OverviewDesignHistoryAttributesOperationSpecific energy and energy densityApplicationsDevelopment
The electrodes in a VRB cell are carbon based. Several types of carbon electrodes used in VRB cell have been reported such as carbon felt, carbon paper, carbon cloth, and graphite felt. Carbon-based materials have the advantages of low cost, low resistivity and good stability. Among them, carbon felt and graphite felt are preferred because of their enhanced three-dimensional network structures and higher specific
