New sodium-ion battery skips mechanical cooling with 97.9% efficiency
I’ve been hearing about these for a few years now. Huge if they work out at a large scale.

Interesting EngineeringNew sodium-ion battery skips mechanical cooling with 97.9% efficiencySyntropic Power and UNIGRID have entered a partnership to commercialize UNIGRID’s sodium chromium oxide battery chemistry in North America.Replying to @Return_of_Chippy@lemmy.world
Do you think this battery tech will be applied to portable power tools?
Replying to @UnfairUtan@lemmy.world
Nope. Too heavy for the power capacity.

While I get that this is the narrative, people are overstating this case. High end sodium batteries have a similar energy density range to lower end lithium batteries (~150-175 wh/kg). This idea that people wouldn’t buy a battery that is cheaper, safer, and has a much longer cycle life if it weighs a bit more or only runs 80% as long between the faster charges is puzzling at best.

They have less density than Li ion because of their honeycomb structure. They may have the same output per weight, but they have more volume.
