Standards Development
This document specifies the test methods of the chemical composition and physical properties of the electrolyte for vanadium flow battery.
This document is applicable to the electrolyte for vanadium flow battery.
Due to the stable performance, high safety and no self-discharge of the flow battery technology, the fire and explosion caused by thermal failure can be avoided during the charging and discharging process. The advantages of independent design and flexible configuration of the flow battery can be widely used in the development requirements of long-term energy storage projects. The global vanadium flow battery project has developed rapidly. By 2024, the cumulative installed capacity of the world has reached 2.8 GWh, and the corresponding output of the electrolyte has reached about 140,000 m3. The demand and production of vanadium electrolyte are increasing rapidly with the development of vanadium flow battery worldwide. Vanadium flow battery projects all over the world, including China, Germany, Denmark, Austria, Japan, USA, Canada, Spain, Italy, Australia, India, South Korea, South Africa and other countries.
Vanadium electrolyte is the key component material of vanadium flow battery, which has a decisive impact on the basic performance of vanadium flow battery. The chemical composition and physical properties of vanadium electrolyte directly determine the charging and discharging performance and cycle stability of vanadium flow battery. The standardization of vanadium electrolyte test method is the basis of the quality of vanadium electrolyte and the reliability of vanadium flow battery system, and it is also the basis of good cooperation between vanadium electrolyte production enterprises and application enterprises.
Therefore, the standardized and unified test method is the necessary basis for the specification and quality control of vanadium electrolyte products, which is of great significance for the development of vanadium electrolyte products and vanadium flow battery. As a result, it is necessary to develop a standard for the analysis of vanadium electrolyte
