Many friends do not know how to charge and discharge a new lithium battery after buying a new one. What are the precautions for the first charging of a lithium battery? The following will tell you the correct way, let's take a look.
The lithium battery that we often mention in our daily life, also known as lithium-ion battery, is a battery developed by using the active chemical characteristics of lithium metal. The essence of the charging and discharging process of the battery is actually achieved through the gains and losses of electrons, which is a process of redox reaction. Therefore, it does not have a memory effect like a nickel-hydrogen battery during use, and there is no need to worry about the battery capacity being reduced due to not being fully charged. Of course, due to the active nature of lithium metal, it is easily affected by the environment. In the process of using lithium batteries, we need to pay attention to some problems.
When we use lithium batteries, it should be noted that after the battery is left for a period of time, it will enter the dormant state. At this time, the capacity is lower than the normal value, and battery life is also shortened. But the lithium battery is easy to activate, 3-5 normal charge and discharge cycles can activate the battery and restore normal capacity. Due to the characteristics of the lithium battery itself, it is determined that it has almost no memory effect.
Therefore, the new lithium battery in the user's mobile phone does not require special methods and equipment during the activation process. Not only is it true in theory, but from my own practice, it is best to use the standard method of charging from the beginning, which is the "natural activation" method.
After the lithium battery has been activated and left the factory, it still needs to be activated a second time. It is recommended to perform a full charge and discharge process 3-5 times when you use the battery for the first time, which is very beneficial to the battery life. Lithium batteries are very susceptible to environmental temperature. The charging temperature should be kept at 25-40 degrees Celsius as much as possible. Charging at low or high temperatures will cause damage to the battery.
The safe working voltage range of lithium batteries is 2.8~4.2V. Lower or higher temperatures beyond the range will make the lithium ions in the battery become very unstable, and will even cause accidents. In order to ensure that the battery is in a safe range, a special charger is required. These chargers automatically adjust the charging method according to the current state of the battery.
Generally, there are individual requirements for chargers of various lithium battery manufacturers, so do not change the charger at will when you are not sure.
No special method is required when the new lithium battery of the mobile phone is charged for the first time. It can be determined according to the actual power situation. If the power is lower than 20%, it is recommended to charge it before using it. If the power is higher than 20%, you can charge or wait to charge when the battery level drops to 20%. Unplug the charger when the battery is full.
Lithium-ion batteries do not have the memory effect of nickel-cadmium batteries, and they are activated before leaving the factory, so they can be recharged anytime and stand by in daily use. But in order to fully extend the battery life, you need to pay attention to the following issues when charging:
● Try to ensure that the mobile device is running the latest version of the system for the new system usually contains more advanced energy-saving technology.
● Avoid charging in places where the temperature is higher than 35°C, otherwise, the capacity of the lithium battery may be permanently damaged. Storing the battery in a high-temperature environment may also cause irreparable damage.
● It is best to remove the protective shell of the mobile phone when charging it, so as to prevent the mobile phone from generating more heat due to the blocking of the protective shell during the charging process.
● When the mobile phone is not used for a long time, do not charge it or discharge it completely, keep the power at about 50%, turn off the power switch and store it in a cool and dry place.
Lithium battery is a kind of consumable product, and its life span is fixed, so mastering the correct method of using lithium battery is the secret to extend the battery life.
The above shows the correct way to charge the lithium battery for the first time, and the tutorial about the correct use of the lithium battery. If you don't know how to use the lithium battery, please try the method in the tutorial as soon as possible. I hope it will be helpful to everyone.
