Title:
CONDUCTIVE MATERIAL DISPERSION FOR SECONDARY BATTERIES, SLURRY FOR SECONDARY BATTERY ELECTRODES, ELECTRODE FOR SECONDARY BATTERIES, AND SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/074293
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a conductive material dispersion for secondary batteries which improves the dispersibility of a slurry for secondary battery electrodes and makes it possible to reduce internal resistance in a secondary battery over the long term. The present invention is a conductive material dispersion for secondary batteries that comprises a plate-shaped conductive material and a fibrous conductive material, wherein the ratio of the length of the fibrous conductive material to the maximum length of the plate-shaped conductive material in the planar direction is 0.1-100, and the aspect ratio of the plate-shaped conductive material in the planar direction is 1-5.
