Introduction
This video explains the working principle of a lithium-ion battery, a popular type of battery used in electric vehicles. It uses a simplified model to illustrate the processes during charging and discharging.
Key Takeaways
Simplified Lithium-ion Battery Structure: The video describes a simplified lithium-ion battery cell composed of a graphite anode, a lithium metal oxide cathode, an electrolyte, and a separator (polypropylene/polyethylene).
Charging Process: During charging, a current is applied between the electrodes. Lithium ions move from the cathode to the anode, combining with carbon to form lithium carbide. Electrons flow in the opposite direction.
Discharging Process: During discharging, the process reverses. Lithium ions are released from the anode and travel through the electrolyte to the cathode, combining with the lithium metal oxide. Electrons flow through the external circuit.
