Self-discharge
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. Primary batteries are not designed for recharging between manufacturing and use, and thus to be practical they must have much lowe

Explained: What Causes Battery Self-Discharge
High temperatures accelerate chemical reactions, leading to increased self-discharge, while lower temperatures slow down the process. However, extremely low temperatures can also reduce battery performance. Understanding the
6 FAQs about [Battery self-discharge at high temperature]
What causes a battery to self-discharge at a high temperature?
Self-Discharge: High temperatures can accelerate the self-discharge rate of batteries. Self-discharge occurs even when the battery is not in use, and is typically caused by internal chemical reactions. At high temperatures, these reactions occur at a faster rate, leading to a quicker depletion of the battery’s stored charge. 2.
How does self-discharge affect the shelf life of batteries?
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.
Why do batteries self-discharge?
Self-Discharge is Inevitable in All Batteries: Self-discharge is a natural phenomenon where batteries lose their charge over time even when not in use. This occurs due to internal chemical reactions within the battery, and the rate of self-discharge varies depending on the battery type and environmental conditions.
Why do batteries need to be stored at lower temperatures?
Storing batteries at lower temperatures thus reduces the rate of self-discharge and preserves the initial energy stored in the battery. Self-discharge is also thought to be reduced as a passivation layer develops on the electrodes over time.
How does temperature affect lithium ion batteries?
Excessive temperatures also cause the solid electrolyte interface (SEI) to deteriorate, further increasing self-discharge and loss of lithium. Moisture causes an electrolytic imbalance in the battery resulting in higher self-discharge rates.
What factors affect battery self-discharge rate?
Self-discharge rates can vary considerably for different battery chemistries (Table: Wikipedia ). 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.
