What is the difference between charging and discharging a battery?

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.

What are the challenges associated with fast charging & discharging a battery?

One of the main challenges associated with fast charging and discharging is the degradation of the battery’s electrodes, resulting in decreased battery capacity and increased internal resistance. Rapid charge/discharge rates can also cause high heat generation, leading to thermal runaway and damage to the battery’s electrolyte and electrodes.

How a battery is charged by a DC source?

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.
