Wish they gave the current energy density of lithium batteries for comparison.
It’s a range, but LFP is generally in the 90-160wh/kg and NMC (lithium manganese cobalt oxide) tops out around 275 wh/kg.
It’s not quite double, but doubles the density of most mass manufactured cells. Time will tell if it gets to scale, but it’s a step in the right direction.
Feeling stupid: doesn’t this mean more energy per kilogram is possible with Na cells?
