What Is The Lifespan Of Li-SOCl2 Battery?

The lithium thionyl chloride battery exhibits a unique characteristic where a thin film of lithium chloride is generated on the negative electrode's lithium surface during idle periods. This film acts as a barrier, hindering the chemical reaction and ionization process between lithium and electrons. Consequently, this particular battery showcases minimal natural discharge in comparison to other battery types. The battery's output voltage remains steady at 3.6V, ensuring a consistent power level up to the present moment.

Lithium thionyl chloride batteries have a remarkable characteristic - a nominal voltage of 3.6V, making them the highest among all commercially available disposable batteries. These batteries can maintain a substantially constant voltage even during continuous discharge, until the power is completely depleted. However, it is worth noting that obtaining a large current from such batteries can be challenging. In fact, when current is initially passed through, there may be a short period of time where the voltage drops. This aspect needs to be carefully considered during the design of power supplies.
