Lithium Manganese Oxide (LMO) Spinel Cathode LiMn2O4
CAS Number: 1317-34-6
Lithium manganese oxide (LMO) spinel cathode material offers low cost, high thermal safety, and excellent rate capability due to its 3D lithium-ion diffusion pathways, making it suitable for hybrid EV, power tools, and blended NMC+LMO cathode formulations. Low cobalt and nickel content reduces material cost and supply chain exposure.
