US Patent 11211607 Bipolar electrode comprising a loaded carbon felt

Bipolar electrodes comprising a carbon felt loaded with a polymer material and a nanocarbon material are described herein. The bipolar electrodes are useful in electrochemical cells. In particular, the loaded carbon felt can be used in bipolar electrodes of zinc-halide electrolyte batteries. Processes for manufacturing the loaded carbon felt are also described, involving contacting (e.g., dipping) a carbon felt in a mixture of solvent, polymer material and nanocarbon material.
