Long life thionyl chloride cell

Patent ·
OSTI ID:5514290
;
An electrochemical cell is described having substantially longer storage life comprising a lithium anode, a thionyl chloride depolarizer and solvent, a lithium aluminum chloride electrolyte salt and a quantity of sulfur dioxide admixed in the solvent in an amount sufficient to regulate the growth of lithium chloride crystals formed on the lithium anode. This amount of sulfur dioxide is preferrably sufficient to cause the ratio of moles of lithium aluminum chloride to moles of sulfur dioxide to range from 0.9 to a most preferred range is from 1.0 to 1.
