What Is a Lead Acid Battery and How Does It Work?
A lead-acid battery is a type of rechargeable battery that uses lead dioxide and sponge lead as electrodes, with sulfuric acid as the electrolyte. This battery converts chemical energy into electrical energy through electrochemical reactions.
According to the Battery University, lead-acid batteries are “the oldest rechargeable battery technology” and are widely used in vehicles and backup power systems. They offer a reliable source of power due to their well-established technology and effectiveness.
Lead-acid batteries function by undergoing reversible reactions between lead, lead dioxide, and sulfuric acid. During discharge, lead sulfate forms, releasing electrical energy. When recharged, these substances convert back to their original forms, allowing for repeated use.
The U.S. Department of Energy states that “lead-acid batteries are the most recycled consumer product” in the country, with up to 99% of the materials recoverable. This contributes to a circular economy, where materials are reused instead of discarded.
Factors affecting lead-acid battery performance include temperature, charge cycles, and maintenance. Higher temperatures can accelerate degradation, while poor maintenance can lead to sulfation, reducing capacity and lifespan.
Lead-acid batteries account for about 40% of the global battery market, according to a report by Grand View Research, Inc. The market is projected to grow steadily over the next decade as demand for renewable energy storage increases.
The use of lead-acid batteries raises environmental concerns due to potential lead contamination. Poor disposal methods can harm ecosystems and human health. Addressing these issues requires effective recycling programs and adherence to environmental regulations.
