Lithium Thionyl Chloride Battery

Nominal voltage: 3.6V
Temperature range: -55℃+80℃
Product specifications: ER34615 / ER26500 / ER18505 / ER14505


The rated voltage of lithium thionyl chloride battery is 3.6V, and the working voltage varies with the load, generally between 3.0V and 3.6V. Its working voltage is the highest among all single batteries at present.

The battery has a mass specific energy of up to 500WH/Kg and a volume specific energy of up to 1000WH/L, which is the highest specific energy in the current battery. It can be divided into three types according to its use: capacity type, power type and high temperature type.

Lithium Thionyl Chloride Battery

Lithium thionyl chloride battery is especially suitable for long time discharge, the load voltage is very stable, more than 90% of the capacity can be released in the voltage is almost constant high platform;

Lithium thionyl chloride batteries can be used in extreme harsh environment, conventional batteries can be used in -55℃~+85℃ environment, special batteries can be used in up to 150℃ environment;

The annual self-discharge rate of the battery is less than 1% at room temperature.

It can be stored for up to 15 years at temperatures below 35℃.

Application scenarios of lithium thionyl chloride batteries

Lithium sulfuryl chloride battery can be used in various fields, mainly used in smart card meters (water, electricity, gas meters), computer support power supply, medical equipment, wireless communication, oil drilling, portable communication equipment, scientific research instruments, remote control data acquisition system, special applications and other electric equipment.

The bobbin LiSOCl2 battery has the following performance characteristics:

1.Higher energy density and higher capacity: The tube LiSOCl2 battery provides the highest energy density of any main battery: up to 710 Wh/Kg and 1420 Wh/I. These cells also have the highest capacity in weight and volume of any commercial battery technology.

2. Extended temperature range: The LiSOCl2 3.6V battery can operate in the temperature range from -55°C to +125°C. However, to maximize capacity, standard cylindrical wafer batteries are rated for a maximum temperature of +85°C. Specially modified batteries can be extended for both maximum and low temperatures.

3, high working voltage: shuttle type LiSOCl2 battery open circuit voltage is 3.67V, working voltage can reach 3.6V.

4, Longer life: Bobbin LiSOCl2 battery has excellent shelf life and long-term reliability, due to the very low annual self-discharge rate. Depending on the manufacturer, bobbin LiSOCl2 batteries stored at room temperature can lose between 7% and 30% of their initial capacity over a 10-year period.

5. Patented Safety features: The bobbin LiSOCl2 battery provides unparalleled safety due to its unique “fail-safe” construction. These batteries contain no heavy metals and are the most environmentally friendly of all.
