| The application of graphite felt on Vanadium redox flow battery |
| graphite felt, Vanadium redox flow battery |
Graphite felt is perfect for Vanadium redox flow battery, it has good electrode performance and high quality.
Vanadium redox flow battery (Redox Flow Battery VRB, Vanadium) is a kind of active substance, which is a kind of redox battery. As early as in the 1960s, iron - chromium system redox battery came out, but vanadium oxidation reduction cell is in 1985 by the University of New South Wales in Australia Marria Kacos proposed after more than 20 years of research and development, vanadium battery technology is reaching maturity. In Japan for peaking power plants and wind power energy storage to the fixed type (as opposed to electric vehicle) vanadium battery is developing rapidly, the high power of vanadium redox battery energy system has been put into practical, and efforts to promote the commercialization process.
Vanadium battery electric energy to chemical energy stored in different valence vanadium ions in sulfuric acid electrolyte, the pump is connected with the the electrolytic liquid into the battery pile body, under the action of dynamic mechanical, the circulation in the closed loop of the different liquid storage tank and the half cell, the proton exchange membrane as a separator for battery, electrolyte solution parallel flow across the electrode surface and the electrochemical reaction, through the double electrode plate collection and conduction current, which makes stored in the solution of chemical energy into electrical energy. This reversible reaction process enables the vanadium battery to successfully complete the charging, discharging and recharging. Cathode electrolyte composed of V and V (IV) ion solution composition, cathode electrolyte by V (III) and V (II) ion solution composition, battery charge, positive material for V (V) ion solution. The negative electrode V (II) ion solution, after the battery discharge, positive and negative, respectively V (IV) and V (III) ions in a solution, the internal battery by H + conductive.
