1 month agoWhat’s interesting to me is the power to weight ratio. Sodium-Ion is at ~1000 W/Kg vs Li-Ion at ~175-425 W/Kg. EVs could maybe have less weight and cost in the future because of this.
According to a paper published in 2020 here, the specific energy and energy density are in line with what you are saying. But according to the article that Wikipedia cited here, sodium batteries show the opposite.
You’re probably right but it looks like there’s conflicting info about this currently.
