Not just that, but Toyota also made the bet that solid-state batteries will be better than aqueous electrolyte li-ion ones, and that they will be available soon. With that assumption, it would be foolish to invest a lot into li-ion battery manufacturing. Turned out, solid state batteries are much harder to mass-produce than they thought. Supposedly they will have prototype this year.
