No mention of energy density compared to existing batteries?

Is it sodium battery tech starting to have an effect?

ams6110 Jul 2, 2017 View on HN

Looks like it's up to about 10x better than li-ion.

whoomp12342 Feb 25, 2022 View on HN

there is lots of alternative battery tech in research right now for the very reason you propose

dharma1 Aug 11, 2019 View on HN

I think it's 20-30% better energy density than current batteries

christkv May 27, 2024 View on HN

Cool whats the energy density of this? The sodium batteries also look promising.

Are you sitting on next-generation battery tech the rest of us don't know about?

Can Sodium-ion batteries really replace Lithium-ion batteries?

known Dec 20, 2016 View on HN

Not without Lithium-ion https://en.wikipedia.org/wiki/Energy_density#Energy_densitie...
