Lithium batteries last as long as one battery out of thousands decides to thermal runaway, and then you have to replace all of them (as well as the facility they were all housed in).

It’s pretty hard to make one of these solid state blades catch fire: https://youtu.be/CGQwqWqzkNA

Does that happen with LFP? It is supposed to be safer.

		In short no. LFP is very safe. People have done tests involving shotguns, flamethrowers, hammers/nails, etc. And while that destroys the battery, they don't tend to explode, combust, burn uncontrollably, etc. These are nice party tricks with predictable outcome if you understand the chemistry (it's inherently safe).
