Here are Jordan's numbers on raw materials cost for various types of batteries:- LFP – $8 kWh Liquid Metal Cell – $17 kWh Vanadium – $20 per kg- not sure how many kWh (10-20 wh/kg) High Nickel – $25 kWh LCO – $50 kWh – Lithium Cobalt Oxide. Of course the manufactured cost is different to the raw material cost. The Powerwall is Nickel-Manganese - my guess $18-$20 kWh Jordan states ( and I agree) LFP is currently to heavy and bulky for Powerwall. Eventually LFP will be a great option for home energy storage, but that may take some R&D and/or product redesign. Here is some interesting R&D:- UCLA team uses graphite to boost performance of lithium iron phosphate cathode materials Finding a way to improve the energy density of LFP batteries while retaining the great cycle life and low cost, would be game changing.
