Yes. Lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. Mobile phone batteries are lithium batteries, which are different from rechargeable batteries, lithium-ion batteries and lithium-ion polymer batteries. . For laptop batteries, mobile phone batteries, MP3\MP4\PSP lithium batteries: no matter it is a new battery, it can be unplugged and used when fully charged . Typically, it will be fully charged in 2-4 hours. Do not charge it for more than 8 hours to 12 hours, as this is harmful and unnecessary. When a cell phone low battery prompt appears, you should try to start charging as soon as possible. Activation of lithium batteries does not require special methods. , and the batterieshave been activated before leaving the factory. If you insist on using the popular "first three activations of 12 hour charge" method, it will actually not be effective.
The repair method for 18650 lithium battery that cannot be charged is as follows:
1 The reason why the 18650 battery cannot be charged. is that the battery electrodes are in contact with each other. The points are rusty or dirty, resulting in too much contact resistance and a large voltage drop, causing the charger to think it is fully charged and stop charging in this case; , you just need to shock the electrodes and clean them.
2. After eliminating the problem with the battery itself, check if there is a problem with the charger or charging cable. If there is other charging equipment, you can try to replace it,due to faults in the system. The charger and cable may also prevent the 18650 from charging.
3. If there is a problem with the internal circuit, the battery itself, or the battery life that is preventing the battery from charging, it is recommended to replace the battery directly. If you need to disassemble the 18650 battery, you must drain all the energy from the battery, but it is strongly not recommended to perform such an operation.
Principle of repair
1. Repair principle 1: The metal surface of lithium batteries used for a long time will be oxidized to a certain extent, resulting in poor contact between the mobile phone battery and the mobile phone, the service life of the lithium battery is shortened. The rust on the surface can be wiped off with an eraser or other cleaning tools, so that the battery and the mobile phone have better contact.
2.Repair Principle 2: Low temperature can change the electrolyte inside the lithium battery and promote the chemical reaction of the newly frozen battery. The process of using a lithium battery is actually a process of charging and discharging. During this time, the negative and positive charges of the battery collide.
