26650 lithium battery 26650 lithium battery detailed introduction
There are two basic methods for naming lithium batteries. One method is taken from the positive electrode material of the lithium battery, and the other is taken from the size. These two basic classifications are based on common characteristics and have general characteristics. In addition, there are classifications taken from a certain performance or application, which are based on personality and have 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 diversified.
26650, whichever is strictly defined, means that the size of a single cell is 26mm in diameter and 65mm in height. The size of the appearance of this cylinder varies slightly between manufacturers in actual production. The so-called: tall, short, fat and thin, they are all called 26650. But this difference will not be great, the diameter will not exceed 27mm, and the height will not exceed 66mm. The single cell with the support system is put into use, which is a 26650 lithium battery. If it is a combination of multiple lithium cells or lithium batteries, it is called a lithium battery pack. To be more precise, it is a 26650 lithium battery pack.
Like 18650 lithium batteries, 26650 lithium batteries can also use different cathode materials. According to the current market applications, there are basically 26650 ternary lithium batteries and 26650 lithium iron phosphate batteries. The difference between the two is also ternary lithium batteries and The general difference of 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. Combining with 26650 lithium battery is mostly used in the actual situation of equipment startup, so the main application is 26650 lithium iron phosphate battery, and this type of battery has obvious advantages in safety and price.
Many factories will produce 26650 lithium iron phosphate batteries, although they have individual differences, but the basic parameters should comply with international standards. Below we choose to customize the relevant parameters of the lithium battery manufacturer Dongguan Juda Electronics Co., Ltd. to give everyone an image and general understanding of the 26650 lithium battery. The size of the company’s 26650 lithium battery: the largest can be 26.4*65.8mm, the nominal capacity is 3000mAh, the nominal voltage is 3.2V, the charge-discharge cut-off voltage is 3.65V and 2.5V, the standard charge-discharge current is 1500mAh, and the maximum can be charged at 1C And 1.5C discharge, working temperature is -10℃~+60℃.
The 26650 lithium iron phosphate battery has stable charging and discharging performance, high temperature resistance, and its cycle life is 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, etc., and this advantage To enable it to develop to large-scale development。
