AI Customer ServiceThe charging and discharging of lithium ion battery is actually the reciprocating motion process of lithium ions and electrons. When charging, apply power to the battery to let lithium ions and electrons go to the graphite layer along different paths. At this time, lithium atoms It is very unstable.
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.
During discharge, lithium ions move from the anode back to the cathode. This movement generates an electric current, which powers your device. Proper discharge management is essential to avoid over-discharging, which can permanently harm the cell and diminish its capacity. 2. Li-Ion Cell Discharge Current
Lithium-ion cells must not be discharged below their minimum recommended voltage as it can cause irreversible damage to them. Now that the details of the standard charging and discharging protocols have been reviewed, let’s look at how charging and discharging is applied in life cycle testing and in formation.
The charging and discharging of lithium ion battery is actually the reciprocating movement of lithium ions and free electrons. Different metals have different electrochemical potentials. Electrochemical potential is the tendency of metals to lose electrons. The electrochemical potentials of some common metals are shown in the figure below.
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.
