Discharging process: In contrast, during discharging, the stored chemical energy is converted back into electrical energy. The electrons flow from the negative terminal to the positive terminal. This occurs as the chemical reactions reverse, releasing energy for use. Research by G. Wang and S. Li (2020) indicates that effective management of the discharging process can significantly extend battery life and improve overall performance.
-
Independent operation: These processes operate independently because charging and discharging can happen at different times or under different conditions. For example, a battery may be charged overnight while a device is not in use, and then discharging occurs when the device is turned on. The independence allows devices like smartphones and laptops to function continuously, as they can charge when plugged in and discharge while in use.
