Electrolyte for Zn-Br flow battery

- Molecular Formula: ZnBra (solution)

- Usage : Energy storage material for Zn-Br flow battery /Electric energy is stored or released via the reduction and oxidation of Zn and Br ions.

● Zn-Br flow battery?

- The needs for large scale energy storage system (ESS) is increasing as the shortage of electricity and the penetration of renewable energy increase. Zn-Br flow battery, which is highly economical, stable and scalable is a candidate that will lead future ESS market.

● Characteristics

- High purity: synthesized with high purity zinc and bromine compounds, Hanchang’s ZnBr2 solution shows low level of impurities which are the source of hydrogen evolution.

- In-house synthesized quaternary ammonium salt (QAS) reacts with bromine to form stable complex.

- High purity ZnCl2 supporting electrolyte is added to improve the stability

- Hanchang has wider analysis equipment to quickly meet customers requests.

  Production capacity : 30 MT/month.
