6 FAQs about [Charging and discharging current of lithium battery]

What is lithium ion battery charging & discharging?

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.

How Lithium ion battery is charged and discharged?

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.

What is the charging voltage of a lithium battery?

The charging voltage of lithium batteries is usually 4.2V and 4.35V, and the voltage value will be different if the cathode and anode materials are different. The battery voltage is one of the important indicators to measure the discharge performance.

How does a lithium battery charging curve affect the charging speed?

During the charging process of a lithium battery, the voltage gradually increases, and the current gradually decreases. The slope of the lithium battery charging curve reflects the fast charging speed. , the greater the slope, the faster the charging speed.

How do you charge a lithium ion battery?

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.
