The naming method and number of lithium batteries

　　The strict definition of 26650 lithium batteries refers to the size of the single cells: 26mm in diameter and 65mm in height. The size of this cylindrical body will be slightly different because each manufacturer will be slightly different in actual production. But this difference will not be very large, the diameter will not exceed 27mm, and the height will not exceed 66mm. The single battery is equipped with a 26650 lithium battery. If it is a lithium battery or a lithium battery combination, it is called a lithium battery pack. It is more precise.

　　Like 18650 lithium batteries, 26650 lithium batteries can also use different positive electrode materials. According to the current application of the market, the basic 26650 trifangua 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 advantage of the former is the high capacity and voltage platform, and the advantage of the latter lies in high security and high start current. Combining 26650 lithium batteries is mostly used in the actual conditions of the device, so the main application of 26650 lithium iron phosphate batteries, and the advantages of such batteries in terms of safety and price are obvious.

　　Many lithium battery manufacturers will produce 26650 lithium iron phosphate batteries. Although they have different shapes and formula proportion of battery materials, the basic parameters should meet international standards. In order to have a image and general understanding of the 26650 lithium battery. The number of 26650 lithium batteries is the maximum size of the shape, the maximum size can be 26.4*65.8mm, the nominal capacity is 3000mAh, the nominal voltage is 3.2V, the charging and discharge interception voltage is 3.65V and 2.5V, respectively. Charging and 1.5C discharge, the operating temperature is -10 ° C ~+60 ° C.
