Interesting. Is there a public spreadsheet or similar summarizing the most important properties of these new battery types? It takes forever to just research one of them in enough depth to understand their basic properties, and I’d like to compare many.
- fwungy 2y agoDOE puts out comparison papers at times, but I haven't looked in a while.
- ForOldHack 2y ago"The energy density of sodium ion batteries is low.It is only 100-150Wh/kg, while the energy density of lithium energy is 120-180Wh/kg. This means that for batteries of the same size, sodium-ion batteries can store much less energy than lithium-ion batteries.Jan 2, 2024" https://www.dnkpower.com/will-sodium-batteries-replace-lithium-batteries/ https://www.dnkpower.com/will-sodium-batteries-replace-lithi...
- shrx 2y agoThat's 20% less, not "much less".
- myself248 2y agoFurthermore, we're decades into lithium optimization, and sodium is yet quite young. Being within 20% so early in the game is remarkable!
- creeble 2y agoDepends on where you get your numbers: “The density of sodium batteries is still relatively low, between 140 Wh/Kg and 160 Wh/kg, compared to lithium-ion battery’s 180 Wh/Kg–250 Wh/Kg.” https://www.flashbattery.tech/en/sodium-batteries/ https://www.flashbattery.tech/en/sodium-batteries/
- h0l0cube 2y agoDepends on whether you're talking about a single battery cell or a pack.
