color me skeptical about lithium batteries in general, but I do have at least a little bit of faith in people's ingenuity. When you get right down to it, that's capitalism. Someone takes a risk, that risk pays off (or not) and generally, people succeed.
It's only been 150 years or so since oil has been processed into various fuels and handling those fuels (gasoline, diesel, etc.) certainly was dangerous back in the day. We routinely handle that stuff without thinking much about it anymore. Lots of tractor-trailer rigs hauling it around and you rarely hear of any kind of incident.
While I think we're probably decades away from any kind of "battery power" that even comes close to what we get out of fossil fuels, I do think the problem is eventually solveable.
With taxpayer money, of course.
And that's the part I object to. If there are those who want to invest in renewable fuels, have at it. Incur your failures and learn from them. Let me know when you have something that works. But batteries ain't it -- at least for now.
