Cobalt is a transition metal (Co) widely used as a key material in lithium-ion battery cathodes, particularly in chemistries like NMC (Nickel Manganese Cobalt) and NCA (Nickel Cobalt Aluminum). It plays a critical role in stabilizing the cathode structure, enhancing energy density, and improving battery cycle life and thermal stability.
Role in Batteries:
Improves cathode stability during charge/discharge cycles
Increases energy density in high-performance cells
Enhances thermal safety by reducing risk of thermal runaway
Extends battery life by reducing structural degradation over time
