There are two basic methods for naming lithium batteries. One way is taken from the positive electrode material of the lithium battery, and the other is taken from the size. These two primary classifications are based on commonality and have general characteristics. In addition, there are classifications taken from a specific performance or application, which start from the aspect of personality and have particular features. The 26650 lithium battery is classified in size, so it has a familiar shape, and its cathode material, 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 are all called 26650. But this difference will not be significant, 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 26650 ternary lithium batteries and 26650 lithium iron phosphate batteries. The difference between the two is also ternary lithium batteries and The general contrast of lithium iron phosphate batteries. The advantage of the former lies in the high capacity and voltage platform, while the latter's edge lies in the safety and high starting current. Combining with 26650 lithium battery is mainly used in the actual situation of equipment startup, so the main application is 26650 lithium iron phosphate battery. This type of battery has apparent advantages in safety and price.
Many factories will produce 26650 lithium iron phosphate batteries. Although they have individual differences, the fundamental 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 make everyone have an image and general understanding of the 26650 lithium battery. The size of the company's 26650 lithium battery: The maximum 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 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 released with a high current, it is highly suitable for strong light flashlights, miner's lamps, instruments, etc., and this advantage Make it possible to develop to large-scale development, such as Dongguan Juda's 26650 power-type lithium iron phosphate battery technology has matured.
