18650 lithium battery 2600mah

　　Which kind of high temperature resistant 18650 lithium battery 2600mah is better?

　　Generally speaking, the working temperature of rechargeable batteries is around 40°C. However, in some practical application environments, the working temperature of rechargeable batteries is very hot, and the working temperature of rechargeable batteries can reach 75°C or above. This basically requires the use of high-temperature-resistant batteries. Battery. At present, there are three main types of high-temperature resistant batteries: polymer ternary lithium batteries, polymer lithium batteries and lithium iron phosphate batteries. So which high-temperature resistant 18650 lithium battery 2600mah is better? 1. High temperature resistant ternary 18650 lithium battery 2600mah Generally speaking, lithium batteries are not sensitive to the temperature in the 0-40°C area. If the temperature exceeds this area, the life and capacity of the 18650 lithium battery 2600mah will be reduced. Therefore, the operating temperature of lithium-ion batteries is generally 0-40°C. When the lithium-ion battery operates above 50℃ and below 60℃, the attenuation coefficient of the rechargeable battery decreases, and the service life reaches a certain attenuation coefficient. The temperatures of lithium batteries required by some special environments vary, and some can even operate normally in environments of hundreds of degrees Celsius. Ternary lithium batteries adapt to a wide range of operating temperatures, and their electric heat peak can reach 350°C-500°C.

　　The organic chemical properties of metallic lithium materials are very obvious during the heating process. The high-temperature resistance of rechargeable batteries is about 200°C. When the temperature is higher, the organic chemical properties of the ternary lithium material will be stronger, and the electrolysis of the 18650 lithium battery 2600mah will quickly light up.

　　2. High temperature resistant polymer 18650 lithium battery 2600mah Generally speaking, the working temperature of polymer 18650 lithium battery 2600mah is between -20℃-70℃. High and low temperatures can affect battery capacity. In addition, the chemical structure of the materials in rechargeable batteries will continue to be damaged and changed, severely affecting battery life. High temperature resistant lithium batteries can withstand heat up to 800 degrees. Generally speaking, the high temperature measurement of lithium is 200 degrees Celsius, 500 degrees Celsius and 800 degrees Celsius, but it is not easy to be exposed to such high temperatures in normal daily life. However, we can often see batteries damaged during charging or excessive use of electrical appliances. In particular, more and more smart products are equipped with battery bending, and only the detection service will have a 50-channel safety testing process. In this process, the new high-temperature engineering will make the battery bend 50 degrees, which will increase the service life of the battery. Life is unlikely to touch the battery. High lithium-ion batteries can generally be installed 300-500 times. It is better to partially discharge rather than fully charge a lithium-ion battery, and to minimize normal charge and discharge amounts. As soon as the rechargeable battery leaves the production line, the clock starts moving. Whether you use it or not, lithium only lasts two to three years. 3. High temperature resistant lithium iron phosphate battery High temperature resistant lithium iron phosphate battery pack can be divided into five levels for use in natural environments above 100°C, 125°C, 150°C, 175°C and 200°C. Currently, many of the major high-temperature cells are lithium/sulfonyl chloride and lithium/sulfonyl chloride used in electrophotocatalytic management systems. This is because these two systems have the largest energy density, wide temperature range, longest storage time, and highest operating frequency. The P-O bond in LifePO3 crystal is solid and cannot be dissolved. Even under high temperature or high pressure, it will not collapse like the Li-Co structure and will not produce strong oxides, a good safety factor. The maximum heating value of the rechargeable battery is 350,500 degrees Celsius, the operating temperature range is wide (-2075 degrees Celsius), and the volume is 100% at 60 degrees Celsius.
