Cathode Active Materials

Explore advanced filtration solutions for cathode active materials that improve contamination control, enhancing efficiency and quality.

  

 

 

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 CAM significantly impacts the battery's performance, energy density, cycle life, and safety.

 

Challenges faced by CAM manufacturers

 

Manufacturers of 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.

Watch our video to explore the transformative CAM process and understand how essential filtration enhances battery performance.
