26650 lithium battery

　　There are two basic methods for naming lithium batteries. One is from the cathode material of lithium batteries, and the other is from the size. These two basic classifications start from the common aspects and have general characteristics. In addition, there are classifications from certain performance or application, which start with personality and have specific characteristics. The 26650 lithium battery is classified from the dimension, so it has a common shape. Its cathode materials, performance and application fields are diversified.

　　26650, the strict definition means that the size of the single electric core is 26mm in diameter and 65mm in height. The size of this cylinder appearance varies slightly from manufacturer to manufacturer in actual production. The so-called "height, height, fat and thin are all different", which is called 26650. However, this difference will not be large, neither will the diameter exceed 27mm, nor will the height exceed 66mm. When a single battery cell is put into use with the support system, it is a 26650 lithium battery. If multiple lithium cells or lithium batteries are combined, it is called a lithium battery pack. To be more precise, it is a 26650 lithium battery pack.

　　Like the 18650 lithium battery, the 26650 lithium battery can also use different cathode materials. According to the current market application, there are basically 26650 ternary lithium battery and 26650 lithium iron phosphate battery. The difference between the two is also the general difference between ternary lithium battery and lithium iron phosphate battery. The former has the advantages of high capacity and voltage platform, while the latter has the advantages of safety and high starting current. Combined with the actual situation that most 26650 lithium batteries are used for equipment startup, 26650 lithium iron phosphate batteries are mainly used, and these batteries have obvious advantages in safety and price.

　　Many factories will produce 26650 lithium iron phosphate batteries. Although they are different in personality, their basic parameters should conform to international standards. Here we choose the relevant parameters of Dongguan Juda Electronics Co., Ltd., a customized lithium battery manufacturer, to give you a visual and general understanding of the 26650 lithium battery. The overall dimensions of the company's 26650 lithium battery: 26.4 * 65.8mm at maximum, 3000mAh at nominal capacity, 3.2V at nominal voltage, 3.65V and 2.5V at cut-off voltage, 1500mAh at standard charge discharge current, 1C charge and 1.5C discharge at maximum, operating temperature of - 10 ℃~+60 ℃.

　　The 26650 lithium iron phosphate battery has stable charging and discharging performance, high temperature resistance, and a cycle life of three times that of ternary materials. Because it can be charged and discharged with high current, it is extremely suitable for bright flashlights, miner's lamps, instruments and meters, etc. Moreover, this advantage enables it to develop towards large-scale development. For example, Dongguan's huge 26650 power lithium iron phosphate battery technology has matured.
