Title:
SLURRY FOR FLEXIBLE ELECTRODES, AND FLEXIBLE ELECTRODE USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/031460
Kind Code:
A1
Abstract:
According to the present invention, it becomes possible to produce a flexible electrode having both of electrical conductivity and flexibility by preparing a slurry using a specific emulsion and specific carbon black and then applying the slurry. In one aspect of the present invention, a flexible electrode having both of electrical conductivity and flexibility can be produced by using a slurry prepared using an emulsion and carbon black, wherein the emulsion comprises at least one polymer component selected from the group consisting of an acrylic polymer, a urethane polymer, a fluorine polymer, a urea polymer, a chloroprene polymer and a butadiene polymer and has a pH value of 6.5 to 8.0, and the carbon black has a DBP absorption amount under uncompressed conditions of 150 to 300 mL/100 g and a BET specific surface area of 35 to 140 m2/g.
