"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"

- 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/
