The Introduction of Vanadium Flow Battery
Vanadium batteries can conduct electrochemiccal reactions through the electrolyte circulationg through the electrode,which can realize the conversion between chemical energy and electrical energy . Vanadium battery is composed of stack , vanadium electrolyte bucket, circulating pump,pineline and battery management system . The stack is composed of a single battery series. The single battery is composed of ion exchange membrane , electrode , conductive plate, liquid flow frame plate between the ion exchange membrane and the conductive plate. The lower part and upper part of the liquid flow frame plate are respectively provided with vanadium electrolyte solution and outlet flow channel.

Physical method, no pollution, short process flow; Recover all components of electrolyte, seperator and electrode materials with high recovery rate; It can handle both lithium iron phosphate batteries and ternary lithium batteries; The profit is good.

1. The definition of Cascade utilization: It is the process of screening the decommissioned batteries from the electric vehicles and sorting them into groups then applying them for other places. 2. Price of the cascade utilization: About 30% to 50% of the new batteries' original cost which has a price advantage. 3. Related laws and regulations The Chinese government advocates the cascade utilization of power batteries, and the companies using the cascade utilization should be responsible for the safet risks. 4. Application markets (1) Energy storage field; (2) Electric bicycles; (3) Other fields that replace lead-acid batteries.

China new energy products account for more than 50% of the world total amount. Central South University is a renowned university in China, and over 60% of China's new energy companies have close relationships with Central South University. Professor Li Jian of Central South University is a well-known expert in the field of new energy in China. The "Zhengyuan Institute for Energy Storage Materials and Devices " with Professor Li Jian as the key person which has 8 professors, more than 50 post-doctoral, doctoral, and master researchers, and published more than 300 science and technology papers; over 120 patents have been declared and more than 70 authorized.
