Function in the battery

What pasting paper does in plate manufacturing

Pasting paper is a thin, even, chemically stable glass fiber sheet applied to the plate surface during pasting. With the highest specific surface area in our range (BET ≥ 2.0 m²/g) and a tight 0.5–1.5 μm fiber blend, it holds lead paste uniformly through curing and assembly.

It is indispensable in modern lead-acid plate manufacturing — particularly for continuous grid pasting lines and applications requiring high reliability and durability.

01

Enhanced adhesion of active materials

Provides a porous, high-surface-area substrate for uniform application of lead paste (PbO₂ for positive plates, sponge lead for negative plates), ensuring strong adhesion between active material and grid and minimizing delamination during cycling.

02

Improved electrochemical efficiency

Capillary action facilitates efficient electrolyte penetration, enabling better ion exchange between the lead paste and sulfuric acid — optimizing reaction kinetics, prolonging battery life and reducing internal resistance.

03

Structural stability

Acting as a mechanical binder, pasting paper maintains electrode integrity during charge–discharge cycles and resists warping or cracking, especially in high-temperature or deep-discharge scenarios.

04

Optimized grid-to-paste interface

In continuous grid pasting technology, the paper ensures seamless contact between the lead grid and the pasted active material, minimizing interfacial resistance and improving current distribution uniformity.
