26650 Lithium Battery

There are two basic methods for naming lithium batteries. One method is from the positive electrode material of the lithium battery, and the other is from the size. These two basic classifications are based on common characteristics and have general characteristics. In addition, there is a classification from a certain performance or application, which is based on personality and has specific characteristics. The 26650 lithium battery is classified in terms of size, so it has a common shape, and its cathode materials, performance and application fields are diverse.

26650, the strict definition means that the size of the single cell is 26mm in diameter and 65mm in height. The size of this cylindrical appearance varies slightly among manufacturers in actual production. The so-called: tall, short, fat, and thin are called 26650. But this difference will not be very large, the diameter will not exceed 27mm, and the height will not exceed 66mm. The single battery cell is equipped with a support system and is put into use. It is a 26650 lithium battery. If it is a combination of multiple lithium batteries or lithium batteries, it is called a lithium battery pack. More precisely, 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 ternary lithium battery and The general difference between lithium iron phosphate batteries. The former has the advantage of high capacity and voltage platform, the latter has the advantage of safety and high starting current. The combination of 26650 lithium batteries is mostly used in the actual situation of device startup, so 26650 lithium iron phosphate batteries are the main application, and the advantages of such batteries in terms of safety and price are obvious.

Many factories will produce 26650 lithium iron phosphate batteries, although they have different personalization, but the basic parameters should meet international standards. 26650 lithium battery size: maximum 26.4 * 65.8mm, nominal capacity 3000mAh, nominal voltage 3.2V, charge and discharge cut-off voltages are 3.65V and 2.5V, standard charge and discharge current 1500mAh, maximum 1C charge and 1.5 C discharge, working temperature is -10 ℃ ~ + 60 ℃.

The 26650 lithium iron phosphate battery has stable charge and discharge performance, high temperature resistance, and a cycle life that is three times that of the ternary material. Because it can charge and discharge with large current, it is extremely suitable for strong light flashlights, miner's lamps, instruments, etc., and this advantage So that it can develop to a large scale
