2000 recharge cycle vs 1000 recharge cycle is significant.

  Sodium is 4 times heavier than lithium which is even more significant. Having a car battery which weights 4 times more isn't viable. Also you can recycle the lithium from batteries quite easily.

    Weight is irrelevant when looking at on-site storage. Cost per KW storage and battery fade performance are more important factors. This is why they are saying this could be a game-changer for renewables. Being able to store energy cheaply is key. Something Lithium has been unable to deliver. Having a battery that is cheaper and lasts twice as long before needing replacing is significant.
