A lead storage battery is a secondary cell. It is a rechargeable battery that stores electrical energy. When you pass current in the opposite direction, it recharges by reversing the discharge process. Lead storage batteries are widely used in vehicles and backup power systems.
The main function of a lead storage battery is to convert chemical energy into electrical energy during discharge. Conversely, it converts electrical energy back into chemical energy during charging. This process occurs through a series of oxidation and reduction reactions. During discharge, lead dioxide reacts with sulfuric acid, producing lead sulfate and releasing electrical energy. During charging, this transformation is reversed, restoring the original substances.
Lead storage batteries are widely used in various applications, including automobiles, uninterruptible power supplies, and renewable energy storage systems. Their ability to provide a large amount of current and long service life makes them vital in many industries.
In the next section, we will explore the advantages and disadvantages of lead storage batteries, as well as their specific applications in modern technology.
