The production of lithium batteries requires precision, efficiency, and strict safety measures, especially when handling battery slurry—a mixture of active materials, binders, and solvents used in electrode manufacturing. To ensure smooth material transfer, many manufacturers rely on aluminum diaphragm pumps, designed to handle the unique challenges of battery slurry processing.
These diaphragm pumps provide a contamination-free, efficient, and reliable method for moving cathode material slurry within electrode production lines. Their explosion-proof design makes them suitable for hazardous maenufacturing environments, ensuring compliance with strict industry safety standards.
This article explores the features, benefits, and applications of these pumps and how they enhance lithium battery production.
Battery slurry transfer is a crucial step in lithium battery manufacturing, as it directly affects electrode quality and, ultimately, battery performance. Traditional pumping methods often struggle with the viscous and abrasive nature of battery slurries, leading to issues such as:
• Material buildup that clogs pipelines and slows down production
• Inconsistent flow rates, affecting slurry uniformity and electrode coating quality
• Chemical incompatibility, causing premature pump wear and increased maintenance needs
• Safety risks, particularly in environments where flammable solvents are present
The explosion-proof pneumatic diaphragm pump overcomes these challenges with a sealed, air-powered system that ensures consistent and contamination-free slurry transfer.
These pumps are engineered to handle the rigorous demands of lithium battery production. Here’s what makes them an ideal choice:
1. Chemical-Resistant PTFE Diaphragm for Maximum Durability

1. What is a diaphragm pump, and why is it used for battery slurry transfer?
A diaphragm pump is a fluid transfer pump that uses a flexible diaphragm to create pressure, moving liquids without direct contact between the fluid and pump components. It is ideal for battery slurry transfer because it ensures safe, controlled, and contamination-free movement of abrasive materials.
2. How does a pneumatic diaphragm pump work?
A pneumatic diaphragm pump operates using compressed air to flex a diaphragm back and forth, creating suction and discharge cycles. This air-powered mechanism makes it ideal for hazardous environments where electrical pumps may pose safety risks.
3. Why is PTFE used for the pump diaphragm in battery applications?
PTFE (Teflon) diaphragms provide superior chemical resistance, ensuring longevity when handling highly reactive battery slurries. They prevent material buildup and wear, reducing the need for frequent replacements.
4. Are these pumps suitable for automated production lines?
Yes, these air-operated diaphragm pumps are fully compatible with automated battery manufacturing systems. Their flange connections allow for seamless integration into existing production setups.
5. How do explosion-proof diaphragm pumps improve workplace safety?
By eliminating electrical components, these pumps reduce the risk of sparks and ignition in flammable environments. Their sealed design also prevents chemical exposure, ensuring a safer working environment for operators.
