T/HBAS 007-2022 Highly pure vanadium pentoxide

Scope

Scope: This document specifies the technical requirements, test methods, inspection rules, and packaging, marking, storage, transportation, and quality certificates for powdered high-purity vanadium pentoxide produced by the calcination method. This document is applicable to high-purity vanadium pentoxide used in vanadium battery electrolytes, chemical industries, and special vanadium alloy materials. Main technical content: Vanadium pentoxide is widely used in metallurgy, chemical industries, and other fields, mainly for the smelting of vanadium iron. With technological advancements, the application scope of vanadium is continuously expanding, and some industries have higher purity requirements for vanadium products. Compared with traditional solid-state batteries, vanadium batteries have a longer lifespan, can withstand high current charging and discharging, and are easy to adjust battery capacity by replacing the electrolyte solution, enabling "timely charging" of the battery. They have great application prospects in energy storage systems for renewable energy such as solar and wind power. As a raw material for vanadium batteries, high-purity vanadium pentoxide has broad application fields and huge market potential. Therefore, the development of the "High-Purity Vanadium Pentoxide" standard, which specifies 22 chemical components including vanadium pentoxide content and exceeds the national standard, is of great significance for improving the quality of high-purity vanadium pentoxide products in Hubei Province, enhancing the core competitiveness of related enterprises, and gaining a leading position in standard-setting.
