Embodiment 1

[0008] Embodiment 1: The laminated battery negative electrode conductive glue of the present invention is composed of ionic polymer material and slurry. In terms of weight percentage, one part of slurry is matched with one part of ionic polymer material, and the ionic polymer material is selected Acrylic acid-vinyl acetate copolymer, cross-linked starch is used as the slurry.

Embodiment 2

[0009] Embodiment 2: The laminated battery negative electrode conductive adhesive of the present invention is composed of ionic polymer material and slurry. In terms of weight percentage, one part of slurry is equipped with three parts of ionic polymer material, and the ionic polymer material is selected Crotonic acid-vinyl acetate copolymer, polyvinyl acetate, etherified starch and cross-linked etherified starch are used for the slurry.

[0010] The ionic polymer material and slurry described in the present invention can also be selected from one to three types of acrylic acid-acrylamide copolymers and crotonic acid-acrylamide copolymers. When two or three of them are selected, , the mutual dosage ratio can be determined arbitrarily. The slurry can also choose polyoxyethylene ether, polyacrylic acid, sodium polyacrylate, ammonium polyacrylamide, bismuth trichloride, indium trichloride, polyvinyl alcohol, polyethylene glycol, sodium hydroxymethyl cellulose and xanthan Glue, s...

Abstract

The present invention discloses a laminated cell negative electrode conducting gel. It is formed from ionic high-molecular material and pulp material according to the mixing ratio of 1-3:1. The ionic high-molecular material can be one to three kinds selected from acrylic acd-ethylene acetate copolymer, butenoic acid-ethylene acetate copolymer, polyvinyl acetate, acrylic acid-acrylamide copolymer and butenoic acid-acrylamide copolymer, and the pulp material can be one to three kinds selected from cross-linked starch, etherified starch, cross-linked and etterified starch, laurinol, polyoxyethylene ether, polyacrylic acid, sodium polyacrylate, polyacrylamide, indium trichloride, polyvenyl alcohol, polyglycol, sodium carboxymethyl cellulose and xanthan gum. Said invention can raise adhesion quality of zinc sheet and pulp layer paper.

Description

technical field [0001] The invention relates to a conductive glue, in particular to a negative electrode conductive glue of a laminated battery. Background technique [0002] Due to the lack of compatibility with grease, the existing conductive adhesive used for batteries cannot dissolve the grease on the zinc sheet well, causing the conductive adhesive to not be evenly distributed on the zinc sheet, which affects the adhesion between the zinc sheet and the pulp paper , resulting in poor battery stability. Contents of the invention [0003] The purpose of the present invention is to develop a kind of laminate battery negative electrode conductive glue. [0004] The invention aims to solve the technical problems of poor compatibility between the existing conductive adhesive and the zinc flake, resulting in low bonding quality between the zinc flake and the pulp layer paper and poor battery stability. [0005] The technical solution of...
