BYD's LFP blade batteries - heavy but extremely safe.

Ultra safe, cheap, big LFP pack. Gotta love how it 'fails'


I wouldn't drive a 5000lbs EV with a pack like this, but i think it's cool that they were able to make the pack so safe that it wouldn't even emit much smoke.

Would be cool if the same thinking applied to other chemistries to at least help limit the chemical reaction's speed.

Where do they get these numbers ..
500 Wh/kg ???

I also scratched my head on that one. It may be relative to one component of the battery, and the presenter got something mixed up? idk.

Basically these batteries come out to around 160whrs/kg with packaging, which is actually impressive by lifepo4 standards, but not by >2011's NMC standards

Maybe they should have said Wh/ Ltr ?

Actually, you can already order a sample on Aliexpress. Thanks to the length of 960 mm, it will be a questionable for use elsewhere than in cars or stationary applications.
