Supplying electrical energy to a battery for it to store energy for later use is called charging. The battery receives the input of electricity causing an electrical current to flow through it hence energy is stored in its cells through some chemical reactions. Discharging a battery occurs when one is using it to power a device or an appliance
Discharge: In contrast, discharge occurs when the stored energy in the battery is released to power external devices or systems. During discharge, the chemical reactions within the battery cause electrons to flow from the negative electrode to the positive electrode through an external circuit, generating electrical current to power the load.

Battery – Principle of operation. The fundamental principle in an electrochemical cell is spontaneous redox reactions in two electrodes separated by an electrolyte, which is a substance that is ionic conductive and electrically insulated. Chemical energy can be stored, for example, in Zn or Li, which are high-energy metals because they are not stabilized by d
Discharge: In contrast, discharge occurs when the stored energy in the battery is released to power external devices or systems. During discharge, the chemical reactions within the battery cause electrons to flow from the negative electrode to the positive electrode through an external circuit, generating electrical current to power the load.
During charging of battery, external DC source is applied to the battery. The negative terminal of the DC source is connected to the negative plate or anode of the battery and positive terminal of the source is connected to the positive plate or cathode of the battery. The external DC source injects electrons into the anode during charging.
The chemical reaction during discharge makes electrons flow through the external load connected at the terminals which causes the current flow in the reverse direction of the flow of the electron. Some batteries are capable to get these electrons back to the same electron by applying reverse current, This process is called charging.
Charging and Discharging Definition: Charging is the process of restoring a battery’s energy by reversing the discharge reactions, while discharging is the release of stored energy through chemical reactions. Oxidation Reaction: Oxidation happens at the anode, where the material loses electrons.
The battery discharge process is analyzed by examining the voltage variation trend of a single discharge curve. In the first stage, the voltage suddenly changes with the discharge current.
One way to efficiently deliver the battery energy to the load when the battery reaches the deeply discharged state is to reduce the system load so that the energy dissipated by the battery internal impedance can be minimized and improve the battery discharge efficiency.
