Lithium-free sodium batteries exit the lab and enter US production

newatlas.com Lithium-free sodium batteries exit the lab and enter US production

Two years ago, sodium-ion battery pioneer Natron Energy was busy preparing its specially formulated sodium batteries for mass production. The company slipped a little past its 2023 kickoff plans, but it didn't fall too far behind as far as mass battery production goes. It officially commenced…

50,000 cycles

Wow, a lifetime of 137 years at one cycle per day. This could make off-grid systems mainstream.
Lower power density, higher cycle life, safer. Sounds good for stationary power storage.
non-flammable end use

Safe and stable chemistry

Oh neat, finally a non-explody and/or unstable battery lmao
The mere fact that we can stop scorching the earth for lithium and cobalt is enough.
As usual there is absolutely no mention whatsoever anywhere in any of the articles I can find or from the company themselves about what the fucking price is
Sodium batteries are already in electric cars many months ago

Also you could buy individual cells on AliExpress

Sodium? Like, salt sodium?
Good video going over practical pros and cons currently:

I couldn't find much in the chemistry but this seems exciting.
That is some great news
Nuclear bros hate this one simple trick.
I didn't see anything about round trip efficiency. I've heard that's a big downside so it might make energy storage a hard sell.
Finally, some good fuckin' news. Curious to see if Fairphone will be the first to attempt adopting this.
Only thing I've seen that has worried me about them is how they seem to have turned a fire hazard into an explosive hazard in terms of battery safety.
