Lithium slurry battery cell and lithium slurry battery with supporting guide cable

Abstract

The invention provides a lithium slurry battery cell, which includes a plurality of positive and negative electrode sheets stacked crosswise and an isolation layer, wherein the lithium slurry battery cell also includes a flexible supporting current-conducting cable, and the supporting conductive The current cable is arranged between the positive electrode sheet and the negative electrode sheet along the surface of the positive electrode sheet or the negative electrode sheet, and the supporting current guiding cable is located in one or more of the following positions: between the positive electrode sheet and the isolation layer, between the negative electrode sheet and the isolation layer Between and between multiple isolation layers. By supporting the guide cable, the fluidity of the electrolyte in the lithium slurry battery can be improved, and the wettability of the electrolyte to the positive electrode sheet and the negative electrode sheet can be improved. In addition, the supporting guide cable can also provide support for the positive and negative electrodes, reduce the deformation of the positive and negative electrodes and the pressure on the isolation layer, thereby avoiding the damage or short circuit of the isolation layer, and improving the efficiency of the lithium slurry. battery safety.

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...

AI Technical Summary

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
