I'm curious - if you take a normal Li-ion battery out of a phone (for example) and whack it with a hammer it'll put on a pretty decent and dangerous show. Can the same thing happen to a big battery?
I'd imagine they wouldn't be as 'flimsy' as the ones in a phone, and weight isn't really an issue so they could happily have some kind of extra insulation/shielding.
- askvictor 10y agoI think (could be wrong) that these 'big batteries' are just banks of small batteries- a bit bigger than AA cells - the same that run cordless power tools and (older) laptops (and Tesla cars)
- Florin_Andrei 10y agoYou mean the 18650 cells. I'm not sure if Tesla still uses them (they certainly did in the beginning), or whether they've switched to some proprietary format by now. EDIT: They still use the 18650, but plan to switch to a bigger format for the Model 3: http://fortune.com/2016/07/27/tesla-bigger-battery-gigafactory/ http://fortune.com/2016/07/27/tesla-bigger-battery-gigafacto...
- greglindahl 10y agoWhy yes, there's engineering that goes into stopping a fire from spreading. Here's some info about a fire safety test done to a Tesla Powerpack: https://electrek.co/2016/12/19/tesla-fire-powerpack-test-safety/ https://electrek.co/2016/12/19/tesla-fire-powerpack-test-saf...
- synicalx 10y agoNice, thanks for the link, I was sort of hoping it would explode violently but probably good that it didn't.

- epistasis 10y agoYes, but fortunately it's a bit easier to deal with than natural gas.
