Question: Briefly describe the difference between charging and discharging in a lithium-ion battery.

Charging and discharging in a lithium-ion battery involve the movement of lithium ions and electrons through the battery's internal structure. During charging, an external power source forces lithium ions to move from the cathode to the anode, where they are stored in the graphite layer. This process involves the flow of electrons in the opposite direction through the external circuit, which charges the battery. Conversely, during discharging, the stored lithium ions move back from the anode to the cathode, releasing the stored energy as electrons flow through the external circuit to power a device. The movement of ions and electrons during both processes is facilitated by the electrolyte, which is a conductor of ions but an insulator of electrons. This dual-path movement is crucial for the battery's ability to store and deliver energy efficiently.
