least initially, Toyota will implement the tech in hybrids (HEVs), where the issue is less of a concern, while simultaneously developing it further for BEVs down the road.
