The voltage remains constant while the current gradually decreases as the battery approaches full charge. Charging is considered complete when the current drops to a minimal level. 3. Charging Safety Safety is paramount when charging lithium batteries.
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
This point is commonly referred to as the “charging cut-off current.” II. Key Parameters in Lithium-ion Battery Charging Several crucial parameters are involved in lithium-ion battery charging: Charging Voltage: This is the voltage applied to the battery during the charging process.
The standard regimen for charging lithium-ion cells is CCCV charging. The charging DC source is set to the desired charging current rate and voltage level set to equal to the cell’s fully charged voltage. This gives a rectangular I-V characteristic plot for the positive quadrant, like that previously shown in Figure 1, now shown in Figure 3.
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.
During the initial CC phase, the cell is charged with constant current up to its maximum voltage. At that point, the charging automatically transitions to CV phase, where the balance of charging takes place, bringing the cell up to 100% SoC. Conversely, the standard discharging regimen for lithium-ion cells uses only CC operation.

Once the battery reaches that voltage level ...
The major source of positive lithium ions essential for battery operation is the dissolved lithium salts within the electrolyte. The movement of electrons between the negative and positive current collectors is facilitated by their migration to and from the anode and cathode via the electrolyte and separator (Whitehead and Schreiber, 2005).
