    摘要： A primary cell having an anode comprising lithium and a cathode comprising iron disulfide (FeS2) and carbon particles. The cell can be in the configuration of a coin cell or the anode and cathode can be spirally wound with separator therebetween and inserted into the cell casing with electrolyte then added. The electrolyte comprises a lithium salt dissolved in a nonaqueous solvent mixture which may include an organic cyclic carbonate such as ethylene carbonate and propylene carbon. The cell after assembly is subjected to a two step preconditioning (prediscahrge) protocol involving at least two distinct discharge steps having at lease one cycle of pulsed current drain in each step and at least one rest period (step rest) between said two steps, wherein said step rest period is carried out for a period of time at above ambient temperature. The preconditioning improves cell performance.

    摘要： A primary cell having an anode comprising lithium and a cathode comprising iron disulfide (FeS2) and carbon particles. The electrolyte comprises a lithium salt dissolved in a nonaqueous solvent mixture which contains an alkyl ester, preferably an alkyl acetate. The electrolyte solvent may also include an organic cyclic carbonate. A cathode slurry is prepared comprising iron disulfide powder, carbon, binder, and a liquid solvent. The mixture is coated onto a conductive substrate and solvent evaporated leaving a dry cathode coating on the substrate. The anode and cathode can be spirally wound with separator therebetween and inserted into the cell casing with electrolyte then added.

    摘要： An alkaline cell having an anode mixture comprising zinc particles, aqueous alkaline electrolyte, and molecular sieve additive. The cathode preferably comprises manganese dioxide. The cell may be cylindrical or any other shape or size. The molecular sieve additive preferably comprises a crystalline aluminosilicate material which is in at least a partially dehydrated state before admixture with the aqueous electrolyte, preferably potassium hydroxide. The aluminosilicate crystalline structure has average pore size between about 3 and 25 Angstrom. The addition of the molecular sieves to the zinc anode improves the cell's discharge capacity and service life. The molecular sieves preferably comprises between about 0.07 and 0.7 percent by weight of the anode mixture.
