26650 lithium battery details

There are two basic methods for naming lithium batteries. One method is taken from the positive electrode material of lithium battery, and the other is taken from the size. The two basic classifications are based on commonality and have general characteristics. There are also classifications taken from a certain performance or application, starting with personality and having specific characteristics. The 26650 lithium battery is classified in terms of size and thus has a common shape, and its cathode material, performance and application fields are diversified.

26650 is strictly defined as the size of single cell: 26mm in diameter and 65mm in height. The size of the cylindrical appearance of each cylinder will be slightly different in actual production. The so-called: high, short, thin and thin, are called 26650. But the difference is not too big, the diameter will not exceed 27mm, and the height will not exceed 66mm. The single cell is equipped with a support system, which is the 26650 lithium battery. If it is a combination of multiple lithium batteries or lithium batteries, it is called a lithium battery. More precise is the 26650 lithium battery.

Like the 18650 lithium battery, the 26650 lithium battery can also use different cathode materials. According to the current application on the market, there are basically 26650 ternary lithium batteries and 26650 lithium iron phosphate batteries. The difference between the two is also the 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 advantages of safety and high starting current. Combined with the 26650 lithium battery is mostly used in the actual situation of equipment startup, so the 26650 lithium iron phosphate battery is the main application, and the advantages of such batteries in terms of safety and price are obvious.

Many factories produce 26650 lithium iron phosphate batteries. Although they are individualized, the basic parameters should conform to international standards. Below we choose the relevant parameters of the custom lithium battery manufacturer Dongguan City, the largest electronic company, so that everyone has an image of the 26650 lithium battery and a general understanding. The company's 26650 lithium battery dimensions: the largest can be 26.4 * 65.8mm, the nominal capacity of 3000mAh, the nominal voltage of 3.2V, charge and discharge cutoff voltage are 3.65V and 2.5V, the standard charge and discharge current 1500mAh, the maximum can be charged 1C And 1.5C discharge, working temperature is -10 ° C ~ +60 ° C.

26650 lithium iron phosphate battery has stable charging and discharging performance, high temperature resistance, and cycle life is three times that of ternary material. Because it can charge and discharge with large current, it is very suitable for glare flashlights, miner's lamps, instrumentation, etc. It can be developed to a large scale, such as Dongguan's Large 26650 power type lithium iron phosphate battery technology has matured.
