Bipolar plates are one of the key components vanadium redox flow batteries. They electrically conduct and physically separate adjacent cells in series provide structural support to stack. exposed harsh conditions due acidic electrolyte high potential differences which occur Therefore, material needs fulfil good electrical conductivity, sufficient impermeability mechanical stability as well long...

We report the performance of a quinone-bromide redox flow battery and its dependence on electrolyte composition, flow rate, operating temperature, electrode and membrane materials and pre-treatment. The results of this study are used to develop a cell with a peak galvanic power density reaching 1.0 W/cm 2 .

A framework for improving cell design and providing researchers with low-cost, open-source, 3D-printed redox flow battery test cells.

This report describes the design of diaminocyclopropenium-phenothiazine hybrid catholytes for non-aqueous redox flow batteries. The molecules are synthesized in a rapid and modular fashion by appending diaminocyclopropenium (DAC) substituent to nitrogen phenothiazine. Combining versatile C-N coupling protocol (which provides access diverse derivatives) with computation structure-property analys...

3D graphene-nanowall-decorated carbon felts (CF) are synthesized via an in situ microwave plasma enhanced chemical vapor deposition method and used as positive electrode for vanadium redox flow battery (VRFB). The carbon fibers in CF are successfully wrapped by vertically grown graphene nanowalls, which not only increase the electrode specific area, but also expose a high density of sharp graph...
