So Toyota thinks they're going to have a prototype of a competitive battery in 2025, with production volumes to follow later (I'd guess at least 2+ years). And they don't yet have a solution to the primary liability of solid state batteries, but maybe left unstated is that they DO have a path to solving the short lifespan problem.
So if they fill the inside straight, then they have technology coming in 2027 that will (might) be better than 2020 or 2017 technology. Sounds like a decade in arrears with at least, for this moment in time, a path to catching up all at once, sometime later.
Sounds like a losing strategy to me, with a non-zero chance of technological leadership or at least parity in 7 years. (And increasingly miserable technology between now and 2027; so all they have to do is hang on!)
THIS is the state of competition for the EV market? Maybe instead of Tesla with 20% market share, maybe 50% or something similarly outrageous is a better 2030 end game to be modeling...
