The lifespan of a lithium battery is not calculated in years, but in cycles.
The lifespan of a lithium battery is “500 times”, which does not refer to the number of charges, but to one cycle of charging and discharging.
Nowadays, cell phones use lithium batteries. The number of cycles of most lithium batteries is generally about 500 times, that is, 0 to 100 corresponds to one cycle (a cycle of 100 corresponds to one cycle). reached 500 times, the mobile phone battery has already weakened, the internal resistance of the battery has increased, the activity of chemical elements inside has decreased, and it has entered a rapid consumption stage.
Everyone has had this experience. A very old cell phone turns off after making a call after being fully charged. It is understandable that the battery is exhausted.
Detailed information:
A charge cycle refers to the process in which all The battery's energy is used from full to empty, then charged from empty to full. This is not the same as a single charge. For example, a lithium battery only uses half its power the first day, then it is fully charged. If it is still the same the next day, i.e. if you charge it half and charge it twice in total, this can only be counted as one charging cycle and not two.
Therefore, multiple charges may typically be required to complete a cycle. Each time a charge cycle is completed, the battery capacity decreases a little. However, this power reduction is very small. High quality batteries retain 80% of their original capacity after multiple charge cycles. Many lithium-powered productsm-ion are still used as usual after two or three years.

How long does a lithium battery (cell phone battery) last?
The lifespan of lithium-ion batteries in ordinary electronic products is about 5 to 20 years, with an average of 8 years.
With the current technological level, the lifespan of lithium-ion batteries in electric vehicles is only about 3 to 5 years.
When the battery capacity of an electric vehicle drops below 80% of its initial capacity, the range of the electric vehicle will be significantly reduced.
When the battery capacity drops below 70%, the battery needs to be replaced. For many current pure electric vehicles, the battery cost represents around 40% of the total costof the vehicle. In other words, replacing the battery is like replacing half the car.
Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. Lithium metal batteries have been proposed and first studied by Gilbert N. Lewis in 1912. In the 1970s, MS WhitTingham proposed and began research on lithium-ion batteries. The chemical properties of lithium metal are very active, processing, storage and l. The use of lithium metal is subject to very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have now become common. p>
The lifespan of cell phone batteries, under standard conditionsales use and without serious impact, the lifespan set by the manufacturer must be 5 years. In wet and rainy areas, the battery. Lifespan Lifespan will be affected. Battery life is related to battery type and number of charges. For example, a nickel-metal hydride battery should be purchased after about 200-300 charges, a nickel-chrome battery can be charged 100-150 times. , and a lithium battery can be charged 350-300 times 700 times. The longer the interval between each charge and discharge of the battery, the longer the battery life. Battery life is therefore also related to how the battery is used.
