All-vanadium redox flow battery energy storage technology has leapt to a new level

On October 30, the world's largest and largest 100-megawatt-class flow battery energy storage peak shaving power station with the largest power and capacity provided by the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, was officially connected to the grid for power generation
.

The grid-connected flow battery energy storage peak shaving power station adopts the all-vanadium flow battery energy storage technology
independently developed by Dalian Chemical Institute.
This technology uses vanadium ions in different valence states as active substances, based on the oxidation or reduction reaction of vanadium ions in the positive and negative electrolytes, to realize the mutual conversion of electrical energy and chemical energy, and then realize large-scale storage and release
of electrical energy.
This technology has the characteristics of high safety, good reliability, large scale of output power and energy storage capacity, long life, high cost performance, recyclable electrolyte, and environmental friendliness, and has good application prospects
in the field of large-scale energy storage.

In recent years, Dalian Chemical Institute has continuously solved the key scientific and technical problems in the industrialization of all-vanadium redox flow batteries, broken through the key core technologies of all-vanadium redox flow battery energy storage, achieved a series of internationally leading technical achievements, carried out industrialization and promotion at home and abroad, and realized the export
of China's flow battery energy storage technology to developed countries.
