18650 battery 3.7v 3500mah

　　What is the difference between 18650 battery 3.7v 3500mah and ternary battery?

　　Ternary polymer lithium battery refers to the ternary battery cathode material using lithium nickel cobalt manganate (Li) or lithium nickel cobalt aluminate (NiCoMn). The ternary composite battery cathode material is composed of nickel salt, cobalt salt, and manganese salt. Composition, in which the proportion of nickel, cobalt and manganese can be adjusted according to actual needs. Compared with lithium cobalt oxide batteries, positive-grade batteries made of ternary materials have a higher safety factor, but the working voltage is too low, and there will be obvious signs when using mobile phones. I feel that (the cut-off voltage on mobile phones is generally at the upper and lower levels), the cut-off voltage on mobile phones is obviously not enough.

　　18650 battery 3.7v 3500mah refers to a lithium battery using lithium iron phosphate as the positive electrode material of the battery. The main battery cathode materials include lithium cobalt oxide batteries, lithium manganate batteries, lithium nickel oxide, ternary materials, lithium iron phosphate batteries, etc. This lithium cobalt oxide battery is the cathode material used in most batteries currently used in lithium batteries.

　　Comparison of characteristic parameters between ternary lithium batteries and lithium iron phosphate batteries: low temperature characteristics.

　　The low-temperature characteristics of iron lithium batteries are a drawback. At temperatures of 0-5 degrees in Jiangsu and Zhejiang areas in winter, their performance is about 75% of that in summer. However, high-power cars perform even worse under high current conditions. At the same temperature, the temperature of ternary rechargeable batteries is about 90% of that in summer. There is a certain decrease, but it is not significant. In the northeastern region, rainfall will decrease slightly. Consumers in different regions will consider this when choosing lithium battery raw materials.

　　The technical parameters of ternary lithium batteries and lithium iron phosphate batteries are: volume.

　　The capacity of the lithium iron battery is insufficient. Under the same specifications, iron lithium batteries can hold 10AH, and ternary lithium batteries can generally hold more than 15AH. This is very different from today's high-power sliding friction. Take Piao bicycles as an example. Vehicles equipped with iron lithium batteries are generally around 72V80AH. To install 100AH, you need to make a lot of modifications. If you switch to a ternary battery, it is easier to install 150AH, and it is easier to install 200AH. It would be too difficult. For users who need to charge and discharge with large currents for a long time, the shortcomings of lithium iron batteries are very obvious. Whether it is the output charging and discharging current or the mileage, it is not even a little bit worse.
