Why are lithium ion phone and labtop batteries still legal considering their saftey risks? There are safer battery chemestries that aren't quite as energy-dense. But phones and laptops were capable-enough 15 years ago and performance-per watt is constantly improving. Sure, we might not be able to light up all the pixels on our screen and stream gigs of data constantly and won't be able to train AI models when our labtop is not plugged into the wall, but we sufficed just fine on the performance of last-decade's mobile devices.

The safety risks are marginal and you interact with plenty of other things/systems daily that are at least as dangerous.

All that said, I do think battery research is probably one of the most important things "we" can be doing (and energy storage in general), so I'm all about putting in the money and time to find improvements.
