Lithium-Thionyl Chloride Batteries

Li-SOCl2 batteries (Lithium-Thionyl Chloride) are primary cells, that means NOT rechargeable.
They have been developed in the United States in the late 50s mainly for military and aerospace applications.
As a result, the development has been directed toward civilian use, thanks to the higher performances compared to existing cells.

They have a nominal voltage of 3.6 V (OCV 3.67 V) and an energy density till 650 Wh / kg.

Other important features:
- Low self-discharge: 3% the first year, then 1% per year
- Wide temperature range: from -60 ° C to +150 ° C depending on the construction technology
- They are completely hermetic, thanks to the glass-to-metal sealing
- Stainless steel case
- Available in battery packs or with different types of tabs
- UL certificated

They are manifactured in 2 construction technologies:
- bobbin, with high capacity and low current discharge
- spiral, for high discharge currents and lower capacity.

NRG distributes the widest range of Lithium-thionyl chloride batteries available, in the following shapes:
- cylindrical
– prismatic
– button

Safety Note: Li-SOCl2 spiral batteries distributed by NRG are equipped with a fuse to protect against short circuits and with a patented particular system of closure of the negative pole that allows venting of any gas caused by malfunction, preventing explosions.
