WONTAI POWER's Self-Developed "Electrode Chlorine Evolution Performance Testing Device" Granted National Invention Patent

Recently, WONTAI POWER's self-developed "electrode chlorine evolution performance testing device and testing method" was granted a national invention patent.

In VFB, the volume and concentration of vanadium species in the electrolyte directly determine the battery's capacity and energy density, while their electrochemical activity and stability are critical to battery performance. Although the mixed-acid system offers advantages in terms of the overall cost of the energy storage system, the release of chlorine gas (Cl₂) due to the introduction of hydrochloric acid poses significant safety risks.

Addressing this industry pain point, WONTAI POWER's newly patented invention provides a key solution. The device can accurately calculate the concentration of chlorine gas evolved in the reaction system, thereby enabling the selection of suitable electrode materials to effectively mitigate the adverse effects of the chlorine evolution reaction on battery performance and system safety.
