Introduction
The lead acid battery is an established energy storage solution widely used due to its reliability and cost-effectiveness. Originating from the work of Gaston Planté in 1859, these batteries have evolved and adapted to meet modern energy storage needs. This article details how lead acid batteries function, their pros and cons, applications, and HRESYS company solutions.
How Lead Acid Batteries Work
Lead acid batteries consist of lead dioxide (PbO2) as the positive plate, sponge lead (Pb) as the negative plate, and a sulfuric acid (H2SO4) electrolyte. The electrochemical process involves the conversion of chemical energy into electrical energy through redox reactions. During discharge, the lead dioxide and sponge lead react with the sulfuric acid to produce lead sulfate (PbSO4) and water (H2O), releasing electrical energy. In the charging phase, the process is reversed, restoring the plates to their original state.
Advantages and Disadvantages
Advantages
- Low cost per watt-hour compared to other technologies.
- Ability to deliver high surge currents.
- Well-established recycling processes.
Disadvantages
- Relatively low energy density (30-50 Wh/kg).
- Limited cycle life (300-500 cycles).
- Requires regular maintenance and can emit hydrogen gas.
Applications of Lead Acid Batteries
Lead acid batteries are used in a variety of applications including automotive starters, uninterruptible power supplies (UPS), and for grid energy storage. Their ability to provide reliable power at a low initial cost makes them a popular choice for emergency backup systems.
