Description

technical field

[0001] The invention relates to the field of batteries, in particular to a novel anode electrolyte for an all-vanadium redox flow battery and its application. Background technique

[0002] With the depletion of fossil energy all over the world and the continuous enhancement of people's awareness of environmental protection, renewable energy power generation technology is more and more popular. Renewable energy mainly includes wind energy, solar energy, biomass energy, ocean energy, etc., which are usually converted into electrical energy for use. These renewable energy power generation is obviously discontinuous and unstable due to the influence of geographical and meteorological conditions. In order to smooth and stabilize the power generation output of renewable energy, solve the time difference between power generation and power consumption, and improve power quality and grid reliability, it is necessary to develop high-efficiency energy storage technolog...
