How Does Lead-Acid Batteries Work?

The lead sulfate at the positive electrode is converted back into lead dioxide, and the lead sulfate at the negative electrode is converted back into lead. This process releases electrons, which flow through the external circuit and power the device. The chemical reactions that occur in a lead-acid battery can be summarized as follows: At the positive electrode: …

Lead Acid Battery

The lead-acid battery consists negative electrode (anode) of lead, lead dioxide as a positive electrode (cathode) and an electrolyte of aqueous sulfuric acid which transports the charge between the two. At the time of discharge both electrodes consume sulfuric acid from the electrolyte and are converted to lead sulphate. While recharging the lead sulphate is …

Lead–Acid Batteries

For example, the grid in lead–acid batteries is made of solid lead and the active mass, a sponged lead for the negative electrode is pressed into the grid. The grid itself is maybe only partially exposed to electrolyte and it mainly serves as the mechanical support for the active mass and as a current collector. Over time, however, the lead in the grid slowly gets …
