This means that during the charging and discharging process, the lithium ions move back and forth between the two electrodes of the battery, which is why the working principle of a lithium-ion battery is called the rocking chair principle. A battery typically consists of two electrodes, namely, anode and cathode.
When a lithium-ion battery is in use, the stored energy is released as the lithium ions move back from the anode to the cathode through the electrolyte. This movement of ions creates a flow of electrons, which can be used to power various devices. What makes lithium-ion batteries popular in electronic devices?
During charging, lithium ions move from the cathode to the anode through an electrolyte, which is a conductive solution. This process allows the battery to store energy.
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.
CV (Constant Voltage Charging) The constant voltage (CV) threshold for lithium batteries is typically 4.1v to 4.5v per cell. The charging IC monitors the battery voltage during constant current charging. Once the battery reaches the constant voltage charging threshold, the charger IC transitions from constant-current to constant-voltage regulation.
