As many engineers will know, the battery industry has not yet achieved the perfect battery or rather cell technology. In almost every choice there is always a compromise to be made when selecting the chemistry which best suits a specific application. There are some fundamentals to keep in mind when considering a lithiumthionyl chloride (Li-SOCL2) cell or battery for a specific application.
Generally speaking a higher capacity cell is most commonly sought after. Herein lays a common mistake made when briefly studying a potential products specification sheet. This mistake occurs when the current delivery ability of the cell is overlooked.
There are some basic principles about lithium-thionyl chloride technology that should be considered. Two basic methods are employed by the manufactures, which produce this technology. Each method offers advantages and disadvantages. The two methods employed are referred to as the bobbin cell and the spiral wound cell.
