Cathode-active materials (CAM) are the core of lithium-ion batteries—driving performance, cost-efficiency, and longevity. As demand for high-performance batteries grows, manufacturers are pushing the boundaries of purity in their production environments.
This case study highlights how Pall Corporation partnered with a leading industrial gas provider to implement 3 nanometer (nm) filtration for oxygen service in a new CAM facility, setting a new benchmark for gas purity in battery manufacturing.

Results
The customer was constructing a state-of-the-art facility to supply ultra-pure gases to CAM production lines. Their goal: achieve 3nm particle retention in oxygen service an ambitious target critical to battery quality and safety.
Why 3nm Filtration Matters:
- Trace contamination could degrade cathode materials, reducing battery life.
- Particulates risked disrupting cell assembly, increasing defect rates.
- Frequent maintenance and rework would drive up operational costs.
- In high-energy density applications, compromised gas purity could threaten safety and reliability.
Having seen Pall's success in similar high-spec projects, the customer turned to us for a solution they could trust.
Pall's technical team worked closely with the customer's engineering and operations teams to design a filtration system capable of meeting the stringent 3nm particle retention requirement for oxygen service.
The solution centered around Pall's Emflon® PF filters, which are rated at 0.003 micron and specifically engineered for high-purity gas applications. These filters are constructed with proprietary PTFE membranes that offer exceptional particle retention while maintaining high flow rates and low pressure drops, critical for continuous, high-volume CAM manufacturing.
- Extended Filter Life: Low differential pressure across the Emflon® PF filters reduced wear and tear, significantly extending service intervals.
- Minimized Downtime: Fewer changeouts and simplified maintenance improved uptime.
- Scalability: Modular design allowed for easy expansion as the customer scaled up CAM production capacity, ensuring long-term adaptability.
This solution not only met the technical challenge but also demonstrated Pall's commitment to innovation and customer-focused engineering.
The Outcome
This project reinforced Pall's reputation as a go-to partner for mission-critical gas applications in CAM production.
- Successfully achieved 3nm particle retention in oxygen service.
- Improved operational efficiency through reduced maintenance and downtime.
- Delivered a scalable solution ready to support future growth.
Bottom line:
Pall's deep expertise, flexible design approach, and commitment to collaboration ensured that performance and reliability were never compromised even under the most demanding conditions.
