The vanadium battery is electrochemically reacted through a different valence state vanadium electrolyte circulating through the electrode, thereby achieving mutual conversion between chemical energy and electrical energy. The vanadium battery consists of a stack, a vanadium electrolyte barrel, a circulation pump, a pipeline, and a battery management system. The stack consists of a series of cells connected in series. The monolithic battery is composed of an ion exchange membrane, an electrode, a conductive plate, a flow frame plate, and a sealing ring. The electrode is composed of a graphite felt and is placed in the flow frame plate between the ion exchange membrane and the conductive plate.
Our company uses its world-leading perfluorinated ion membrane, high activity electrode and new low flow resistance, low self-discharge, high energy efficiency stack to produce vanadium battery stack with low flow resistance, low resistance and high current density (>110mA/cm2). , higher than the peer 30mA/cm2), high power density (>130mW/cm2, higher than the peer 40mW/cm2), high energy efficiency (>83%@130 mW/cm2, 5-10% higher than the peer), module High degree of production, low production cost (about 2600 yuan / kW), long life cycle of charge and discharge (> 20,000 times)
