What is the important difference between 18650 lithium ion battery and 26650 lithium ion battery?

What is the difference between 18650 lithium ion battery and 26650 lithium ion battery? 26650 lithium ion battery and 18650 lithium ion battery are cylindrical lithium ion batteries. Combining the excellent capacity characteristics and high consistency of the 26650 lithium ion battery, as well as the excellent structural design and mature manufacturing practice foundation of the cylindrical battery, the 26650 lithium ion battery will gradually replace the 18650 lithium ion battery in the application of power lithium batteries. An overview of the 26650 lithium ion battery 26650 lithium ion battery. JPG26650 type, the battery diameter is 26mm, length 65mm, cylindrical battery. Generally refers to lithium-ion batteries, including lithium primary batteries and lithium-ion batteries. Commonly used nickel cobalt manganese anode materials, lithium iron phosphate lithium ion battery materials-inr26650-3.6v-4500mah, ifr26650-3.2v-3200mah. The 26650 lithium-ion battery is a cylindrical lithium-ion battery specification. It is suitable for electric tools, lighting, solar energy storage, electric vehicles, toys, instruments, UPS backup power supplies, communication equipment, medical equipment, military lamps and other fields. Overview of 18650 lithium ion battery The ordinary 18650 battery is divided into lithium ion battery and lithium iron phosphate battery. The rated voltage of the lithium ion battery is 3.7v, the charge cut-off voltage is 4.2v, the rated voltage of the lithium iron phosphate battery is 3.2v, the charge cut-off voltage is 3.6v, the general capacity is 1200mAh-3350mAh, and the general capacity is 2200mAh-2600mAh. The theoretical life of an 18650 lithium ion battery is 1,000 times. The density of the unit capacity is very large, so most of the laptop batteries, in addition, the stability of work in 18650 is very good, widely used in the electronic field: often used in high-end flashlights, portable power, wireless data transmission, electric thermal clothing, shoes And portable instruments, portable lighting, portable printers, industrial equipment, medical equipment, etc. What is the difference between 18650 lithium ion battery and 26650 lithium ion battery? 1. The rated capacity is different: IFR26650 lithium ion battery has a rated capacity of 3000mAh, and IFR18650 lithium ion battery has a rated capacity of 1100~1400mAh. 2. The diameter of the two batteries is different, the diameter of IFR26650 is 26mm, and the diameter of IFR18650 is 18mm. 3. Different reference quality: the production quality of IFR26650 lithium ion battery is 94 grams, and the production quality of IFR18650 lithium ion battery is 45 grams. 4. Different battery capacity; the volume of 26650 is larger than that of 18650. They have the same cell height and different cell diameters. The diameter of the 26650 is 26mm, and the diameter of the 18650 is 18mm. 5. Different battery capacity; 26650 battery capacity of the same battery material is greater than 18650. Assuming that the battery capacity of 26650 of the same material is generally around 5200mAh, the battery capacity of 18650 is more around 2600mAh. 6. Different application environment; 18650 lithium ion battery is widely used in lighting lamps battery, industrial lithium ion battery, power tool battery, electric bicycle battery, power lithium ion battery, 26650 lithium ion battery is widely used in solar street lamp integration lithium ion Batteries, energy storage stations, solar batteries, etc. 7.Different battery life; 18650, that is to say, refers to lasting 18mm and height 65mm, so that 26650 must be larger than 18650 than some larger volume, so there is more space to fill the material to achieve larger The current capacity of 18650 is 2200, 2600 is 3100mah, and the capacity of 26650 is generally 4000, 4200, 4500mah, resulting in longer battery life. With the demand for large-scale use of lithium-ion batteries, the replacement of 18650 lithium-ion batteries in the 3C era with larger-capacity 26650 lithium-ion batteries is bound to become a trend. At present, a considerable number of packaging companies and 3c integrated application suppliers have begun to use 26650 lithium-ion batteries, because the use of lithium-ion batteries in 26650 compared with 18650 can reduce packaging costs by about 30%. Very important to improve the company's profitability and market competitiveness. This is the difference between 18650 lithium ion battery and 26650 lithium ion battery. The 18650 lithium ion battery and the 26650 lithium ion battery are also completely different, but they can be modified with each other, but there are also differences. The thick barrel is equipped with a thin battery, and there is a conversion barrel that can thicken the 18650 battery and put it into the 26650 flashlight.
