A new type of stack vanadium battery energy storage system relates to an energy storage system. Through the improvement of the stack structure, a new type of non-leakage stack vanadium battery energy storage system is provided. 

It includes a liquid storage system, a liquid guide system, and a stack. The liquid storage system is connected to the stack through the liquid guide system, which is characterized in that the stack is composed of battery cells, and the battery cells include a guard plate, a partition, and the guard plate and the partition plate form a unit space, The horizontal cross section of the space enclosed by the guard plate and the partition plate is a fan ring; 

The space enclosed by the guard board and the partition board is provided with electrode felt, bipolar plate, ion exchange membrane, and the ion exchange membrane is located in the center of the above space. The two sides of the ion exchange membrane are symmetrically arranged with electrode felt and bipolar plate, electrode felt, bipolar plate, and ion exchange membrane are arranged along the cylinder axis. The electrode felt on both sides of the ion exchange membrane is used for the flow of positive and negative electrolyte respectively.
