What are the ways to distinguish the pros and cons of lithium batteries?

How to identify a lithium battery? A lithium battery is a battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Lithium batteries can be divided into two categories: lithium metal batteries and lithium batteries. Today, the technical staff will share with you: How to identify lithium batteries? 1. Look at the plastic appearance and plastic material: the genuine battery has a uniform anti-wear surface, using PC material, without brittle cracks; the fake battery has no anti-wear or too rough surface, so choose Recycled raw materials are easy to be brittle and crack. Measure the charging voltage of the battery block. If nickel-cadmium batteries and nickel-metal hydride batteries are used as lithium-ion mobile phone batteries, they must be packaged with 5 single cells. The charging voltage of a single battery does not exceed 1.55v, and the total voltage of the battery block does not exceed 7.75v. When the total charging voltage of a battery is lower than 8.0v, it is likely to be a nickel-cadmium battery and a nickel-hydrogen battery. 2. Original battery: The appearance of the battery is clear, uniform and clean, without obvious scratches and damage; the battery model, variety, rated capacity, standard voltage, positive and negative signs and manufacturer's name should be printed on the battery logo. The handle is lubricated without clogging, suitable for air-tightness, best fit with the hand, and reliable locking; no obvious scratches, blackening, or greening. If the mobile phone battery we buy does not meet the above phenomenon, it will start to conclude that it is a fake. 3. Compare battery capacity: Generally nickel-cadmium battery is 500mAh or 600mAh, nickel hydroxide battery is 800-900mah; and the capacity of lithium-ion mobile phone battery is generally between 1300~1400mAh, so the use torque of lithium battery is about nickel-hydrogen battery 1.5 times that of nickel-cadmium batteries, which is about 3.0 times that of nickel-cadmium batteries. If it is found in the book that the lithium-ion cell phone battery block you have purchased has not been announced or stated the specified length, it is likely to be an imposter. 4. Many mobile phone manufacturers also proceed from their own point of view: by working hard to improve the level of technology, increasing the difficulty of counterfeiting mobile phones and accessories, and further curb the phenomenon of the proliferation of counterfeit gray goods. General mobile phone products and accessories must have the same appearance under general requirements. So if we buy a mobile phone battery installation, should we carefully check the body and the bottom shell of the battery? The color, if the color is the same light and dark, is the original battery. Otherwise, the gloss of the battery itself will be dim and it may be a fake battery. 5. Observe the abnormal charging situation: Generally speaking, there should be an over-current maintainer inside the real mobile phone battery. If the current is too large due to an external short circuit, you should actively cut off the circuit to avoid burning or damaging the phone; lithium batteries also have an over-current retention system. When using non-standard electrical appliances, excessive current will also actively cut off the power supply, resulting in loss of charge. In the normal state of the battery, the state can be restored actively. If, during the charging process, we find that the battery is seriously heating or smoking, or even exploding, it means that the battery must be fake.
