What is the 26650 Lithium Battery?

There are two basic naming methods of lithium battery, one is from the cathode material of lithium battery, the other is from the size. These two basic classification is from the common aspect, with general characteristics. There are also categories derived from certain properties or applications, starting from personality, with specific characteristics. 26650 lithium battery is classified in terms of size, so it has a common shape, and its cathode materials, performance and application fields are diversified.

26650, its strict definition refers to the size of the single cell: diameter 26mm, height 65mm. The size of the cylindrical appearance of each manufacturer in actual production will be slightly different, the so-called: different height, height, fat and thin, are called 26650. However, the difference is not very big, neither diameter more than 27mm, nor height more than 66mm. Single cell with support system into use, is 26650 lithium battery, if it is a plurality of lithium cell or lithium battery combination together called lithium battery pack, a more accurate statement is 26650 lithium battery pack.

Like 18650 lithium battery, 26650 lithium battery can also use different cathode materials, according to the application of the current market, the basic 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 advantage of high capacity and voltage platform, while the latter has the advantage of high safety and starting current. Considering the fact that 26650 lithium battery is mostly applied to equipment start-up, 26650 lithium iron phosphate battery is the main application, and this kind of battery has obvious advantages in safety and price.

Many factories will produce 26650 lithium iron phosphate batteries, although they have personalized differences, but the basic parameters should meet international standards. Following we choose to customize the lithium battery manufacturer Dongguan Juda Electronics Co., LTD. Related parameters to make you have a picture of 26650 lithium battery understanding and general understanding. The company 26650 lithium battery dimensions: The maximum can be 26.4*65.8mm, nominal capacity 3000mAh, nominal voltage 3.2V, charge and discharge cut-off voltage is 3.65V and 2.5V, standard charge and discharge current 1500mAh, the maximum can be 1C charge and 1.5C discharge, working temperature is -10℃~+60℃.

26650 battery charging and discharging lithium iron phosphate performance stability, high temperature resistant, cycle life is 3 times of that of three yuan, because of its large current charge and discharge, thus to strong light flashlight, miner's lamp, instrumentation, such as extremely apply, and this advantage can make it to the large-scale development, such as dongguan major big 26650 power type lithium iron phosphate battery technology is ripe.
