Lead-acid batteries are a cornerstone of modern energy storage solutions, playing a crucial role in various industries due to their reliability, affordability, and adaptability. As we delve into the importance of lead-acid batteries, we will explore their applications, benefits, and the ongoing advancements that ensure their relevance in today’s fast-evolving technological landscape.
Understanding Lead-Acid Batteries
Lead-acid batteries are one of the oldest types of rechargeable batteries, invented in 1859 by French engineer Gaston Planté. They consist of lead dioxide (PbO₂) as the positive plate, sponge lead (Pb) as the negative plate, and a sulfuric acid (H₂SO₄) electrolyte. This simple yet effective design enables lead-acid batteries to produce high currents, making them suitable for various applications.
