Lithium batteries consist of three main components: a positive cathode, a negative anode, and an electrolyte that facilitates the flow of ions between the two electrodes.
How Lithium Batteries Work
When a lithium battery is charged, lithium ions are extracted from the cathode and inserted into the anode through the electrolyte. This process is known as intercalation, and it allows the battery to store energy in the form of chemical bonds. When the battery is discharged, the process is reversed, and the lithium ions flow back to the cathode, releasing energy in the form of electricity. This process can be repeated hundreds of times, making lithium batteries a reliable and efficient source of power.
Charging Requirements for Lithium Batteries
Lithium batteries require a specific charging protocol to ensure safe and efficient charging. The charging process typically involves three stages: constant current, constant voltage, and trickle charging.
