Saft Primary Lithium-thionyl chloride (Li-SOCl2)
  • Lithium-thionyl chloride cells have a metallic lithium anode (the lightest of all the metals) and a liquid cathode comprising a porous carbon current collector filled with thionyl chloride (SOCl2). They deliver a voltage of 3.6 V and are cylindrical in shape, in 1/2AA to D format, with spiral electrodes for power applications and bobbin construction for prolonged discharge.

  • Lithium-thionyl chloride cells have a high energy density, partly because of their high nominal voltage of 3.6 V. Bobbin versions can reach 1220 Wh/L and 760 Wh/kg, for a capacity of 18.5 Ah at 3.6 V in D format. Because self-discharge is extremely low (less than 1% per year), this kind of cell can support long storage periods and achieve a service life of 10 to 20 years.

  • For different applications, the cells can be fitted with various types of connectors and assembled in various battery arrays, including a number of standardized versions.

  • Saft products address a broad spectrum of fixed and mobile civil and defence applications.


As of September of 2009 Saft has combined the LS, LST and LSG cell series and these products will now be labeled as the LS Series.

Also, Considering the narrow performances reached between the new generation of these standard cells compared to the C version, the LS 14250 and the LS 14500 cells in their new generation appear as the natural successor of the current C version.
