113F is not very hot at all.
what happens when the thing is sitting in a parking lot in florida, its black asphalt, its 3pm and the surface temp is 140 degrees on a sunny day with little wind and everything is sweltering.   its going to need to use power, in park, just to keep cool to operate.  now lets add a load to it, the radiant heat alone is going to kill it.

this is not going to be ready for mainstream.   and even that w/hr kg is not all that super.  some of the upper end lith cells can hit this benchmark.  what is solid state, they added a cap to it?     again, people love throwing the word solid state around yet there is no real hard line definition for it.    when you can show me an iso definition of what makes solid state then we'll be getting somewhere but until then, its a buzzword that people love to throw around that means, well, whatever they want it to.

And then there is the "semi-solid state" lithium battery.
