What is Cathode Active Materials?
Cathode Active Materials (CAMs) are crucial components in the cathode of a battery, particularly in lithium-ion batteries. These materials undergo electrochemical reactions that enable the storage and release of electrical energy. The choice of cathode active materials significantly impacts the battery's performance, energy density, cycle life, and safety.
Challenges faced by Cathode Active Material (CAM) manufacturers
Manufacturers of Cathode Active Material (CAM) encounter numerous challenges due to the inclusion of various other chemicals in CAM, and the need to meet specific particle size distribution, preserve crystal structure, control surface area and porosity, and adhere to rigorous contaminant level specifications.
