Even better, let's work out chemistries that don't have the same level of risk. We already have LFP, which is an order of magnitude less likely to combust. IMO we really shouldn't be using traditional lithium ion batteries for things like grid storage or home batteries where weight isn't a prime consideration. I wouldn't want one in my house, I'd use LFP instead. Or even better, LTO, though it's not as cost effective. If I have to sleep above it...
