There are two basic methods for naming lithium batteries, one is based on the positive electrode material of the lithium battery, and the other is based on the size. These two basic classifications start from the common aspect and have general characteristics. In addition, there is a classification based on a certain performance or application, which starts from the perspective of personality and has specific characteristics. 26650 lithium batteries are classified based on size and therefore have a common appearance. Their positive electrode materials, performance, and application areas are diverse.

26650, strictly defined as the size of a single cell: diameter 26mm, height 65mm. The size of this cylindrical appearance may vary slightly among manufacturers in actual production, with different heights, heights, plumpness, and thinness, all referred to as 26650. But this difference will not be significant, the diameter will not exceed 27mm, and the height will not exceed 66mm. When a single battery cell is equipped with a support system and put into use, it is called a 26650 lithium battery. If multiple lithium cells or lithium batteries are combined together, it is called a lithium battery pack, or more precisely, a 26650 lithium battery pack.

Like 18650 lithium batteries, 26650 lithium batteries can also use different positive electrode materials. Based on the current application situation in the market, there are basically 26650 ternary lithium batteries and 26650 lithium iron phosphate batteries. The difference between the two is also the general difference between ternary lithium batteries and lithium iron phosphate batteries. The former has the advantage of high capacity and voltage platform, while the latter has the advantage of safety and high starting current. Considering that 26650 lithium batteries are mostly used for equipment startup, the main application is 26650 lithium iron phosphate batteries, which have obvious advantages in safety and price.

Many factories produce 26650 lithium iron phosphate batteries, although they have personalized differences, their basic parameters should comply with international standards. We have chosen the relevant parameters of Dongguan Juda Electronics Co., Ltd., a custom lithium battery manufacturer, to give everyone a visual and general understanding of the 26650 lithium battery. The company's 26650 lithium battery has a maximum size of 26.4 * 65.8mm, a nominal capacity of 3000mAh, a nominal voltage of 3.2V, a charging and discharging cut-off voltage of 3.65V and 2.5V respectively, a standard charging and discharging current of 1500mAh, and a maximum capacity of 1C charging and 1.5C discharging. The operating temperature is -10 ℃ to+60 ℃.

The 26650 lithium iron phosphate battery has stable charging and discharging performance, high temperature resistance, and a cycle life three times that of ternary materials. Due to its ability to charge and discharge large currents, it is extremely suitable for strong light flashlights, mining lamps, instruments, and other devices. Moreover, this advantage allows it to develop towards large-scale development, such as the mature technology of the 26650 power type lithium iron phosphate battery in Dongguan.
