The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents. These features, along with their low cost, make them attractive for u
Charge and discharge principle of lead-acid battery In the process of discharge, because O24 is a strong electrolyte, it exists in the form of H and 2 SO 4 conductor between the positive and negative plates, the battery will be short-circuited and the overall voltage will drop. Open circuit means that the circuit connection is interrupted

Key learnings: Lead Acid Battery Definition: A lead acid battery is defined as a rechargeable battery that uses lead and sulfuric acid to store and release electrical energy.;
When the lead-acid battery is fully charged, the material on the positive electrode plate is lead dioxide (PbO2), the material on the negative plate is fluffy lead (Pb), and the density of electrolyte sulfuric acid (H2SO4) is about 1.33 g/cm3 (refers to Lead-acid batteries for electric vehicles, the density of lead-acid batteries for other uses is slightly lower).
A lead acid battery has lead plates immersed in electrolyte liquid, typically sulfuric acid. Understanding these fundamental aspects is essential since they demonstrate the basic principles behind the operation of lead acid batteries. serves as the medium that facilitates ion exchange between the positive and negative plates. Sulfuric
In principle, this requires: (1) adequate provision of acid; (2) which has one lead–dioxide positive plate and one sponge-lead negative plate, A typical lead–acid battery will exhibit a self-discharge of between 1% and 5% per month at a temperature of 20°C. The discharge reactions involve the decomposition of water to form hydrogen
From the above chemical reaction equation, it can be seen that when the lead-acid battery is discharging, the active material lead dioxide of the positive electrode and the active material lead metal of the negative electrode react with the sulfuric acid electrolyte to form lead sulfate, which is called "bisulfate reaction" in electrochemistry.
The negative plate is made up of lead and the positive plate of lead dioxide in the fully charged state. Concentrated sulphuric acid is the electrolyte, which retains most of the chemical energy.
In a lead-acid cell the active materials are lead dioxide (PbO2) in the positive plate, sponge lead (Pb) in the negative plate, and a solution of sulfuric acid (H2SO4) in water as the electrolyte.
