Description

Technical Field

[0002] The all-vanadium liquid flow battery uses vanadium ion solutions of different valence states as positive and negative electrolytes. The electrolyte is driven by an external pump to circulate between the storage tank and the battery stack. The electrolyte undergoes redox reactions in the battery stack to complete the charging and discharging process. The liquid flow frame is very common. Electrolyte is mostly introduced into the liquid flow frame to react chemically with the battery. Currently, the flow channels are mostly set in horizontal and vertical styles. There will be multiple large bends in the flow channel, which will cause the resistance of the electrolyte to increase when it circulates, increase the effective resistance of the battery self-discharge, and slow down the speed of self-discharge. In addition, when the battery is working, the electrolyte will undergo a chemical reaction in the liquid flow frame, and a large amount of heat will be generated during the chemical reaction.
