In reaction to the above requirements and concerns, improvements in the lead–acid battery era have been developed, such as the incorporation of carbon to the negative active mass and positive active mass of batteries, as well as the use of carbon in current collectors and negative electrodes.
Abstract. The traditional methods of charging lead-acid batteries depend on stabilizing the current or voltage through simple electronic circuits, which causes the shorten the life of the batteries due to damage to the electrodes or the hot and dry batteries.
Charging of lead–acid cell Discharging of a lead–acid cell The chemical reaction takes place at the electrodes during charging. On charge, the reactions are reversible. When cells reach the necessary charge and the electrodes are reconverted back to PbO 2 and Pb, the electrolyte's specific gravity rises as the sulfur concentration is enhanced.
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.
According to recent research, the failure mode of lead–acid batteries is PAM weakening and shedding, and the battery lifespan is primarily confined to the positive electrode. As a consequence, the lead–acid battery has hit a stumbling block that must be addressed to improve the PAM of the lead–acid battery's efficiency.
Lead–acid batteries' long-term sustainability is often questioned. Many have claimed that only the lead–acid battery has no future, but this is nothing new, and amid decades of predictions to the contrary, the lead–acid battery continues to dominate the global battery energy storage market.
Formation is one of the critical steps in lead acid battery manufacturing process. The purpose of the formation step is to convert the cured pastes into electrochemically active porous materials
The manufacturing process of lead acid batteries is also characterized by the long lead-time before it reaches the assembly line. This lead time is some time due to necessary process such as requirement of grid cell hardening, formation, and washing and drying (For more detail on the manufacturing process before reaching the assembly line see Elimam, and Udayabhanu .
Lead-acid batteries are the oldest type of rechargeable battery and have been widely used in many fields, such as automobiles, electric vehicles, and energy storage due to the features of large power-to-weight ratio and low cost (Kumar, 2017).

The lead acid battery uses the constant current constant voltage (CCCV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries. With higher charge currents and multi-stage
