NCM811 Cathode Material M2-S Single Crystal Alumina Coating Single Crystal Nickel-Cobalt-Manganese 811
Our NCM811 Cathode Material M2-S is a high-performance lithium-ion battery cathode material engineered with advanced single-crystal technology and precise single-crystal alumina (Al₂O₃) coating. As a single-crystal NiCoMn 811 material (Ni:Co:Mn = 8:1:1), it combines ultra-high nickel content with a unique surface modification process—effectively solving the issues of cycle stability and thermal safety that plague traditional polycrystalline NCM811. This product delivers exceptional energy density, long cycle life, and excellent rate capability, making it the core material for next-generation high-energy lithium-ion batteries used in electric vehicles (EVs), energy storage systems (ESS), and high-end consumer electronics.
