Mass sodium-ion battery released
 

We don't need no expensive lithium*

*HiNa Battery has produced what it is calling the world's first mass production run of sodium-ion batteries which don't use expensive lithium.

The first batteries havea GWh capacity but this will increase from 3-5 GWh next year. The only downside is that*sodium is quite a bit heavier than lithium and so its energy capacity is not so high. However it is catching up.*

At the moment it can manage 160 Wh/kg energy density, and has also hinted that its next generation Na-ion cells will surpass the 200 Wh/kg threshold. Tesla's much touted affordable 4680 battery that now goes in the Model Y returned just 244 Wh/kg energy density in recent tests, the sodium-ion cells are not to be underestimated, considering the affordability of their raw materials.
