Product Description
We are one of the fastest growing companies, engaged in manufacturing and exporting of Battery Electrolyte. It is prepared by dissolving vanadium pentoxide (V2O5) in sulfuric acid to make it strongly acidic in nature. This electrolyte makes the battery capable of carrying large amount of chemical potential energy. Offered Vanadium Redox Battery Electrolyte allows V to exist in the solution in 4 oxidation states, to make a battery having just one electro-active element instead of two.

What role of electrolyte in flow batteries?

Electrolyte not only plays conductivity role, but also the carrier of active substance, which is a core part of the VFB battery system. When charging, the positive turns into V4.5+ from V3.5+ and negative turns into V2.5+ from V3.5+, while discharging, it is the opposite to achieve energy store. So, improving the electrolyte density is the effective way to improve battery stored energy.

Where to use?

Vanadium battery electrolyte only used in vanadium battery for businesses, universities and research institutions vanadium battery and key materials testing, and can meet needs of peaking power storage, wind and solar power energy storage projects.
