The most detailed charging method of mobile phone polymer lithium battery

　　Lithium batteries are widely used, so the charging mode of lithium batteries has attracted much attention. For different lithium batteries, there are usually different charging methods for lithium batteries, which is why we cannot fully master the charging methods for lithium batteries in a short time. In order to help you correctly understand the charging method of lithium battery, this article brings a correct introduction to the charging method of mobile phone lithium battery. Let's understand it together. At present, the mobile phone battery in China has completed the transition from nickel metal hydride nickel cadmium battery to lithium battery, but most people still use the old fault method of nickel metal hydride nickel cadmium battery. This article specifically explains the correct use of lithium battery, which is the most widely used battery. It also checks the number of misunderstood people by sampling, and explains the correct method of charging lithium battery for the first three times. Since its appearance in 1990, lithium-ion battery has been developed rapidly with its excellent performance, and has been widely used in the civil field. Lithium ion batteries have many advantages over other batteries, such as mobile phones, laptops, small cameras, etc. Lithium ion battery is an aspiring small green power supply. We often say that the advantages of lithium ion batteries are related to traditional nickel cadmium batteries (NiCD) and nickel hydrogen batteries (NiMH). It has the advantages of high working voltage, large specific energy, long cycle life, low self discharge rate and no recall effect. It is now recognized that the basic principle of lithium battery is the so-called "rocking chair theory". The charge and discharge of lithium battery cannot complete the electron transfer through traditional methods. In childhood, energy changes occur through the ingress and egress of lithium ions in strong matter crystals. Under normal charging and discharging conditions, the lithium ion ingress and egress generally only cause the change of layer spacing, but will not cause damage to the crystal structure. Therefore, from the perspective of pulse discharge reflection, lithium ion battery is an ambitious reversible battery. During charging and discharging, lithium ions move back and forth between the positive and negative poles of the battery, just like a rocking chair, swinging between the positive and negative poles. Therefore, the image of lithium-ion battery is called rocking chair battery.
