reversible cell

A reversible cell, often called a rechargeable battery, is a device that stores electrical energy during charging and releases it when in use. Unlike disposable batteries, which can only be used once, reversible cells can go through multiple cycles of charging and discharging without significant loss of performance. This is possible because the chemical reactions inside the cell can be reversed, restoring the materials to their original state. Common examples include smartphone batteries and electric vehicle batteries, enabling sustainable and convenient energy use for various applications.
