According to Toyota's website their development partner is Panasonic. The Prime Planet Energy & Solutions subsidiary has 5,000 employees and was started in 2020.

Most of Electrovaya's projections for solid state commercialization hint at 2025. We will see who get's there first. 

I have to admit, given the comparative size of Electrovaya's R&D effort and Toyota's effort we would all be insanely fortunate if Electrovaya prevails in the solid state race. 

I think our more certain gains will come from adoption of the Infinity platform by bus, truck and energy storage markets.
