What Is Li-SOCL2 Battery, and What Are the Strengths of Li-SOCL2 Battery?

Lithium Thionyl Chloride (Li-Li/SOCl2) battery is a type of primary battery that uses thionyl chloride as the cathode and lithium as the anode. The ions of a non-rechargeable battery are transported between the anode and the cathode. The Li-SOCL2 battery is widely used in many applications because of its many vital strengths, like high energy density, high capacity, extended lifespan, extended temperature range, low self-discharge rate, etc. Learn about its advantages, application scenarios, product recommendations, and more. 

The Unique Advantages of Li-SOCL2 Batteries

Li-SOCL2 batteries have many key advantages that make them ideal for use in remote applications, harsh environments, and other settings where reliable, long-lasting power is required. Their unique benefits include the following:

1. Greater Energy Density and Higher Capacity

A Li-SOCL2 battery offers excellent performance because of its high energy density. As commercial application batteries, they also have a higher capacity, making them suitable for many applications.

2. Extended Temperature Range

The temperature range of a Li-SOCL2 battery is -55°C to 85°C, which is very high compared to many other types, making it suitable for use in harsh environments.

3. Long Long Shelf Life

Li-SOCL2 batteries have a long lifespan, reaching a very long shelf life that is more than 10 to 15 years, making them suitable for long-term storage and use in many applications.

4. Higher Operating Voltage

The Li-SOCL2 batteries have high cell voltages (nominal voltage 3 .6V) and energy densities of the practical battery systems. Long shelf life and operation life, wide operation temperature range, and flat operation voltage plateau make it the best choice for multiple utilization, especially IoT devices.

5. Low Self-Discharge Rate

Li-SOCl2 batteries can remain unused for a long time without draining too quickly due to self-discharge. Their low self-discharge rate makes them suitable for applications that require long-term battery life, e.g., data loggers, remote sensors, etc.
