Thickener for electrode paste and electrode paste composition for alkaline storage battery

摘要

The present invention relates to a thickener for electrode paste for an alkaline storage battery comprising a water-insoluble water-absorbent resin; a composition for an electrode paste comprising an active material, a conductive agent, a fluorine resin and a thickener, wherein the thickener comprises a water-insoluble water-absorbent resin; and an electrode paste for an alkaline storage battery produced by adding water to the composition for the electrode paste. The present invention provides electrode paste for an alkaline storage battery which allows thickening in a short time without forming undissolved powder lumps in the process of thickening by adding water, uniform application without sedimentation of active material or conductive agent even when used in a small amount, good applicability without sagging after application, and without liability of elution in electrolyte.
