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.
Lead–acid batteries were used to supply the filament (heater) voltage, with 2 V common in early vacuum tube (valve) radio receivers. Portable batteries for miners' cap headlamps typically have two or three cells. Lead–acid batteries designed for starting automotive engines are not designed for deep discharge.
Implementation of battery man-agement systems, a key component of every LIB system, could improve lead–acid battery operation, efficiency, and cycle life. Perhaps the best prospect for the unuti-lized potential of lead–acid batteries is elec-tric grid storage, for which the future market is estimated to be on the order of trillions of dollars.
Nevertheless, forecasts of the demise of lead–acid batteries (2) have focused on the health effects of lead and the rise of LIBs (2). A large gap in technologi-cal advancements should be seen as an opportunity for scientific engagement to ex-electrodes and active components mainly for application in vehicles.
This comes to 167 watt-hours per kilogram of reactants, but in practice, a lead–acid cell gives only 30–40 watt-hours per kilogram of battery, due to the mass of the water and other constituent parts. In the fully-charged state, the negative plate consists of lead, and the positive plate is lead dioxide.
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 use in motor vehicles to provide the high current required by starter motors.

Flooded Lead Acid vs. Lead-Calcium Batteries
Lead-calcium batteries are a type of sealed, maintenance-free battery that uses lead-calcium alloy instead of lead-antimony alloy in the battery plates. The lead-calcium alloy is used in both the positive and negative plates of the battery. This combination results in a battery that is more resistant to corrosion and has a longer service life compared to traditional lead …

The lead–acid cell can be demonstrated using sheet lead plates for the two electrodes. However, such a construction produces only around one ampere for roughly postcard-sized plates, and for only a few minutes. Gaston Planté found a way to provide a much larger effective surface area. In Planté''s design, the positive and negative plates were formed of two spirals o…

BU-201: How does the Lead Acid Battery Work?
The grid structure of the lead acid battery is made from a lead alloy. Pure lead is too soft and would not support itself, so small quantities of other metals are added to get the mechanical strength and improve electrical properties. The most common additives are antimony, calcium, tin and selenium. These batteries are often known as "lead-antimony" and "leadcalcium." Adding ...

How Does Lead-Acid Batteries Work?
Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery''s capacity and eventually rendering it unusable. Desulfation is the process of reversing sulfation …
