Not all chemistries are created equal
Not true.
There are several reactions possible and a popular non exploding one for storage battery use is the lithium iron phosphate (LiFePO4) battery, also called LFP battery (with "LFP" standing for "lithium ferrophosphate"(Def. from wikipedia). This will be my choice when I go off grid. I believe Tesla’s PowerWall is the exploding type. If so, would you want one strapped to your living room wall?
