    I don’t expect it so quickly, but hopefully lithium ion batteries (and variants like Li-poly, LiFePO4, etc)

      Sodium batteries are already commercially available and although their volumetric energy density and round trip efficiency is lower than lithium I think they are a promising alternative to lead acid and some lithium applications.

      Can you explain why and how? Do you imagine other (better?) batteries, or the disappearance of the need for batteries?
