What are the misunderstandings about 18650 lithium batteries?

Misunderstanding 1: 18650 has fallen behind. It has been 30 years since the birth of the low-end product 18650 lithium battery. Not only did it not stop processing, but it also developed to be used globally. In fact, 18650 is used in a wide range, but we generally rarely see it straight. In our daily life, most of the laptop batteries we commonly use are battery packs composed of 18650 lithium batteries in series, but they are invisible to us because they are wrapped by the laptop battery shell. So is the 18650 lithium battery abandoned in notebooks today? Obviously not, only Apple notebooks and some brands of ultrabook computers that use polymer batteries. It is believed that the 18650 lithium battery will continue to be used in the notebook field for a long time. Misunderstanding 2: 18650 is not safe and easy to explode. The 18650 that we often talk about every day actually refers to the shape of the battery. It is a standard battery model set by the Japanese SONY company in order to save costs. Among them, 18 means 18mm in diameter and 65 means The length is 65mm, and 0 represents a cylindrical battery. 18650 lithium battery originally refers to nickel-metal hydride batteries and lithium batteries. Since nickel-metal hydride is relatively seldom used at present, it is more often referred to as lithium batteries. The nominal voltage of a single cell of 18650 lithium battery is generally: 3.6V or 3.7V; the minimum discharge termination voltage is generally: 2.75V. The common capacity is 1200～3100mAh, higher than 3400mAh is basically a virtual standard. Some mobile power manufacturers often promote the dangers and obsolescence of 18650 batteries when they promote their products, so as to emphasize the safety and superiority of their polymer batteries. Consumers who lack professional knowledge can easily be misled. In fact, whether it is an 18650 battery cell or a polymer battery cell, it only requires products with qualified quality, and its safety performance is the same and guaranteed. When consumers buy mobile power, it is more important to choose products with guaranteed quality. Feel free to listen to the propaganda of the manufacturer.
