摘要： A zinc/air depolarized cell wherein the anode comprises zinc particles, aqueous alkaline electrolyte, 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.

摘要： A primary cell having an anode comprising lithium or lithium alloy and a cathode comprising iron disulfide (FeS2) or a mixture of iron disulfide (FeS2) and iron sulfide (FeS) and conductive carbon particles. A cathode slurry is prepared comprising the FeS2 or FeS2 plus FeS powder, conductive carbon, binder, and a solvent. The binder is preferably a styrene-ethylene/butylene-styrene (SEBS) block copolymer. There is an advantage discovered in utilizing a hydronaphthalene solvent to form the cathode slurry. The preferred solvent is 1,2,3,4-tetrahydronaphthalene or decahydronaphthalene and mixtures thereof. The slurry mixture is coated onto a conductive substrate and the solvent evaporated leaving a dry cathode coating on the substrate. Higher drying temperature may be used resulting in a dry cathode coating which resists cracking. The anode and cathode can be spirally wound with separator therebetween and inserted into the cell casing with electrolyte then added.
