Very interesting company. They started with a way to produce graphene at scale, then went looking for something to do with it. Their first idea was to use it as a cement additive. They have since used it as friction reducer in engine oil, and are selling it in Australia, Canada, and soon the US, as a radiator coating to improve HVAC performance.
You must be in your early 20s. People who have used nickel-cadmium will never forget how shitty they were.
People who have never used dry cell batteries haven’t a clue.
My RadioShack Golden Arrow was a beast with those 7.2v NiCads.

NiMH batteries weren’t that awesome either.
I still like them. All their devices had replaceable batteries.
I don’t think NiCd batteries where too bad.
