NCM9055 (LiNi0.90Co0.05Mn0.05O2) cathode is an ultra-high nickel layered oxide material for lithium-ion batteries. The elements in NCM90 play different roles in battery operation: (a) 90% Nickel (Ni): The active material responsible for high capacity. (b) 5% Cobalt (Co): Included primarily for structural stability. (c) 5% Manganese (Mn): Included for safety and structural integrity. It has the following advantages:
(1) Highest Energy Density: With 90% nickel, NCM9055 pushes the theoretical capacity limit of layered oxide cathodes. This significantly increases the specific energy (Wh/kg) of the battery cell, which is crucial for maximizing EV range. NCM90 can deliver an initial discharge capacity of around 225-230 mAh/g.
(2) Lowest Cobalt Content: The cobalt fraction is slashed to just 5% (from 10% in NCM811 and 20% in NCM622). This dramatically: (a) Reduces Raw Material Cost: Cobalt is the most expensive and supply-constrained metal. (b) Improves Ethical Sourcing: Reduces reliance on cobalt mining, which is associated with ethical and environmental concerns.
The polycrystalline NCM9055 powders are surface coated with alumina for improving conductivity and cycling stability.
