High Temperature Lithium Thionyl Chloride Battery
High Temperature Lithium Thionyl Chloride Battery use lithium metal as the anode and thionyl chloride (SOCl2) as the cathode. This unique combination is key to their long life. Lithium is highly reactive and has a high energy density, which means it can store a lot of energy. Thionyl chloride is also very reactive, and it helps create a stable chemical reaction that efficiently generates electricity.

Features of High Temperature Lithium Thionyl Chloride Battery
01/
High cell voltage : The battery has an open-circuit voltage of 3.67V and an operating voltage of 3.60V, which are considerably higher than in any other commercially available primary batteries.
02/
Wide operating temperature range : The battery is capable of operation in a wide temperature range normally from -60℃ to +85℃. One special series has an extended temperature range up to 150°C.
03/
High energy density : The electrochemical system exhibits the highest energy density of any available primary battery, up to 650Wh/kg and 1280Wh/L.
04/
Long operating life and superior shelf life : The self-discharge of Li/SOCl2 battery is extremely low (less than 1% per year at 20℃), which can support long storage periods and achieve a service life of 10 to 20 years.
05/
Excellent safety : The complete line of products is recognized and regularly inspected by Underwriters Laboratories, and meet UN transportation test requirements.
06/
Hermetically sealed case : The hermetically sealed case is essential for the long shelf life and inherent safety of the devices in which the batteries are used. The cover is welded to the can. A glass-to-metal seal is used to insulate the positive terminal. A safety vent is used on the negative terminals for spiral type.
Advantages of High Temperature Lithium Thionyl Chloride Battery
Chemical Stability for Longevity
One major reason for the long life of lithium-thionyl chloride batteries is their chemical stability. The reaction between lithium and thionyl chloride is very stable over time. This stability means that the battery can retain its energy for a long time without degrading.
Low Self-Discharge Rate
Lithium-thionyl chloride batteries have a very low self-discharge rate. Self-discharge refers to the loss of charge that happens even when the battery is not in use. In most batteries, this rate can be quite high, leading to a loss of power over time.
Efficient Energy Storage
The design of lithium-thionyl chloride batteries allows for efficient energy storage. The high energy density of lithium means that these batteries can store a large amount of energy in a small space. This compact design helps maintain their efficiency over time.
Temperature Range and Environmental Factors
Another factor contributing to the long life of lithium-thionyl chloride batteries is their ability to operate across a wide temperature range. These batteries can function well in both high and low temperatures.
Applications That Benefit from Long Life
Many applications benefit from the long life of a lithium-thionyl chloride battery. For instance, they are used in remote sensors that are difficult to access. Because these sensors need to operate continuously without regular maintenance, the long-lasting power of these batteries is crucial.
Type of High Temperature Lithium Thionyl Chloride Battery
Low discharge rate batteries: Used in metering instruments such as CMOS memory and water/gas meters, with a lifespan of over 10 years.
High discharge rate batteries: Employ a wound structure to meet the instantaneous high current requirements of military laser guns, radar, and other applications.
Applications of High Temperature Lithium Thionyl Chloride Battery
Space navigation systems
Serving as the main power source, they meet the standby requirements for satellites operating in long-term orbits for over 10 years.
01
Oil drilling
Downhole telemetry equipment utilizes its high-temperature products, enabling continuous operation in high-temperature environments.
02
Military field
Military sonar buoys leverage their cryogenic start-up capability and ultra-low self-discharge rate to ensure deep-sea monitoring cycles of up to 10 years. Additionally, military equipment such as laser guns, radars, and electronic sights also use lithium thionyl chloride batteries as their power source.
03
Medical equipment
Various mobile medical devices, ballasts, and equipment used in applications such as conditioning systems, endoscopes, electric fields, X-ray imaging, and electroencephalography (EEG) systems all utilize lithium thionyl chloride batteries as their power source.
04

Such as smart meters and water meters, they utilize the high energy density and long lifespan of lithium thionyl chloride batteries to achieve long-term stable opera
05
Working Principle of High Temperature Lithium Thionyl Chloride Battery
During discharge, a lithium thionyl chloride battery releases electrons from the lithium anode. These electrons flow to the cathode and react with the thionyl chloride on the cathode, producing lithium ions, lithium chloride, sulfur, and sulfur dioxide. The overall reaction equation is: 4Li + 2SOCl → 4LiCl + S + SO₂. Sulfur and sulfur dioxide dissolve in the excess thionyl chloride electrolyte, while lithium chloride is insoluble and deposits on the cathode.
Safety Precautions
Do Not Charge: Lithium thionyl chloride batteries are disposable and must not be charged. Charging will cause uncontrollable chemical reactions inside the battery, potentially leading to explosion or fire.
Prevent Short Circuit:Never short circuit the battery. Avoid direct contact between the positive and negative terminals and a metal conductor to prevent the generation of a large current inside the battery, which could cause a safety accident.
Prevent Over-Discharge:Never over-discharge the battery. Once the battery has discharged to its termination voltage (e.g., 2.0V), stop using it immediately to prevent damage to the internal structure.
Avoid High Temperatures: Batteries may explode in high-temperature environments. Therefore, avoid using or storing the battery in high-temperature environments.
Correct Installation and Use: The battery should be installed with the positive terminal horizontal and facing upwards. If the positive terminal is downwards, some of the capacity will be unusable.
