PRIMARY BATTERIES - Li-SOCl2 3.6V Battery

Lithium thionyl chloride (Li-SOCl2) batteries, or ER batteries, are a main member of the lithium primary battery family. ER batteries use lithium metal as anode (negative) and a mixture of carbon and thionyl chloride (SOCl2) as cathode (positive). It is well known as its highest voltage (nominal 3.6V) and highest energy density.
