Recent progress in graphene‐based electrodes for flexible

Apart from being used as the flexible current collector, flexible graphene electrodes can also be directly as the anode for flexible LIBs. Wallace's group 73 first studied the electrochemical performance of vacuum‐filtered graphene paper and found its poor capacity (about 90 mAh g −1 at 50 mA g −1 ) was mainly due to the agglomeration of nanosheets that hindered the transportation of

Battery felts for redox flow batteries

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.
