Fiber flock for lead acid battery plates

Negative Expander

Fibers are incorporated into paste mixes to bind together the particles and reduce shrinkage during the curing process. They also assist in reducing the loss of pallets with handling from the curing process onwards in production. The fibres do not affect adversely the battery performance unless they are present in larger amounts than 0.5 wt.%. At this level and beyond, the fibres appear to prevent a change in the active material dimensions during discharge and charge.
