Abstract

The invention discloses a lithium ion flow battery reactor. The current collecting plate of the present invention adopts a corrugated plate, which can make the electrode suspension flow into each chamber evenly, increase the current collecting area at the same time, and effectively improve the rate characteristics of the battery; set a steering cover on the side of two adjacent battery modules , so that the electrode suspension flows through each battery module in turn, forming an S-shaped flow field, speeding up the flow rate of the electrode suspension, increasing the effective volume of the battery reaction, which can greatly increase the energy density of the battery, and at the same time make each battery module The electrode suspension in the medium flows evenly; the liquid inlet diversion chamber and the liquid outlet diversion chamber with the main channel and the split channel can reduce the influence of the turbulence caused by the liquid inlet and outlet on the uniformity of the battery; the inert gas The airflow channel through the gas protection chamber and the cooling plate enters the battery reactor, which ensures the airtightness and heat dissipation of the entire battery reactor, and at the same time isolates the water vapor and oxygen in the air from contacting the electrode suspension.

Description

technical field [0001] The invention belongs to chemical energy storage battery technology, in particular to a lithium ion flow battery reactor. Background technique [0002] With the increasing shortage of global energy, the development of emerging energy industries is imperative, but must rely on energy storage technology. Energy storage power station is a breakthrough in the field of energy storage technology. Electrochemical energy storage plays an important role in the application of electric energy due to its advantages of high energy density, simplicity and reliability.
