ER battery, lithium thionyl chloride
Nominal voltage: 3,6V non-rechargeable
Nominal capacity: 450 to 19000 mAh
Package shape: cylindrical AAA to D
Lithium thionyl chloride batteries have a metallic lithium carbon (the lightest of all the metals) and a liquid cathode comprising a porous anode current collector filled with thionyl chloride.
They deliver a voltage of 3.6V and are cylindrical in shape with spiral electrodes for power applications and a bobbin construction for prolonged discharge.
The lithium thionyl chloride batteries has the; highest voltage and energy, the longest storage, and the lowest self-discharge rate. These kinds of batteries are ideal for long-term applications.
These batteries are used in meters (electricity, gas, water, heat), alarms and security devices, emergency location beacons, tracking, RFID and professional electronics applications.
