Lead 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.

The storage requirements of lithium-ion batteries differ from lead-acid batteries due to their higher energy density, longer cycle life, and greater efficiency. These factors contribute to their widespread use in various applications, including portable electronics, electric vehicles, and grid-scale energy storage.
Efficiency. Lead–acid batteries typically have coulombic (Ah) efficiencies of around 85% and energy (Wh) efficiencies of around 70% over most of the SoC range, as determined by the details of design and the duty cycle to which they are exposed. The lower the charge and discharge rates, the higher is the efficiency.
Deep-cycle lead-acid batteries appropriate for energy storage applications are designed to withstand repeated discharges to 20 % and have cycle …
Early lead-acid batteries could expand the voltage window to 2 V, achieving a further increase in energy density. However, this is well below the voltage range involved in nonaqueous batteries. Therefore, it may be considered to expand the voltage window through the introduction of polyethylene glycol (PEG)-based aqueous …

To put it simply, lead-acid batteries generate electrical energy through a chemical reaction between lead and sulfuric acid. The battery contains two lead plates, one coated in lead dioxide and the other in pure lead, submerged in a solution of sulfuric acid. When the battery is discharged, the sulfuric acid reacts with the lead to create lead ...
