Lithium Thionyl Chloride Battery

3.6 Volt Primary / Non-Rechargeable Battery

 Main Features  

  • The Li-SoCl2 batteries have the highest energy density of any practical Lithium battery chemistry.  Its energy density is 3 times higher than Alkaline batteries.
  • The nominal voltage of Lithium Thionyl Chloride (Li-SOCl2) battery is 3.6V
  • The Bobbin Energy Type of Li-SOCl2 battery is best suited for low current discharge profile applications. Spiral High Power Type and  Li-SOClER+Li-Capacitor High Power Pack version is best suited for high current peak discharge profile applications. 
  • Very wide temperature range: -55 °C ~ +85 °C. 
  • Superior shelf life: The self discharge EEMB Li-SOClBattery is extremely low, which can support long storage periods and achieve storage life of 10+ years.
  • Lithium Thionyl Chloride (Li-SOCl2) battery is a non-rechargeable (primary) lithium battery.  

                *The battery cannot be recharged.

Principle and Reactions:

The positive active material of Li-SOCl2 batteries is liquid Thionyl Chloride (SOCl2) and the negative active material is Lithium (Li). The reactions of the batteryare shown below:

Positive reaction:   2SOCl2 + 4Li+ + 4e- →4LiCl + S + SO2

Negative reaction:   Li → Li+ + e-

Complete reaction:   2SOCl2+4Li → 4LiCl+ S + SO2

  Main Applications  

Smart Utility Metering/Emergency Backup/Data Collection/Unattended Sensors/RFID Tracking/Asset Tracking/Theft Prevention/Hunting Dogs/Carbon Monoxide Detectors/Gas/Water/Electric Meter/Toll RFID/IoT/Movement Sensor Monitor/Home Security System/Alarm System
