Problems solved by technology

[0005] In the experiment, it was found that the above-mentioned plate-shaped structure conductor has extremely high requirements on the dimensional matching accuracy of the battery reaction chamber and the current collector, and it is easy to form warping deformation or crush the sandwich composite structure layer, resulting in uneven current inside the battery or even a local short circuit; in addition , the guide body placed in the reaction chamber in a zigzag manner reduces the actual height of the electrode suspension flow chamber, which is not conducive to the flow of the electrode suspension

Abstract

The invention discloses a cable-type diversion lithium-ion flow battery reactor, belonging to the technical field of a lithium-ion flow battery. Flexible diversion cables are arranged among sandwiched composite structure layers of the lithium-ion flow battery reactor and arranged in parallel, interior battery short circuit caused by rigid stress of a plate-like structure diversion body on the sandwiched composite structure layers is avoided during diversion on an electrode suspension liquid, and when the cables are electronic conductors, the cables also can be used for connecting a porous electrode collection layer and a battery lug for electron conduction and collection.
