What are the advantages and disadvantages of 18650 lithium battery and 26650 lithium battery?

Comparison of the advantages and disadvantages of 18650 lithium battery and 26650 lithium battery. The so-called 18650 lithium battery and 26650 lithium battery represent the size of lithium batteries. For example, 18650 lithium battery, 18 is the diameter of the battery, 650 is the height of the battery, and the unit of length is millimeters. The 26650 lithium battery refers to a cylindrical battery with a diameter of 26mm and a length of 65mm. What are the advantages and disadvantages of 18650 lithium battery and 26650 lithium battery? The advantages of 18650 lithium battery: large capacity, long life, high safety performance, no explosion, no burning; non-toxic, non-polluting, high voltage, no memory effect, charging There is no need to empty the remaining power before, it is easy to use, small internal resistance, can be combined in series or parallel to form a 18650 lithium battery pack, and has a wide range of use. Advantages of 26650 lithium battery: high energy density, low self-discharge rate, stable charge and discharge performance, no memory effect, no decomposition when exposed to heat, high safety performance, and long life cycle. , High voltage, can be used in series or parallel to form a 26650 lithium battery pack, environmentally friendly and pollution-free. 18650 lithium battery and 26650 lithium battery development status and historical reasons 18650 lithium battery is a standard lithium battery model successfully developed by SONY in 1992. It was born under the material level and manufacturing level at that time. It is a combination of battery cost and performance balance. appeared. In products such as notebooks, cameras, toys, and lighting equipment, 18650 batteries have been very mature and stable after years of development; at the same time, because of their long history, they have formed relatively mature market applications. With the development of new energy applications, the status of 18650 lithium batteries has gradually been impacted. Larger cylindrical lithium battery products and square battery products have appeared on the market in large numbers, such as 26650 lithium batteries with relatively good stability and consistency. , 21700 lithium batteries and square batteries with various specifications.
