    I’m very interested in experimenting with na-ion this summer. Their specific power/energy densities are still low compared to li-ion but their cells are already available for cheaper than li-ion despite having not reached economies of scale yet. They also seem to be reporting (unverified in data sheets) longer cycle lifespans and larger operational temperature ranges. Could make for a very nice self managing solar powered pi project soon.

    If costs drop fast, the lower density won’t even matter- it could be the kick in the ass for utility scale battery storage to take off.

      iirc the tldr with salt batteries is:

      pros: cleaner (no lithium) wear down slower than liion resistant to temps

      cons: lower capacity when they fail, they fail hard (e.g suddenly stop working)

      theyre IMO very ideal for offsite energy storage (where space is not a problem) or a residential battery wall. as they dont have the risk of catching on fire.

      IMO if any nation is trying to solarize their energy grid, backing salt ion is the better long term option.

      Utility scale storage has already taken off.

      But yea this could be a huge jump in the market.
