List of charging misconceptions and correct charging methods of
lithium battery manufacturers for mobile energy storage
Nowadays, mobile phones have become an essential communication tool for us. However, in order to make your phone last longer and safer, you must know the correct charging method for your phone, as well as the misconceptions about charging your phone battery
Mobile phones are essential items for modern people. Nowadays, almost everyone has a mobile phone, and charging it has become a daily necessity for us. But do you know what are the misconceptions about charging mobile phone batteries? What is the correct charging method for mobile phones? Let's take a closer look below.
Misconception 1 of mobile phone charging: How many times do new batteries need to be fully charged and discharged to activate
Lu Jianguo, Director of the Comprehensive Inspection Department of the National Household Appliance Quality Supervision and Inspection Center of the China Academy of Home Appliances, told reporters that different battery products require different methods of charging, and must be used according to the product instructions. Early nickel cadmium batteries and nickel hydrogen batteries required similar "activation". These batteries produce a 'memory effect', charging them in an incompletely discharged state can easily lead to overcharging, and over time, users may feel like their battery is running out quickly. However, most of the batteries used in mobile phones and laptops today are lithium-ion batteries. Its initialization process has been completed during manufacturing, so it does not need to be activated when it is first used.
Misconception 2 of Mobile Phone Charging: Reducing Charging Times Can Extend Battery Life
The lifespan of a typical lithium-ion battery can reach several hundred charge and discharge cycles, where the charge and discharge cycle refers to the process of using up the battery before recharging, rather than simply plugging in the charger and unplugging it once. Energy storage lithium battery manufacturers do not have a memory effect and can be charged at any time. Deliberately using up the battery before recharging it in order to reduce the number of charging times does not prolong the battery life, but has a negative impact on the battery life. In addition, if the mobile phone uses automatic shutdown, the energy storage lithium battery manufacturer may experience low internal voltage due to excessive discharge, which may result in the inability to turn on and charge. Therefore, manufacturers of energy storage lithium batteries pay attention to "eating less and having more meals" when charging, and frequent shallow charging and discharging are more helpful in extending their lifespan.
Misconception 3 of mobile phone charging: Overcharging can cause battery explosion
Energy storage lithium battery manufacturers generally have safety protection circuits and various safety devices to ensure that the battery circuit is automatically cut off in the event of overcharging, discharging, or short circuits; Excessive internal pressure in the battery can also trigger the exhaust system to reduce pressure; If the battery temperature is too high, it will trigger the hot melt protection device, thereby stopping the electrochemical reaction of the battery. Therefore, unless there is a quality issue, the battery will not explode due to prolonged charging. However, not unplugging the power after being fully charged will keep the battery fully charged. Although it will not explode, it will accelerate the rate of battery capacity loss.
Additionally, there are rumors that answering a phone while charging can cause an explosion. Experts say that this statement is untenable. If such a danger really exists, the product will set a program to not connect to the phone during charging. However, from a health perspective, wires can limit the user's range of motion, and making or receiving phone calls while charging may keep the user fixed in one place for a long time, causing excessive muscle tension. Therefore, it is recommended to unplug the power before making calls. When charging, do not cover anything on the battery and do not place it on the bed to avoid a fire.
