However, like all batteries, lithium-ion batteries have limitations and can degrade over time, affecting their overall performance and lifespan.
How Lithium-Ion Batteries Work
Lithium-ion batteries operate by transferring lithium ions between two electrodes, the anode and the cathode, through an electrolyte. This process allows the battery to charge and discharge. The battery’s capacity to hold a charge is measured in milliampere-hours (mAh), and its voltage is typically around 3.7 volts for a standard lithium-ion battery used in smartphones.
Battery Cycle Life and Depth of Discharge
The cycle life of a battery refers to the number of charge and discharge cycles it can handle before its capacity starts to degrade significantly. A full cycle is considered a discharge from 100% to 0% and then back to 100% charge. The depth of discharge (DOD) is the percentage of the battery’s capacity that is used before it is recharged. For example, if a battery is discharged from 100% to 50% and then recharged to 100%, that counts as half a cycle.
