| 摘要 |
A zinc/air depolarized cell wherein the anode comprises zinc particles and aqueous alkaline electrolyte within said anode casing,- a cathode within said cathode casing,- and an electrolyte permeable separator between said cathode and anode,- and a glue comprising crosslinked polyvinylalcohol, preferably crosslinked with a boron containing compound, said glue located between the separator and a side of said cathode to adhesively bond the separator to the cathode. The cell may be in the form of a button cell. The glue provides a strong adhesive bond between the separator, desirably of microporous polypropylene, and the cathode. The glue promotes ionic conductivity at the separator/electrode interface even when the zinc/electrolyte ratio within the anode is elevated. |
