irinina [24]

Rechargeable batteries use a reversible reaction medium to convert electrical current to a form of chemical energy which can be stored for future use.

<h3>What is a rechargeable battery?</h3>

A rechargeable battery is a type of battery that can be charged many times by passing electric current through the cells in a reversible reaction.

<h3>How does recahargeable battery store energy?</h3>

When electrical energy from an outside source is applied to a secondary cell (reachargeable battery), the negative to positive electron flow that occurs during discharge is reversed, and the cell's charge is restored. This process is called reversible reaction.

Thus, rechargeable batteries use a reversible reaction medium to convert electrical current to a form of chemical energy which can be stored for future use.
