Abstract

A metal-alkaline battery having a reduced corrosion rate and enhanced electrochemical properties comprises an anode that includes derivatives of polyethylene glycol (PEG). The PEG derivatives have one or more hydrophilic moieties attached to the ends of the PEG chain. The hydrophilic moieties may be a carboxyl group or a carboxymethyl group. A preferred PEG derivative is plyethylene glycol, bi-carboxy methyl ether (PEG BCME).
