Lithium Manganese Iron Phosphate — LMFP 532 battery cells – are now claiming 4 million mile automotive use (6 million km). This suggests that the battery will be 9.5 times longer life than the average North American Automobile. Expect a 1,000 km range per 18 minute charge and at least 100 year lifetime with only small degradation of performance. Tesla has taken a patent on this after R&D sponsored in Dalhousie University in Nova Scotia. The 532 means the ratio 5 : 3: 2 of Nickle, Manganese, Carbon in the cathode. Use will be in EVs, Class 8 Trucks, Powerwall (home) and Megapack (grid) storage. Safety up to 60 C is greatly enhanced and tested. The charge time from 10% to 80% is measured at 18 minutes.
Tesla is opening new battery factories in Nevada, California and China exclusively for LMFP 532 cells and batteries. Some Tesla products already in slow transition to this new technology but massive deployment will depend on how fast the new factories can come into full production which is expected in 2024.
