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.
This research provides a reliable method for the analysis and evaluation of the charging and discharging characteristics of lithium batteries, which is of great value for improving the safety and efficiency of lithium battery applications.
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.
They operate based on the principles of charging and discharging, which involve the movement of lithium ions between the battery’s electrodes. During the charging process, an external power source is connected to the battery, and a voltage higher than the battery’s current state of charge (SoC) is applied.
Taking the charging process of lithium battery as an example, the current and voltage of lithium battery will change with the time of charging, which belongs to a working process of constant current and constant voltage before . The charging principle of lithium battery is shown in Fig. 1. Working process diagram of lithium battery charging
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. And discharging is to apply a load to the battery, allowing lithium ions and electrons to run to the side of the metal oxide along the previous path.
