So it is actually pretty good. Sodium ion is not future tech, it is current tech as of 2023 you can purchase then in small quantities. There is a MIT student testing one on Reddit batteries. The density was about 110. So the 160 Wh/kg is very good.
They didn’t say anything about it, but the volume is about double. So even if they are good enough for cars it is not easy to retrofit.
Don’t forget that one of the issues with batteries is supply chain ( we need more materials than what is being produced). Probably all these batteries will co exist to avoid material shortages. Sodium ion may become the standard for the auxiliary 12/48V systems and for low range EV ( probably not in the huge USA ) and for PEV. One key is the anode that uses hard carbon where lithium ion uses a more refined form classified as graphite and graphite shortage could be an issue short term.
They are probably not cheaper than lithium ion right now due to limited scale but are predicted to be half the cost of current lithium ion. Lithium ion will also fall. There is tech like LFMP coming to further reduce lithium ion cost.
LFP is about 190 Wh/kg, NMC is about 260 Wh/kg.
