Typically, you charge lithium batteries by applying the CC-CV scheme. CC-CV stands for Constant Current - Constant Voltage. It denotes a charging curve where the maximum allowed charging current is applied to the battery as long as the cell voltage is below its maximum value, for example, 4.2 Volts.

The recommended charging rate of an Li-Ion Cell is between 0.5C and 1C; the full charge period is approximately TWO TO THREE hours. In "1C", "C" refers to the AH or the mAH value of the battery, meaning if the Li-ion cell is rated at 2600mAH then the "C" value becomes 2600, or 2.6 Amps, which implies that it can be charged at its full 1C, or at 2.6 amps

How to Charge Lithium-ion (or LiFePO4) Batteries? There are several ways to charge Lithium batteries – using solar panels, a DC to DC charger connected to your vehicle''s starting battery (alternator), with an inverter charger, or with a portable 12V battery charger or 24V battery charger. While charging LiFePO4 batteries with solar is perfect for sunny days, you
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.
How long does it take to charge a lithium battery. The time it takes to charge a lithium battery depends on several factors, including the power output of the charger and the capacity of the battery. Generally, charging a lithium battery can take anywhere between 1-4 hours, depending on the specific charger and battery combination.

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.
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)
Lithium-ion (Li-ion) cells degrade after repeated cycling and the cell capacity fades while its resistance increases. Degradation of Li-ion cells is caused by a variety of physical and chemical mechanisms and it is strongly influenced by factors including the electrode materials used, the working conditions and the battery temperature.
