Lithium battery number meaning and naming method analysis

There are two basic naming methods for lithium batteries: one is taken from the size of the battery, and the other is taken from the cathode material of the lithium battery. The classification of these two basic lithium battery naming methods is based on commonality and has general characteristics. For example, the 26650 lithium battery is classified and named from the size, so it has a common shape, and its cathode material, performance and use range are diversified. The strict meaning of 26650 lithium battery refers to the size of a single cell: 26mm in diameter and 65mm in height. The size of the appearance of this cylinder will be slightly different due to the actual processing of each manufacturer. 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 battery cell with the support system is put into use, that is, the 26650 lithium battery. If multiple lithium batteries or lithium battery packs are put together, 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 conditions, 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 26650 lithium iron phosphate battery. The general difference of lithium iron phosphate batteries. The former has the advantages of high capacity and voltage platform, and the latter has the advantages of safety and high starting current. The combination of 26650 lithium battery is mostly used in the actual situation of equipment startup, so the 26650 lithium iron phosphate battery is the most important use, and the advantages of this type of battery in terms of safety and price are clear. Many lithium battery manufacturers will process 26650 lithium iron phosphate batteries. Although they have different shapes and battery material formula ratios, the basic parameters should comply with international standards. In order to have an image and general understanding of the 26650 lithium battery. The numerical meaning of the 26650 lithium battery is that the maximum size 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 1C. Charging and 1.5C discharging, working temperature is -10℃~+60℃. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
