GreatScott! tests ProLogium lithium ceramic batteries, a solid-state design. He measures their volumetric and gravimetric energy density, compares them to Li-ion and LiPo, and runs durability tests at the end.
HN commenters cite it as hands-on testing of a solid-state battery claim, though some remain skeptical until products ship.

There is a great video from GreatScott on youtube[0] about LCB (Lithium Ceramic Batteries) where he got hands on some of them and tests them for charging, usage and physical resilience (they work even if you cut off large parts of the battery). 0: this video
Everyone's been talking about breakthroughs for batteries for years. Until I see one on the shelf, it doesn't matter. Go make them better, and come back once they actually are! I've even seen ceramic batteries being tested on YouTube as long as 7 YEARS ago [0], but I still can't actually buy one. [0]: this video
The leakage of a battery isn't something you can stop. It's a big amount of stored energy released in a short while like a bomb. One Chinese company actually invented a flexible and solid battery that can even be cut without a risk of explosion but it doesn't scale to bigger capacities: this video
A similar product maybe? this video Solid state batteries from ProLogium. I contacted them earlier to for pricing.
