Sodium Ion Breakthrough to Alter Lithium vs Sodium Battle?

Lithium has twice the energy density of sodium. Sodium ion are cheaper to make Lithium has a longer life cycle Sodium ion is safer Sodium ion has better low temp performance During testing, the hydrated version held nearly twice as much charge as standard sodium-ion cathode materials. Game changer?

7 automakers betting big on sodium-ion batteries for budget EVs

Analysts suggest that sodium-ion packs are 20-40 % cheaper than lithium-ion phosphate batteries once large-scale production is achieved.
