Abstract

The invention discloses a pump-free lithium ion flow battery and belongs to the field of a chemical energy-storing battery. The pump-free lithium ion flow battery comprises a plurality of battery subsystems, an anode liquid preparation tank, a cathode liquid preparation tank, an anode liquid collection tank, a cathode liquid collection tank, an anode conveying tank and a cathode conveying tank. An electrode suspension solution is pushed by gravity and inert gas pressure to circularly flow, so as to avoid using a pump. The pump-free lithium ion flow battery has the advantages of simplicity in operation and convenience for controlling, reduces mechanical loss of a battery system and improves the whole efficiency and the safe use performance of the battery.

Description

technical field [0001] The invention relates to a pumpless lithium ion flow battery, which belongs to the field of chemical energy storage batteries. Background technique [0002] The widespread use of electrical energy is considered one of the greatest achievements of mankind in the twentieth century. The power industry has become one of the most important basic industries in the country. The modern power system is developing in the direction of large power grids and large units, and the development of new energy grids has also entered a new stage.
