I can grab any Li-ion chemistry I want from Digikey and use it for experiments at home.
I’m actually a hobby electrical engineer and moderator of /c/ece here and like to discuss electrical engineering.
Batteries are more of a chemical engineering thing, but experiments are conducted with electrical inventions (opamps, microcontrollers, pcbs).
In any case, Digikey.com has plenty of batteries. But used batteries are risky, especially with how explosive Li-ion is.
IMO, Hobbyists shouldn’t be experimenting with Li-ion (or unprotected Li-ion) without substantial fire safety measures. It’s a well known explosive risk in our field.
But if you really want to experiment, buy a fire extinguisher and the old ‘Bucket of Sand’ trick. Keep watch over the batteries during your experiments, keep flammable objects away, leave the battery test inside the bucket of sand and keep the fire extinguisher closeby.
