alt Hacker NewsLithium iron phosphate batteries are very practical. Chinese BYD has developed blade batteries using this type of battery and has become the global sales leader in new energy vehicles. However, this battery faces range limitations and the issue of how to improve charging speed. Solid-state batteries should be the next big thing, but mass production may not be feasible yet. At least, it might take 3 more years for commercialization, and that's still an optimistic prediction.

Solid state batteries and fusion power, always 3 years away.

Unless you want to charge in negative temperatures

Yes they are less dense but plentiful for typical passenger car (and not so much for full sized trucks or even "mid-sized" US SUVs).

I think CATL demonstrated 1MW charging on these already. Definitely shipping 500kW charging (tho best measure is still average km/hr).

Sodium will (great cold weather performance and even better charge rates), but it's less (vol) dense and prices won't reach LFPs for another 10-15 years (unless you believe hype, not actual analysts).
