Abstract

The invention discloses a lithium-ion flow battery reactor. A collecting plate is a corrugated plate, electrode suspension liquid can flow into cavities evenly, the collecting area is increased, and the multiplying power performance of a battery can be improved effectively; steering coves are arranged on sides of two adjacent battery modules, so that the electrode suspension liquid flows every battery module sequentially, an S-shaped flowing field is formed, the flowing speed of the electrode suspension liquid is accelerated, the effective volume of the battery reaction is increased, the energy density of the battery can be improved greatly, and at the same time, the electrode suspension liquid in battery modules flows evenly; a liquid inlet diversion chamber and a liquid outlet diversion chamber with a main flowing channel and a branch flowing channel can reduce effects on battery uniformity, which are due to a turbulent flow phenomenon caused by liquid inlet and liquid outlet; inert gases enter a battery reactor through gas flow channels of a gas protective chamber and a cooling plate, the gas tightness and the radiating performance of the whole battery reactor are guaranteed, and at the same time, water vapor and oxygen in the air are prevented from being in contact with the electrode suspension liquid.

Description

technical field [0001] The invention belongs to the chemical energy storage battery technology, in particular to a lithium ion liquid flow battery reactor. Background technique [0002] With the increasing shortage of global energy, the development of the emerging energy industry is imperative, but it must rely on energy storage technology. Energy storage power station is a breakthrough in the field of energy storage technology. Electrochemical energy storage plays a pivotal role in electric energy applications due to its high energy density, simplicity and reliability. [0003] Lithium-ion flow battery combines the advantages of lithium-ion battery and flow battery, and is a new type of rechargeable battery with high energy density and low cost. The lithium-ion flow battery consists of a positive electrode suspension pool, a negative electrode suspension pool, a battery reactor, a liquid pump (or other power system) and a sealed pipeline. Among them, the positive electrod...
