> Sounds competitive with Lion and possibly cheaper? What’s the catch?
All previous works on sodium batteries showed very low cycle lives for both cathodes, and anodes.
Since they are not giving it out now, I guess that's it. And this may well be why they keep nailing solely on the point of it being operational at -20C° (which is a big thing for any lithium battery, still)
- baybal2 5y agoAnother thing I will note is them specifically comparing this to an LFP battery. CATL been very late to the LFP party, especially for the high-end automotive LFP cells. Companies which made a bet on LFP early are now coming with 200+wh/kg cells, which is already bigger than commodity automotive NCA, something which Foxconn (CATL) makes most money on. This is a kick below the waistline move to at least throw doubts about business expansion for LFP makers. Currently, 200wh/kg LFP cells are just only now hitting the market, and these LFP cell manufacturers are still making the lion share of their revenue, and profit on storage class, and low-end cells. If LFP manufacturers believe the new chemistry can wipe out their current cash cow, they will think twice about putting money to expansion in automotive cells.
