Self-discharge is a phenomenon in batteries. Self-discharge decreases the shelf life of batteries and causes them to have less than a full charge when actually put to use. How fast self-discharge in a battery occurs is dependent on the type of battery, state of charge, charging current, ambient temperature and other factors.
Self-discharge can significantly limit the shelf life of batteries. The rate of self-discharge can be influenced by the ambient temperature, state of charge of the battery, battery construction, charging current, and other factors. Primary batteries tend to have lower self-discharge rates compared with rechargeable chemistries.
Self discharge of cells is dependent on the chemistry, temperature and age of the cell. These reactions occur in any electrochemical systems and are very difficult to avoid completely. This is because some self discharge reactions involve chemical reactions which will always take place at a rate proportional to temperature.
Primary batteries are not designed for recharging between manufacturing and use, and thus to be practical they must have much lower self-discharge rates than older types of secondary cells. Later, secondary cells with similar very low self-discharge rates were developed, like low-self-discharge nickel–metal hydride cells.
Self-discharge is a chemical reaction, just as closed-circuit discharge is, and tends to occur more quickly at higher temperatures. Storing batteries at lower temperatures thus reduces the rate of self-discharge and preserves the initial energy stored in the battery.
The rationality of applying the Evans Diagram to self-discharge batteries is adequate. In essence, as summarized in Table 2, both corrosion of metals and self-discharge of batteries are irreversible electrochemical reactions on a certain interface. Table 2.
