I’ve long been interested in energy storage, so the distinctions between lead-acid and lithium batteries have always piqued my curiosity.Both battery technologies have been around for a while, but they differ in important ways. In this article, I will explain the main differences between the two types of batteries and discuss the advantages and disadvantages of each.
The earliest and best-known form of rechargeable battery is the lead-acid battery, which is currently utilized in a variety of applications. A lead-acid battery has two electrodes—a positive electrode and a negative electrode—that are submerged in an electrolyte solution. The negative electrode, composed of lead, turns into lead oxide when the battery is charged, while the positive electrode, consisting of lead dioxide, turns into lead sulfate.When the battery is discharged, the chemical reaction is reversed, and the lead sulfate and lead oxide are converted back into lead dioxide and lead, respectively.
