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 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.
The discharge current is the amount of current drawn from the battery during use, measured in amperes (A). Li-ion cells can handle different discharge rates, but drawing a high current for extended periods can generate heat and reduce the battery’s lifespan.
The external DC source injects electrons into the anode during charging. Here, reduction takes place at the anode instead of the cathode. This reaction allows the anode material to regain electrons, returning to its original state before the battery discharged.
The charging current electrolyzes the water from the electrolyte and both hydrogen and oxygen gas are produced this process called “gassing” of the battery. This gassing raises several problems in the battery. This is unsafe due to the explosive nature of hydrogen produced.
The constant voltage is applied till the current taken by the cell drop to zero, this maximizes the performance of the battery. Charge Termination:- The end of charging is detected by an algorithm that detects the current range that drops to 0.02C to 0.07C or uses a timer method.
