Here is a general overview of how the voltage and current change during the charging process of lithium-ion batteries: Voltage Rise and Current Decrease: When you start charging a lithium-ion battery, the voltage initially rises slowly, and the charging current gradually decreases. This initial phase is characterized by a gentle voltage increase.
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.

For example, a fully charged lithium-ion battery might have a voltage of 4.2V, while it may drop to around 3.0V when discharged. Why is voltage important?
Steady Voltage and Declining Current: As the battery charges, it reaches a point where its voltage levels off at approximately 4.2V (for many lithium-ion batteries). At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease.
