That is A battery. The thermal management, safety mechanisms and infrastructure are fundamentally different when you are doing a dozen or two EV's worth or batteries simultaneously. I am not convinced that is practical in a consumer setting, or - to go back to the original topic - as a solution for people who don't have private parking to charge at.

As is noted elsewhere in the thread, it isn't simply a battery problem.

Intriguing. That would be a game changer. Of course, the next question is how soon before it can compete at the current battery's price point? If it ships in 2025 as the article suggests, it sounds like 2030 is likely the earliest it might widely replace today's batteries.
