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.
During charging, lithium-ion batteries exhibit distinct voltage characteristics that reflect their electrochemical processes. The charging cycle typically follows a constant current-constant voltage (CC-CV) protocol. Initially, the battery voltage rises steadily as current flows into the cell.
This initial phase is characterized by a gentle voltage increase. 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.
The most important key parameter you should know in lithium-ion batteries is the nominal voltage. The standard operating voltage of the lithium-ion battery system is called the nominal voltage. For lithium-ion batteries, the nominal voltage is approximately 3.7-volt per cell which is the average voltage during the discharge cycle.
I''ve noticed that the voltage after a load takes a few minutes to go back to the open voltage (voltage without load for a long time). Can anyone explain why it takes so long for the voltage

When we continue to utilize the battery, the voltage may drop to the nominal rate of 3.7V. When used more, the voltage could drop to 3.0V and will eventually reach the cell''s limits.
