The chemical reactions are again involved during the discharge of a lead–acid battery. When the loads are bound across the electrodes, the sulfuric acid splits again into two parts, such as positive 2H + ions and negative SO 4 ions. With the PbO 2 anode, the hydrogen ions react and form PbO and H 2 O water. O water.

Taking battery research as an example, we need to know the current status of commercial Li-ion batteries, lead-acid batteries, etc. And then decide what we need in the following …
In 1860, the Frenchman Gaston Planté (1834–1889) invented the first practical version of a rechargeable battery based on lead–acid chemistry—the most successful secondary battery of all ages. This article outlines Planté''s fundamental concepts that were decisive for later development of practical lead–acid batteries.
