Our company is a high-tech enterprise dedicated to R&D and industrialized production of new energy storage vanadium battery technology. The company has an independent R&D center, an ion-exchange membrane workshop, a vanadium battery stack assembly workshop, a vanadium electrolyte preparation workshop, and a modular vanadium battery system assembly and testing workshop. The company has internationally leading patented technologies and important achievements in vanadium battery high-performance perfluorinated ion membranes, high-active electrodes, high-efficiency stacks, wide-temperature vanadium electrolytes, and full-system modularization of vanadium batteries, and has huge advantage.

With independent research and development, the company has realized the recycling of perfluorinated ion membrane (PIEM) in low cost, high crystallinity, large tensile modulus, isotropy and long life, which has broken the monopoly of this market by foreign countries. Company production of vanadium battery with high power density, high energy efficiency, wide operating temperature, electrolyte modular degree is high, the whole life cost is far lower than the lead-acid, traditional battery such as lithium electricity, etc, which is the best choice for photovoltaic power generation, wind power, smart grid, the peak valley electricity, communication base station, standby power supply, electric cars and quick charge.

Vanadium has a unique characteristic of having four different stages of oxidation. In each of the four stages, Vanadium contains a different electrical charge and is therefore used as a catalyst to store energy. In order to convert this electrical energy into a chemical compound, it requires two electrodes, called a “stack”. This stack consists of many cells; each one contains two half-cells that are separated by a membrane. In the half-cells the electrochemical reactions take place as soon as electrolytes flow past the membranes. Hence, the reduction or oxidation leads to the charging or discharging of the battery. The stack is connected to two different tanks and one electrolyte tank contains the positive V4+ and V5+ redox couples, the other the negative V2+ and V3+ redox couples. These energy-carrying liquids circulate through the stack by pumps.
