Top Use Cases

• Electrodes in Flow Batteries: Battery felts are widely used as electrodes in redox flow batteries, which are large-scale batteries used to store electricity from renewable energy sources such as solar and wind. The felt material has a high surface area and good electrical conductivity, which facilitates chemical reactions within the battery. This improves battery performance, efficiency, and lifespan. Flow batteries with carbon felt electrodes are particularly suitable for grid-scale energy storage systems.
• Electrodes in Lithium-Ion Batteries: Battery felts can also be used as electrode materials or electrode backing in lithium-ion batteries. Their porous structure allows better movement of ions and electrons during charging and discharging. As a result, batteries can charge more quickly and store more energy. This property makes battery felts useful in applications like electric vehicles and portable electronics.
• Fuel Cells and Hydrogen Technologies: Battery felts are used in fuel cells and hydrogen production systems as gas-diffusion layers or electrode supports. The porous structure allows gases and liquids to flow easily while maintaining electrical conductivity. This helps fuel cells operate efficiently and improves their durability. These technologies are important for clean energy and hydrogen-based power systems.
• Thermal Insulation in High-Temperature Systems: Battery felts, especially graphite felts, can withstand very high temperatures. Because of this property, they are used as thermal insulation in high-temperature furnaces and industrial processes. They help protect equipment from heat loss and maintain stable operating conditions in industries like semiconductor manufacturing and photovoltaic production.
• Catalyst Support and Filtration in Chemical Processes: Battery felts can also serve as support materials for catalysts and filtration systems in the chemical industry. Their robust structure and chemical resistance enable them to retain catalysts and facilitate chemical reactions more efficiently. They can also filter chemicals and liquids in industrial processes, improving purity and system performance.
