ion. the table in the Na-ion article seems to use “1000W/kg” without a source, and it shows lithium as being about a third of that even though the Li-ion article quotes figures up to 10kW/kg.

seems the editors of the two articles aren’t cross-checking eachother.

No, it seems like you have zero idea what you are talking about and are confusing W/kg with Wh/kg, which are very different metrics
