The present invention relates to a 1.5 volt primary electrochemical battery cell having an alkali metal lithium negative electrode (eg lithium), a positive electrode (eg containing iron disulfide) and a nonaqueous electrolyte. The electrolyte has a solute comprising lithium iodide dissolved in an ether containing solvent comprising 1,2-dimethoxypropane solvent component and up to 30% by volume of 1,2-dimethoxyethane. When 1,2-dimethoxypropane is used in place of at least most of 1,2-dimethoxyethane in a solvent, the cell provides excellent discharge capacity even at low temperatures while maintaining excellent discharge capacity at room temperature.n n n n Electrochemical Battery Cell, Low Temperature |
