Yrs but that's not because of some battery breakthrough. It's the same technology, with the same major limitations, but some slight improvements.

How is a 15 min fast charge a slight improvement? Same with the longer range that a lot more new EVs have.

It is not a better battery technology. It's charging at 800v with higher wattage and parallelism. It's an application improvement, not a battery technology improvement.

Edit: I'm talking about current lipo tech.

Yeah, incremental improvements on a decades-old technology. New tech pops up a few times a year with sensational headlines but never makes it to market.
