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. The PbO begins to react with H 2 SO 4 and

Customer ServiceBatteries are perhaps the most prevalent and oldest forms of energy storage technology in human history. 4 Nonetheless, it was not until 1749 that the term "battery" was coined by Benjamin Franklin to describe several capacitors (known as Leyden jars, after the town in which it was discovered), connected in series. The term "battery" was presumably chosen

Customer ServiceLead batteries operate in a constant process of charge and discharge When a battery is connected to a load that needs electricity, such as a starter in a car, current flows from the battery and the battery then begins to discharge. As a battery begins to discharge, the lead plates become more alike, the acid becomes weaker and the voltage drops.

Customer ServiceIn the case of valve-regulated lead-acid batteries (VRLA), carbon can be oxidized by oxygen transported from positive plates, which prevents recombination of this gas with hydrogen and increases the loss of water and additionally lowers the beneficial effect of this additive on the charge acceptance .
Carbon can also be used in the battery construction as a capacitor electrode allowing them to achieve a higher power density. Spread of mentioned carbon-based improvements in the lead-acid battery construction can lead to many further years of the economically feasible use of this type of batteries.
In the last 160 years, many applications have been found and they are still in a widespread use, e.g., as car batteries or a backup power. The lead-acid battery is a secondary cell, where during a discharge, it produces lead (II) sulfate (IV) from a metallic lead (on the negative electrode) and from lead (IV) oxide (on the positive electrode).
Lead-acid batteries are still promising as ener- gy sources to be provided economically from worldwide. From the issue of resources, it is the improvement of the lead-acid battery to support a wave of the motorization in the developing countries in the near future.
The recovery of lead acid batteries from sulfation has been demonstrated by using several additives proposed by the authors et al. From electrochemical investigation, it was found that one of the main effects of additives is increasing the hydrogen overvoltage on the negative electrodes of the batteries.
In addi- tion, from an environmental problem, the use of the lead- acid batteries to the plug-in hybrid car and electric vehi- cles will be possible by the improvement of the energy density. References
