Graphite & Carbon Felt for Energy Storage
Stationary electrochemical energy storage is central to balancing supply and demand as power generation shifts toward renewable sources. Technologies such as redox flow batteries (RFBs), sodium-sulfur cells, and lithium-ion systems each place distinct demands on their internal components — from electrochemical stability and electrical conductivity to long-term resistance against corrosive electrolytes.
Carbon-based materials are well suited to these environments. Graphite and carbon felt provide the chemical inertness, electrical conductivity, and thermal stability that electrochemical cells require across thousands of charge and discharge cycles. In flow batteries specifically, felt electrodes and graphite bipolar plates are fundamental to stack performance and service life.
Max Graphite supplies standard and custom graphite, carbon felt, and carbon-carbon composite components for energy storage system manufacturers and integrators. Whether the requirement is a felt electrode cut to stack dimensions or a machined graphite end plate produced to drawing, we deliver materials specified for long-duration electrochemical service.
Applications
- Felt electrodes for vanadium and other redox flow battery chemistries — permeable carbon and graphite felts serving as the active electrode substrate within the cell stack
- Bipolar plates for flow battery stacks — dense, electrically conductive graphite plates that separate individual cells while conducting current between them
- End plates and current collectors — machined isostatic graphite components that distribute current and provide mechanical compression at the ends of a battery stack
- Graphite foil gaskets and sealing elements — flexible graphite sheet cut to shape for electrolyte sealing between cells in electrochemical stacks
- Thermal insulation for high-temperature battery systems — rigid carbon felt panels used in sodium-sulfur and ZEBRA battery enclosures operating above 300 °C (572 °F)
- Heating elements and fixtures for electrode heat treatment — graphite and C-C composite components used in furnaces during the thermal activation or graphitization of battery felts
- Thermal management layers for lithium-ion battery packs — graphite foil used as a heat-spreading interlayer in module-level thermal management
- Rigid felt insulation for battery material processing furnaces — carbon felt boards providing thermal containment in kilns and furnaces used to produce anode and cathode precursors
