NCM811 (LiNi0.8Co0.1Mn0.1O2) is a high-energy, nickel-rich cathode material for lithium-ion batteries. It is part of the Nickel-Cobalt-Manganese (NCM) family and is considered a more advanced, high-performance chemistry. It has the following advantages:
(1) High Energy Density: Nickel is the primary driver of capacity. With 80% nickel, NCM811 can store significantly more energy than its predecessors (like NCM111 or NCM622). This translates directly to longer range for electric vehicles (EVs) or longer battery life for electronics.
(2) Lower Cost: It uses 50% less cobalt than NCM622 (10% vs. 20%) and even less compared to older chemistries. Given cobalt's high price and volatile supply chain, this reduction makes batteries much more economical to produce.
The polycrystalline NCM811 powders are surface coated with boron for improving conductivity and cycling stability. By contrast, the pristine NCM811 can be used for comparison or further surface modification.
