BYD has started construction on its sodium-ion battery facility in Xuzhou, Jiangsu province, with a total investment of RMB 10 billion and a planned annual capacity of 30 GWh.
While a range of sodium-ion cathodes are being developed, the batteries packing the most energy use layered oxide cathodes. These batteries are good enough to deliver cheaper passenger EVs capable of 150-250 miles. Recent analysis has shown that the latest sodium-ion battery packs can even undercut the cost of LFP batteries thanks to their cheaper raw materials.
more or less the main draw. Theyre bigger (so there will be slightly less room in a car) but due to their cheaper nature, they’re a good target for evs with lower range (which will naturally be default in budget cars). They also work better in colder environments and the wear cycle is potentially longer. the con is when its worn, its REALLY worn
