Sodium-ion battery technology has an inherent advantage over other power-storage technologies because it uses low-cost materials that are sustainable and widely available. Prototype cells deliver energy density in excess of 140 Wh/kg, with a design performance of 155 Wh/kg in 10Ah pouch cells. Earlier post.). Earlier post.).
