Lithium Thionyl Chloride batteries are used in many IoT applications and knowing how they work and their particularities will help you select the best options for your application, and understand what to take into consideration when calculating your device’s lifetime in the field.

With that in mind, we have created a series of 4 videos that explain the basic functioning of a primary battery, and the main chemical reactions that occur in a Lithium Thionyl Chloride battery.

In the first one, “How does a primary Lithium Thionyl Chloride battery works”, you will find out about the anatomy of a battery, how stored chemical energy is converted to electrical energy, the particularities of Lithium Thionyl Chloride systems in terms of operating voltage, and how the battery discharges itself and eventually dies.

In the 2nd and 3rd videos, we’ll assess two phenomena that can impact the life duration of a Lithium Thionyl Chloride battery: the self-discharge and, in the case of a liquid cathode system, the passivation.

In the final video, we’ll see how these two phenomena, self-discharge and passivation impact IoT applications.

We hope that after watching the videos, you’ll feel more clued up about Lithium Thionyl Chloride batteries in IoT applications, but if you have any additional questions, please drop us an email at energizeIoT@saftbatteries.com and we’ll be happy to answer it.
