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.

Battery news is always like this has never in my lifetime lead to revolutionary changes. We had tons of incremental changes though!

Lithium-polymer batteries didn't take off until the 2000s. Those (and the lithium-ion they were built on) were pretty revolutionary, at least as much as this aluminum-ion is supposed to be. That ought to count. (Unless you're less than 20 years old, in which case "never in my lifetime" is probably accurate, and you should count yourself lucky that you never had to deal with arrays of D batteries, or the mediocre but technically rechargeable nickel-cadmium batteries.)

Ha! Same thought at pretty much the same time. Good to see you fellow elder.

Yeah, I remember having to put extra batteries in some devices, because the 1.5v AA alkalines vs. 1.2v AA NiCads add up when you need 10 of them.
