What is self-discharge in a primary lithium battery? motion design part 2

The self-discharge phenomenon which leads to a loss of the battery's capacity is intrinsic to any electro-chemical system. It is an internal chemical reaction consuming anode and cathode materials that occurs during storage but also, while in use.

Self-discharge is an important factor to consider for IoT applications, as the IoT devices must operate for several years with a single battery.

Watch our video to find out about the two self-discharge phenomena that can impact battery life, which factors are accelerating them and how to anticipate it to avoid battery lifetime calculation errors.

This video is part of a series of 4 videos that explain the basic functioning of a primary lithium battery, and the main chemical reactions that occur in a Lithium Thionyl Chloride battery.
