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.
The 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.
Constant current discharge is the discharge of the same discharge current, but the battery voltage continues to drop, so the power continues to drop. Figure 5 is the voltage and current curve of the constant current discharge of lithium-ion batteries.
When charging and discharging lithium-ion batteries, the current is an important factor to consider. The current flowing into the battery during the charging process determines how quickly the battery charges. A higher current means a faster charge time, while a lower current means a slower charge time.
When using and charging a lithium-ion battery, it’s critical to keep the current in mind because it can affect the battery’s performance and lifespan. Understanding the relationship between current and charging and discharging in lithium-ion batteries can help ensure that the battery is used and maintained correctly.
Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current. This point is commonly referred to as the “charging cut-off current.” II. Key Parameters in Lithium-ion Battery Charging
