Overview Properties/Characteristics of Battery -Type ER The thionyl chloride lithium battery is constructed from inorganic materials. This innovative design allows it to be used much longer than conventional batteries, which contained organic compounds in some locations. This battery is ideal for such long-term applications as power for electronic devices and electric power, water, and gas meters, and especially as a backup power source for memory ICs. Construction
Principle and Reactions The thionyl chloride lithium battery uses liquid thionyl chloride (SOCL2) as its positive active material, and lithium (Li) as its negative active material. This battery is constructed entirely of inorganic materials. The reactions of the battery are shown below. Battery Reactions Positive reaction:
2SOCl2+4Li + -> 4LiCl+S+SO2 Negative reaction: Li -> Li++eTotal reaction: 2SOCl2+4Li -> 4LiCl+S+SO2
Features High 3.6-V voltage The thionyl chloride lithium battery achieves a high voltage of 3.6 V. Flat discharge characteristics The change of internal resistance during discharge is minimal, allowing for flat discharge voltage until end of discharge life.

Wide usable temperature range Can be used over a wide temperature range : - 55 deg. C to +85 deg. C (please consult with Maxell if using in temperatures of -40 deg. C or less). Superior long-term reliability The extremely low self-discharge, together with the use of a hermetic seal, allows for stable use over long periods. UL (Underwriters Laboratories Inc.) recognized component Applications Backup power for memory ICs / power source for water, electricity, gas, and other meters / power source for theft and other alarm systems / power source for space, aeronautics, sea, underground resource development, and other special applications / power source for sensors / power source for measuring devices Minimum Transient Voltage The thionyl chloride lithium battery has remarkably lower selfdischarge when compared with conventional batteries. This is because a lithium chloride membrane is formed over the negative lithium surface, blocking reaction with the positive material. When first discharging after storage, resistance from this lithium chloride membrane may temporarily reduce the voltage at the initiation of discharge. The lowest voltage at this time is called minimum transient voltage, and the lower the temperature, and the larger the discharge current, the lower the voltage will be. Because minimum transient voltage is greatly influenced by storage time and conditions, it is necessary to take this into sufficient consideration when designing a device.

The figure above shows minimum transient voltage using a fresh battery.
Relationship between Discharge Load and Operating Voltage The operating voltage of a battery falls as the discharge load increases and temperature falls. In the case of initial use, an electric potential of at least 3 V will be maintained even at temperatures of 40 deg. C at discharge of less than 1 mA.
Storage Characteristics The thionyl chloride lithium battery is made from chemically stable inorganic materials. Additionally, a sealing method employing a laser-welded seal structure and hermetic seal hinders the admittance of outside air. These features provide superior storage characteristics, holding down self-discharge to no more than 1% of capacity per year at normal temperatures.
