What types of 18650 lithium batteries are there?

The first type of lithium battery is divided into square lithium batteries according to their appearance, such as cell phone batteries and cylindrical lithium batteries that are commonly used. For cylindrical lithium batteries, the model is generally 5 digits. The first two digits are the diameter of the battery, and the middle two digits are the height of the battery. The unit is millimeters, just like 18560 lithium batteries. The second type is divided into aluminum shell lithium batteries, steel shell lithium batteries, and soft pack batteries according to the lithium battery outsourcing materials. The outsourcing material of lithium batteries is the material that covers the surface of the lithium battery. The same material classification is not the same. There are more aluminum-case lithium batteries and steel-case lithium batteries on the market. The third type of 18650 lithium battery is based on the positive and negative electrode materials of lithium batteries. Lithium acid batteries or lithium manganese batteries, as well as lithium iron phosphate batteries, and disposable lithium manganese dioxide batteries; lithium iron phosphate is more common among these types Yes, lithium iron phosphate battery is also called lithium iron phosphate power lithium ion battery, because its performance is very suitable for power related aspects. Lithium cobalt oxide battery has a stable structure, high capacity ratio, outstanding comprehensive performance, but its shortcomings are poor in safety and high in cost, so it must be used in small and medium-sized batteries and used in small electronic devices such as notebook computers, mobile phones, and MP3/4. The fourth type is divided into power-type batteries and energy-type batteries according to battery practicality. Energy batteries are characterized by high energy density and are mainly used for high energy output; power batteries are characterized by high power density and are mainly used for batteries with instantaneous high power input and output. Just like running, the energy type is a 1000-meter long run and the power type is a 50-meter sprint. The 1000-meter long-distance running requires endurance and a large capacity. The requirements for high-current discharge performance are generally not high or even low. The 50-meter sprint fights for explosive power, but endurance is also necessary, otherwise the capacity is too small and it will not run far.
