Right now the Sodium-ion tech is still in its infancy. It's higher priced than it will be as the market scales. I expect it will find more use in stationary storage capacity than mobile devices as it's power density is a bit lower, but the material cost is much lower and therefore potentially useful for utility grade or home power banks. It's theoretically able to benefit from a lot of the same technology that Lithium cell batteries use, so cross-chemistry innovation potential is high.

Just came acoss this. A density of 175Whr/kg in mass produced EVs.

[-] GreenBeard@lemmy.ca 2 points 2 hours ago

Yes. Could be exciting in the near future. As the article points out, it's a bit less power dense than lithium, and has a slightly worse power to weight ratio, but that doesn't necessarily make it bad, it's just better suited for different market niches than lithium. I could see urban cab companies and other short range fleet uses preferring sodium-ion, as they'll have a higher rate of cycling and wear, and the cheaper cost of a battery will represent a significant net benefit. I think consumer grade vehicles are going to prefer Lithium for the foreseeable future though.

Yeah. Probably buses too. What's really exciting for me is the significant potential for lowering total vehicle cost.

Boycott US

Overview:

The community dedicated to boycotting the US until they stop fascism, restore full democracy and start following international law.

Americans have a moral obligation to resist Donald Trump and project 2025 at every turn.

America is a flawed democracy currently being ruled by oligarchs. Stop the backslide! Dont let America become the next Hungary.

America needs to challenge the court rulings of citizens united v. fec and shelby county v. holder, protect the media, implement independent district drawing, and the single transferable vote so they don't end up having people stay home in life-changing elections because they cannot vote for their favourite candidate.
