We supply battery felts in standard sizes up to 1350 mm (53") in width in 25 m (82 ft) rolls. Beyond that, we produce carbon and graphite felts in customer- specific dimensions. The entire in-house value chain ensures the quality of SIGRACELL ® battery felts from SGL Carbon and thus contributes to optimizing battery performance.
Increasing the power density and energy efficiency of the flow batteries is key to breaking through the cost bottlenecks, which is closely related to porous fiber felt electrodes (PFFEs), in which redox reactions take place.
Permeable electrodes made of SIGRACELL carbon and graphite felts are the first choice for high-temperature batteries like redox flow batteries. Our felts are used for anodes as well as cathodes.
The sizes we provide are even enough to cover the needs of large-scale redox flow systems. We supply battery felts in standard sizes up to 1350 mm (53") in width in 25 m (82 ft) rolls. Beyond that, we produce carbon and graphite felts in customer- specific dimensions.
Our standardized photovoltaic power generation and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
