Manufacturing methods for high-energy, low-cost lithium manganese iron phosphate (LMFP) cathode active materials
Background LiFePO4 (LFP) cathode materials deliver excellent safety and cycle life but offer limited energy density, due to a low operating voltage (3.4V). Introducing manganese to form LiMnxFe1-xPO4 (LMFP) can boost specific energy 10% to 15% by raising the voltage up to about 3.8V, but the sluggish kinetics of Mn²⁺/³⁺ redox require small...
