NOVELTY - A zinc/air depolarized cell (210) comprises an anode casing (260) and a cathode casing (240); an anode mixture (250) comprising zinc particles and aqueous alkaline electrolyte within anode casing; a cathode within cathode casing; an electrolyte permeable separator between cathode and anode; and a glue comprising a crosslinked polyvinylalcohol. The glue is located between the separator and a side of the cathode to adhesively bond the separator to the cathode. The glue comprises polyvinylalcohol crosslinked with a crosslinking agent comprising a boron containing compound.    USE - As batteries for electronic hearing aids including programmable type hearing aids.    ADVANTAGE - The improved separator glue results in a durable adhesive bond of changed bonding morphology (compared to prior art) which resists deterioration in ionic conductivity, especially during the cell's midlife. The modified glue shows improved wettability and better water retention. These benefits lower midlife voltage dip. The polyvinylalcohol crosslinked with boron containing compound can be produced in a viscous liquid, which can be readily coated uniformly onto a surface of the separator, preferably of microporous polypropylene. When the separator is coated in this manner and applied directly to the catalytic cathode, a durable adhesive bond is produced at the separator/cathode interface. The glue coating dries to form a crosslinked film bond between the separator and cathode preventing deterioration in ionic conductivity at the separator/cathode interface, especially during the cell's midlife period. Such adhesive bond does not appear to be adversely affected by the presence of alkaline electrolyte in the anode or increased mechanical bending forces on the cathode caused by anode expansion. The separator/cathode adhesive bond resulting from the improved glue resists drying of the separator/cathode interface. The separator coated with the improved glue promotes ionic conductivity at the separator/cathode interface, even when the anode mixture is prepared with high zinc/electrolyte weight ratios between 3.3 and 6.0, more preferably between 4.0 and 5.5. The improved separator glue also reduces the magnitude of transient voltage dips, which may typically occur in zinc/air cells having anodes with high zinc/electrolyte weight ratios.    DETAILED DESCRIPTION - A zinc/air depolarized cell (210) comprises an anode casing (260) and a cathode casing (240); an anode mixture (250) comprising zinc particles and aqueous alkaline electrolyte within anode casing; a cathode within cathode casing; an electrolyte permeable separator between cathode and anode; and a glue comprising a crosslinked polyvinylalcohol. The glue is located between the separator and a side of the cathode to adhesively bond the separator to the cathode. The glue comprises polyvinylalcohol crosslinked with a crosslinking agent comprising boron containing compound, polyamide-epichlorohydrin or ammonium zirconium carbonate. The glue is made by applying an aqueous solution comprising polyvinylalcohol, water, and a boron containing compound as a coating between the separator and the cathode. The coating is subsequently dried to crosslink at least a portion of the boron containing compound comprising boron with diol groups within the polyvinylalcohol structure, thereby adhesively bonding the separator to the cathode.
