Lithium ion batteries mainly rely on the movement of lithium ions between the positive and negative electrodes to achieve the charging and discharging process. During charging, lithium ions are released from the positive electrode material and embedded into the negative electrode material through the electrolyte; When discharging, the opposite is true. Lithium ions return from the negative electrode to the positive electrode, and electrons move in the external circuit to form an electric current, providing electrical energy to the device.
Performance characteristics: high energy density, high voltage platform, low self discharge rate, long cycle life.
