GMG’s Graphene Aluminium-Ion Battery Update: Minimal Temperature Rise Identified While Fast Charging (graphenemg.com)

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.

NiMH batteries weren't that awesome either.

I still like them. All their devices had replaceable batteries.

My RadioShack Golden Arrow was a beast with those 7.2v NiCads.

People who have never used dry cell batteries haven’t a clue.

I don't think NiCd batteries where too bad.
