Cathode-active materials (CAM) are pivotal in determining battery performance, cost, and lifespan. As the battery technology industry expands and environmental concerns rise, CAM manufacturers are under increasing pressure to enhance sustainability while maintaining superior product quality. A significant challenge in the production process of CAM involves the purification of gas streams, such as O2 and N2, which are essential for various manufacturing stages. Clean Dry Air (CDA) is vital for transporting active materials within different process lines to meet stringent purity requirements. This case study explores how Pall Corporation's advanced filtration solutions addressed the pain points of a major chemical company constructing a new manufacturing plant for pure cathode-active materials.

Solution
A major company was setting up a new manufacturing plant and needed to install appropriate filtration solutions on its gas circuits. These circuits are integral to feeding multiple processing lines that produce pure cathode-active materials (CAM). The company faced several challenges:
High Purity Requirements: The CAM production process demands extremely high gas purity levels for transporting solids, which is crucial for optimal battery performance.
Pressure Constraints: Limited available pressure in the process necessitates the use of highly efficient particulate filters with low differential pressure (pressure drop).
Frequent Filter Changeouts: Existing filters cause a higher differential pressure, leading to more frequent filter replacements, increased downtime, and higher operational costs.
Inconsistent Quality: The current filtration solution failed to consistently meet the high gas purity standards required, affecting the overall quality of the CAM and ultimately, the performance of the batteries.
