Li-ion battery is the very big and expensive key component for current BEV. But there's no chance Japan to win cheap Li-ion race for China/EU/US because it needs much energies and materials. Energies need to be clean for the future exporting. Japan is now in bad situation for clean cheap energies, and no materials. So they also bet other techs, but I wish Toyota bets more for Li-ion BEV now.
