The lifespan of lithium battery is affected by many factors, generally speaking, the life of lithium battery under normal use can reach several years or more than ten years.
Different from other disposable batteries, lithium batteries can be charged and discharged cyclically. What helps to realize the cycle of charging and discharging is the free movement of lithium ions in lithium batteries. With charging and discharging, lithium ions keep moving between the positive and negative electrodes, resulting in the constant movement of electrons between the positive and negative electrodes. At the same time, lithium batteries in rechargeable batteries, belong to the low price and good charging and discharging effect, so many industries as the preferred application.
As lithium batteries each charge and discharge, physical and chemical changes will occur within the battery, these changes will damage the battery itself, resulting in a decrease in the total amount of power that can be held by the battery, and thus reduce the service life of the battery, which is a normal phenomenon. Because of this phenomenon, devices that use lithium batteries, such as smartphones, electric cars and solar energy systems, have a fixed number of charges. However, if more than this number of lithium batteries will not immediately stop working, but the battery capacity will be reduced.
Lithium batteries are installed in different environments, not only can affect the service life of lithium batteries, but also affect their efficiency. For example, high temperature will affect the service life of the battery, and low temperature will make the battery performance decline in use, and extreme temperatures can even lead to battery damage.
Secondly, the service life of lithium battery will also receive the impact of humidity. It is not suitable for environments with high humidity, because the performance and life of lithium batteries will be affected when they are damp.
It is worth noting that placing it in the sun will also affect the life of the lithium battery. In many installations where lithium batteries are applied, they are exposed to the outdoors. Then when it is too hot outside, the sun’s exposure will also affect its life, so pay attention to the shade when using lithium batteries outdoors.
Lithium battery charging will generally have the original adapted charger. If you use other lithium batteries with different power chargers may also reduce the life of lithium batteries. Excessive charging power will lead to damage and shorten the life of the lithium battery, while the small power charger needs a lot of time to fully charge the lithium battery.
For rechargeable batteries, overcharging or frequent charging, the chemical reaction inside the battery will be very violent, this process will also greatly increase the number of battery charging and discharging cycles, very damaging to the battery. In the long run, the performance and service life of the battery will be greatly reduced. At the same time overcharging caused by the internal chemical reaction of the battery will lead to a lot of heat accumulation inside the battery, which will make the lithium battery capacity decline, and even the risk of fire.
Over-discharge will lead to increased pressure inside the battery, destroying the internal structure, resulting in a significant decline in battery capacity, which may be difficult to restore to the original level even through charging, thus reducing the battery life.
Battery in the temperature and humidity is appropriate, at the same time there is good ventilation, avoid sun exposure to the environment, the battery by the environmental factors to reduce the impact of the battery chemical properties of the decline in the speed of slowing down, the battery naturally have a longer service life.
Battery life is constrained by cycling factors, overcharging and frequent charging will greatly increase the number of cycles of the battery, and complete discharge will make the battery withstand much greater than the full state of pressure, which in turn affects the battery energy density.
To avoid overcharging and overdischarging, we can equip a charge controller on both the charging and discharging circuits, always calculating the voltage of the lithium battery, so as to avoid overcharging and overdischarging and increase the life of lithium batteries.
Normally the labelling date is provided by the business as a guide to the purchase of the basis of the older lithium batteries produced farther away from the date of the life of the battery tends to be shorter. However, we need to understand that these labelling date is not absolute. Under normal circumstances, we need to buy under the guidance of professionals!
Adaptive chargers not only ensure that the battery is charged at a suitable charging power to reduce heat build-up, but also most adaptive chargers can automatically turn off the charging after a full charge to protect the battery, while achieving the purpose of improving battery life.
