The battery is important is these three steps:
Step 1: Judgment voltage
Step 2: Judgment 3V
Step 3: Judgment voltage> 4.2V, constant voltage charging, voltage is 4.20V, and the current is reduced with the voltage until it is full.
1, briefly, lithium battery and working principle
Since 1990, the lithium-ion battery has been developed rapidly due to its excellent performance and is widely used in society. Lithium-ion batteries quickly occupy many fields, like mobile phones, laptops, small cameras, and so on.
At present, the basic principles of lithium batteries are the so-called “rock chair theory”. The charge of the lithium battery does not achieve electron transfer through the conventional manner, but through the transportation of lithium ions in the crystal of the layer of substance, energy changes. In the normal stamping case, the transportation of lithium ions generally only causes changes in the layer spacing without causing damage to the crystal structure, and therefore, the lithium ion battery is an ideal reversible battery from the reflection of the transistor. When the charge is charged, the lithium ion is positive and returned to and from the battery. It is like a rocking chair to sway in the positive negative pole, so some people refer to the lithium-ion battery image as a rocker chair.
The superiority of the lithium-ion batteries we often say is for traditional nickel-cadmium batteries (Ni / CD) and nickel-hydrogen batteries (Ni / MH). It has the advantages of low non-memory effects of high-capacity long-range self-discharge ratio of operating voltage.

2, common sense during daily use of lithium batteries
(1), misunderstanding: “Battery activation, the first three charge for more than 12 hours”
For the “activation” problem of lithium batteries, many statements are: charging time must be more than 12 hours, repeated three times to activate the battery. This “first three-three charging 12 hours more” said that it is obvious to continuing from nickel batteries such as nickel-cadmium and nickel hydrogen. So this kind of saying, it can be said that it is misfinalized. After sampling investigation, it can be seen that there is a considerable number of people confused the charging method of the two batteries.
The charge and discharge characteristics of lithium batteries and nickel batteries have a very different, all serious formal technical information you have reviewed emphasize that overcharge and over-discharge will cause huge damage to lithium batteries, especially liquid lithium-ion batteries. Therefore, charging is charged according to standard time and standard method, especially for ultra-long charging more than 12 hours. Generally, the charging method described in the mobile phone manual is the standard charging method suitable for the mobile phone.
Lithium battery’s mobile phone or charger will automatically stop after the battery is full, and there is no “trickle” charging for nickel electric chargers for 10 hours. If the lithium battery is filled, it is no longer charged on the charger.
Emperient time charging and complete empty power can cause excessive charging and excessive discharge, which will cause permanent damage to the lithium ion battery, from the molecular level, excessive discharge will cause the negative electrode carbon to excessively release lithium ion to make the sheet The layer structure has collapsed, and excessive charging will take too much lithium ion hard to the negative electrode carbon structure, but some of the lithium ions can never be released.
