A lithium-ion battery’s charging cycle works through a process known as electrochemical reactions. During the charging cycle, these reactions occur within the battery’s cells to store electrical energy. What happens during the charging process of a lithium-ion battery?
The charging cycle of a lithium-ion battery involves several distinct stages. During the charging process, a current is applied to the battery, causing positively charged lithium ions to move from the cathode to the anode through an electrolyte. This influx of lithium ions increases the energy storage capacity of the battery.
A lithium-ion battery, also known as the Li-ion battery, is a type of secondary (rechargeable) battery composed of cells in which lithium ions move from the anode through an electrolyte to the cathode during discharge and back when charging.
When the battery is charging, positively-charged lithium ions move from one electrode, called the cathode, to the other, known as the anode, through an electrolyte solution in the battery cell. That causes electrons to concentrate on the anode, at the negative side. When the battery is discharged, the reverse happens.
When your battery is discharging, Battery University recommends that you only let it reach 50 percent before topping it up again. While you’re charging it back up, you should also avoid pushing a lithium-ion battery all the way to 100 percent. If you do fill your battery all the way up, don’t leave the device plugged in.
Now that you have your preferred gadget take a seat, and let’s explore the world of lithium-ion battery charging. Rechargeable power sources like lithium-ion batteries are quite popular because of their lightweight and high energy density. Lithium ions in these batteries travel back and forth between two electrodes when charged and discharged.
