China is going to bring into production from this year a lot of sodium ion batteries. For me the weight and density of the batteries is not as important as recharge cycles and cost as that would price out more carbon producing electricity generation

- jansan 3y agoThere are sodium ion batteries available at aliexpress. The claimed advantges (written in an unintentially comical way) are: - better safety - same number of cycles as LiFePo - much better capacity at low temperatures - protects environment (?) I would take that with a truckload of salt. Also, price is roughly 50% higher than LiFePo. On many product images there is an outdoor winter scenery. So performance at very low temperatures seems to be the main selling point.
- rootusrootus 3y agoLFPs do more cycles and are still cheaper. Sodium ion isn't going to make much of a dent in that market until the price can get below LFP.
- xbmcuser 3y agoYeah but prices wont have the same kind of fluctuations as lithium does because of demand and supply. And as manufacturing picks up economies of scale should start bringing the price down
