Abstract

The present invention relates to one kind of slurry paper for no-mercury Zn-Mn cell with polymer electrolyte. The slurry paper includes base paper and slurry, and the slurry consists of one kind of polymer gel prepared with coordination ion liquid and organic mercury-replacing buffer liquid. The coordination ion liquid is prepared with urea, thiourea, zinc chloride and ammonium chloride; and the polymer gel is prepared with coordination ion liquid, PVA, PAM, PEG and crosslinking starch in certain proportion. The no-mercury Zn-Mn cell with polymer electrolyte can decrease the internal resistance of cell, improve dynamic discharge performance of cell, prolong the maintenance time and avoid environmental pollution caused by mercury.

Description

technical field

[0001] The invention belongs to the technology of using mercury-free pulp layer paper containing novel polymer solid electrolyte to replace the mercury-containing pulp layer paper in the current battery in the production of dry batteries. Background technique

[0002] The pulp layer paper plays the role of isolating the positive and negative electrode materials in the battery, allowing the electrolyte to pass through, absorbing a certain amount of electrolyte, and maintaining the normal discharge of the battery. The existing pulp layer paper is generally composed of base paper, adhesive, liquid retaining agent, paste and additives. Adhesives, liquid retaining agents and pastes are all water-absorbing polymer materials. Polyvinyl alcohol (PVA) is generally used as adhesive and barrier material. Carboxymethyl cellulose (CMC) sodium salt and polyacrylamide (PAM) are used as liquid retaining agent, and cross-linked starch and cross-linked etherified starch are ...
