LiSOCL2 Battery Advantages

1. Stable high working voltage platform

The rated voltage of lithium thionyl chloride battery ( LiSOCl2 battery ) is 3.6V, and the working voltage varies with the load, generally between 3.0V and 3.66V, which is the highest among all single batteries at present. Lithium thionyl chloride batteries are especially suitable for long-term discharge, the load voltage is very stable, and more than 90% of the capacity can be released on a high platform with almost constant voltage.

2. High volume specific energy / high mass specific energy

The mass specific energy is as high as 500WH/Kg, and the volume specific energy is as high as 1000WH/L, which is also the highest among all lithium batteries at present.

3. Longer storage life

The annual self-discharge rate is less than 1% at room temperature, and the storage period can reach 15 years in an environment below 35 °C.

4. Wide operating temperature range

Lithium thionyl chloride batteries ( LiSOCl2 battery ) can be used in extremely harsh environments, conventional batteries can be used in an environment of -55°C~+85°C, and high-temperature batteries can be used in an environment up to 150°C

5. All stainless steel outer body, metal glass sealing structure, non-combustible inorganic electrolyte.
