Battery Separators

Improving the fabrication and performance of batteries
Our chemically resistant glass products, such as E, C, and ECR glass, are specifically engineered to meet the rigorous demands of lead-acid and lithium thionyl chloride battery systems. These materials are perfect for use as separators, slip sheets, pasting papers, and glass retainer mats, with their design and properties customizable to meet specific requirements.

Key Properties

Preventing Short Circuits:

Our separators act as a physical barrier between the anode and cathode, preventing direct contact that could lead to short circuits and potential battery failure.

Ionic Conductivity

Our advanced nonwovens allow the flow of ions between the anode and cathode while blocking the flow of electrons, which is essential for the battery’s operation.

Thermal Stability

Our E, C and ECR glass separators can withstand the internal heat generated during battery operation, helping to maintain battery integrity and safety under high temperatures.

Mechanical Strength

Our separators provide mechanical support to the electrodes, maintaining their position and structure during the cycling process, which is important for the battery’s mechanical integrity and durability.

Chemical Resistance

Our products resist the chemical environment within the battery, including the electrolyte, to prevent degradation and ensure long-term performance.

Enhancing Cycle Life

By maintaining separation and integrity over many charge and discharge cycles, separators contribute to the extended cycle life of the battery.

Applications

Our separator materials are used in:

Lithium ion batteries
Lead acid batteries
Vanadium flow batteries
