When the cells are assembled as a battery pack for an application, they must be charged using a constant current and constant voltage (CC-CV) method. Hence, a CC-CV charger is highly recommended for Lithium-ion batteries. The CC-CV method starts with constant charging while the battery pack’s voltage rises.
Hence, a CC-CV charger is highly recommended for Lithium-ion batteries. The CC-CV method starts with constant charging while the battery pack’s voltage rises. When the battery reaches its full charge cut-off voltage, constant voltage mode takes over, and there is a drop in the charging current.
At low temperature, lithium-ions diffuse more slowly in the electrode and electrolyte, and the intercalation dynamics are slow. In this case, the continuous charging of the battery will lead to a rapid decline in capacity, seriously limiting the application of LIBs .
Charging the battery forces the ions to move back across the electrolyte and embed themselves in the negative electrode ready for the next discharge cycle (Figure 1). Figure 1: In a Li-ion battery, lithium ions move from one intercalation compound to another while electrons flow around the circuit to power the load. (Image source: DigiKey)
It's also crucial to keep the cell voltage above 2.4 or 2.5 V during discharge; else, the cell's life would be severely harmed. The word 'Ion' existing with the battery's name merely means that Lithium must never be encountered in its metallic form in the battery.
This charge curve of a Lithium-ion cell plots various parameters such as voltage, charging time, charging current and charged capacity. When the cells are assembled as a battery pack for an application, they must be charged using a constant current and constant voltage (CC-CV) method.

Li-Ion batteries are readily damaged by charging at too high a voltage. Internal gassing, overheating, and finally exploding might occur if the charging voltage is pushed over its optimal value of 4.1 V or 4.2 V. Even a 1% rise in voltage over this ideal level could induce the lithium ions in the cell to start converting to metallic lithium.

The capacity of a battery is generally rated and labeled at 3C rate(3C current), this means a fully charged battery with a capacity of 100Ah should be able to provide 3*100Amps current for one third hours, That same 100Ah battery being discharged at a C-rate of 1C will provide 100Amps for one hours, and if discharged at 0.5C rate it provide 50Amps for 2 hours.
