Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current. This point is commonly referred to as the “charging cut-off current.” II. Key Parameters in Lithium-ion Battery Charging
Charging a lithium-ion battery involves precise control of both the charging voltage and charging current. Lithium-ion batteries have unique charging characteristics, unlike other types of batteries, such as cadmium nickel and nickel-metal hydride.
This means that during the charging and discharging process, the lithium ions move back and forth between the two electrodes of the battery, which is why the working principle of a lithium-ion battery is called the rocking chair principle. A battery typically consists of two electrodes, namely, anode and cathode.
Going below this voltage can damage the battery. Charging Stages: Lithium-ion battery charging involves four stages: trickle charging (low-voltage pre-charging), constant current charging, constant voltage charging, and charging termination. Charging Current: This parameter represents the current delivered to the battery during charging.
Standard Charging: Using a standard charger that supplies a typical current (usually around 0.5C to 1C, where C is the battery’s capacity), it takes approximately 2 to 3 hours to charge a Li-ion cell from 0% to 100%. Fast Charging: Some modern chargers can supply higher currents (above 1C), reducing charging time to as little as 1 hour.
Frequent Charging: To extend the life of lithium-ion batteries, they should be charged before reaching a low state of charge, ideally when they’re at around 80% capacity. Avoid allowing them to fully discharge before recharging. Proper Storage: When not in use, lithium-ion batteries should not be left in a discharged state.
