The correct use of lithium ion batteries and the charging time of lithium ion batteries

The correct way to use lithium-ion batteries 1. The lithium-ion batteries often mentioned in our daily lives, also known as lithium-ion batteries, are batteries developed using the active chemical characteristics of lithium metal. The essence of the charging and discharging process of the battery In fact, it is realized 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-ion batteries, we must pay attention to some problems. The correct use of lithium-ion batteries 2. Many people have a concept that the battery must be charged for a long time to activate the battery when it is first charged. When charging a lithium-ion battery for the first time, it is indeed necessary to add a proper charging time to fully charge it like the nickel-hydrogen battery. It is generally 8-12 hours, but not more than 12 hours, otherwise the battery may be reduced. life. But this process is not the process of activating lithium-ion batteries, because in the process of making lithium-ion batteries, manufacturers have already activated the lithium-ion batteries. The correct use of lithium-ion batteries 3. In terms of charging and discharging, after a lithium-ion battery is charged and discharged for 300 to 600 times, the battery life is basically exhausted, and the so-called cyclic charging and discharging process is completely exhausted. The process of discharging and fully charging. Therefore, general electronic products should be charged immediately when the battery is low, and the battery can be unplugged after charging less than 100. There is no need to shut down and charge, reducing a cycle of charging and discharging process is also reducing the consumption of battery life. The correct use of lithium-ion batteries Fourth, in addition, because the safety of lithium-ion batteries is relatively low and sensitive to the temperature in the environment, we should pay more attention to the temperature of the environment when using lithium-ion batteries. 40 degrees Celsius to 60 degrees Celsius is the best temperature for lithium-ion batteries, and according to research, the higher the temperature, the easier it is to reduce the battery's life. When the battery is exposed to an environment exceeding 60 degrees Celsius for a long time, it is likely to explode, causing life-threatening danger. Li-ion battery charging time. The charging speed of lithium-ion batteries is generally not fixed. It should be determined according to the capacity of the battery, the current of the charger, and the conversion efficiency of the charging; if your battery has a relatively high capacity If the current of your charger is small, the charging speed will be slower if the maximum input current is not reached; however, the approximate charging time can be estimated according to a relatively fixed formula: charging time (minutes) u003dBattery capacity*1.2/Current (mA)*60, where the factor of 1.2 multiplied by it is the loss that may occur during the charging process; in addition, it should be noted that the battery should not be activated during the new battery stage, as long as there is no battery in daily use. Normally charge when powering up. If you continue to use the battery until it is dead or low, it will have an impact on the life of the battery; Disclaimer: Some pictures and content of articles published on this site are from the Internet.
