Problems solved by technology

Compared with traditional lithium-ion batteries, lithium slurry batteries have the characteristics of regenerating by changing the liquid, but the distance between the electrode sheets of lithium slurry batteries is limited and the electrode sheets are thicker, so it is not conducive to the uniformity of battery liquid injection, liquid replacement, and electrolyte. Infiltration, and the wettability of the electrolyte directly affects the performance of the battery

Abstract

A lithium paste battery cell is provided, which includes a plurality of positive and negative plates overlapping with each other and an isolation layer, wherein the lithium paste battery cell furthercomprises a flexible support current guiding cable arranged along the surface of the positive electrode plate or the negative plate between the positive electrode plate and the negative plate, the supporting current guiding cable being located in one or more of the following positions: between the positive electrode plate and the isolation layer, between the negative electrode plate and the isolation layer, and between a plurality of isolation layers. The fluidity of an electrolyte inside the lithium paste battery can be improved by the supporting current guiding cable, and the wettability ofthe electrolyte to the positive plate and the negative plate can be improved. In addition, the supporting current guiding cable can also provide support for the positive plate and the negative plate,reduce the deformation of the positive plate and the negative plate and the pressure on the isolation layer, thereby avoiding the breakage of the isolation layer or the short circuit problem, and improving the safety of the lithium paste battery.

Description

technical field [0001] The invention relates to the field of lithium slurry batteries, in particular to a lithium slurry battery cell and a lithium slurry battery with supporting guide cables. Background technique [0002] Lithium slurry battery refers to a lithium battery or lithium ion battery that contains all or part of the slurry electrode form. The electrode in the slurry state can avoid the problem of cycle life attenuation caused by the electrode material falling off or loosening in traditional lithium ion batteries, and increase The relative proportion of active materials in the battery system can increase the overall energy density of the battery system and reduce battery production costs. Compared with traditional lithium-ion batteries, lithium slurry batteries have the characteristics of regenerated liquid replacement, but lithium slurry batteries have limited electrode sheet spacing and thicker electrode sheets, which is not conducive to battery liquid injection...
