Pulp paper for flexible batteries and the preparation method thereof

Abstract

The invention relates to a pulp paper for flexible film zinc-manganese battery, which comprises a base paper with only one layer and slurry coated on both sides which comprises modified starch, polyelectrolyte, water retaining agent, organic/inorganic composite corrosion inhibitor, and electrolytes wherein the polyelectrolyte is one or more of polyglutamic acid, sodium polyglutamate, potassium polyglutamate, polyaspartic acid, sodium polyaspartate and sodium polyaspartate, and the water retaining agent is a sodium salt or a potassium salt of hyaluronic acid. The pulp paper in the invention has the advantages of thin layer, simple composition, fast absorption speed, large liquid absorption capacity, good liquid-retaining ability, good ionic conductivity and low wet resistance which boosts good application value in the field of flexible battery technology. The flexible film zinc-manganese battery applying the pulp paper has advantages of low resistance, large battery capacity, good high current and excellent pulse discharge capacity.
