The performance of lithium-ion batteries decays year by year, but this is loved by smartphone manufacturers. This is because consumers tend to buy a new device every two years when they can't stand the shortage of battery life. If you don't want to fall into this trap too quickly, then you may want to refer to a team of researchers at the University of Michigan, Ann Arbor, summed up the many maintenance methods to "extend the life of the battery".
The team reportedly analyzed dozens of academic papers and manufacturer's manuals to compile a series of best practices for extending the life of lithium-ion batteries as long as possible.
With the passage of time, all components on a cell phone will experience some degree of decline, and the battery's poles, electrolyte, diaphragm, and collector fluid are no exception.
The first piece of advice from the University of Michigan, Ann Arbor research team is this -- avoid exposure to temperatures that are too high or too low, especially during the charging process.
If your phone overheats while charging, remember to disconnect the charger promptly, and in addition avoid charging in extremely cold conditions. This is because extreme temperatures may accelerate the degradation of almost all battery components.
With this in mind, some electric vehicle manufacturers even recommend that owners turn on the power when the weather is hot so that the on-board cooling system can operate smoothly. However, if the temperature exceeds 10-35°C (50-95°F), charging should be avoided.
Second, the battery should not be overcharged or depleted to too low a level. Ideally, keep it at just over 80% charge and above 20% remaining charge.
The reason for this is that when the battery is over 80% charged, the battery should be fully charged.
The reason is that when the charge is over 80% or below 20%, it will put a lot of stress on the Li-ion battery and cause its performance to deteriorate.
If you really need 100% charge, please remove the charger when it is fully charged to avoid working on the battery overnight, and be careful not to let the battery lose charge for too long.
Third, if possible, please avoid rapid charging and discharging. Although fast charging is very convenient, high current brings higher heat generation and greater risk of degradation to the battery.
The same is true for the hazards of high discharge rates, power-hungry applications, and slamming on the electric door are also quite detrimental to the battery.
To avoid abnormally shortened battery life, try to use low-powered slow charging when conditions allow, unless you're really in a hurry.
Finally, the research team recommends not using or storing lithium-ion batteries in wet environments and avoiding mechanical damage such as punctures.
In summary, users need to be careful to observe the ambient temperature, charge and discharge slowly, do not leave the charger for long periods of time, and maintain a 20-80% charge when not necessary.
If consumers can replace batteries less often, it also has a greater significance for environmental protection.
