Yet unrivalled battery life - Li-SoCl2 batteries from EVE

Lithium-thionyl chloride cells (Li-SoCl₂) 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 batteries are the non-chargeable primary batteries with the highest voltage and energy, longest storage, and the least self-discharge rate. These batteries are ideal for such long-term applications as power source for electronic devices and AMR (water, heat and gas meters), and especially as a backup power source for memory ICs.

Product features:

• 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.

• Wide operating temperature range: The battery is capable of operation in a wide temperature range, normally from -60°C to +85°C. Even special version with an extended temperature range up to +150°C is available.

• High energy density: The electrochemical system exhibits the highest energy density of any available primary battery, up to 650Wh/kg and 1280Wh/L.

• Long operating life and superior shelf life: The self-discharge of Li/SOCl₂ battery is extremely low (less than 1% per year at 20°C), which results in a long storage periods and a service life of up to 10-20 years.

• Excellent safety: The complete line of products is recognized and regularly supervised by Underwriters Laboratories, and meet UN transportation test requirements.

• 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.
