But I think they’re inherently safer? I wouldn’t be surprised if we see some sort of wide ban of lithium batteries on planes at some point. Maybe sodium ones would be allowed and they’d have that specific utility. “AirSafe Power Certified”
It's not a complete ban. See https://www.tsa.gov/travel/security-screening/whatcanibring/... and https://www.faa.gov/hazmat/packsafe/portable-electronic-devi... and especially this bit:
> When portable electronic devices powered by lithium batteries are in checked baggage, they must be completely powered off and protected to prevent unintentional activation or damage.
Spare batteries and power banks are strictly required to be carry-on and not in checked baggage, but you can put a laptop in checked baggage as long as it's powered off.
Even after a recent fire, South Korea just tightened the rules (eg no charging on flights) But they’re still allowed.

I think we might just have “AirSafe” certified batteries allowed only at some point. Or TSA approved ones. The ban would make a hell of a lot more sense than liquids
I remember when laptops used to have pluggable batteries. You could even take one extra with you, or buy one extended battery with more capacity.
