Analyze the application fields of low-temperature lithium battery packs and the correct use methods

Application field of low-temperature lithium battery pack and correct use method. Low-temperature lithium battery refers to the operating temperature below -20°C, and low temperature has an impact on the positive electrode, negative electrode, electrolyte, and adhesive of the lithium iron phosphate battery package. Companies and scientific research institutions in the industry are exploring and solving the low temperature resistance of lithium batteries, focusing on improving the existing anode and cathode technical materials, and creating conditions for the battery to work at low temperatures and increasing the battery's local environmental temperature. Low-temperature lithium battery pack application field In recent years, the application range of lithium battery has become more and more extensive. Lithium batteries are widely used in energy storage power systems such as water power, fire power, wind power, and solar power stations, as well as power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace and other fields. At present, lithium batteries have gradually expanded to electric bicycles, electric vehicles and other fields. Low-temperature lithium battery packs are widely used in aviation, aerospace, deep sea, power supply, cold zone emergency, strict manufacturing processes and methods, and can also be used for disaster relief, iron equipment, and on-board backup power supplies. Supply power for extreme environment equipment such as cold clothes and shoes. Application fields: military weapons, aerospace, vehicle-mounted bomb equipment, polar scientific research, cold emergency, power communications, public security, medical electronics, railways, ships, robots and other fields. Low temperature lithium battery. JPG Correct use of low-temperature lithium battery packs ●Lithium battery manufacturers must overcome some technical bottlenecks and develop a series of low-temperature lithium battery products. Ordinary lithium batteries have poor low temperature performance. Lithium iron phosphate batteries cannot drive electric vehicles at extremely low temperatures. ●The use of low-temperature lithium battery packs must pay attention to waterproofing. After some lower temperature equipment is used, it should be dried in time and stored at low temperature to prevent and prevent the occurrence of lithium battery family fire accidents caused by improper use. ●Lithium battery has low energy density, has the safety and storage function of conventional lithium battery, and has high energy efficiency and low energy efficiency. Low-temperature lithium battery packs should have the advantages of high discharge rate, stable product performance, high specific energy, and good safety. ●It should be noted that when using the lithium battery pack, although the battery factory has been activated, it enters the dormant state after a period of time, and the capacity at this time is in a virtual state. However, lithium batteries are easily activated. Only after about three normal charge and discharge cycles can the battery be activated and return to normal capacity. Due to the characteristics of lithium batteries, it has almost no memory effect. Therefore, do not use special methods or equipment to activate the new lithium battery in the user's mobile phone. ● Regarding the charging of lithium batteries, within a certain current range (1.5c0.5c), the charging time of lithium batteries cannot be shortened by improving the constant current value of the constant current and constant voltage charging method. ●Properly control the temperature of the lithium battery pack in a clean, dry and ventilated environment with a relative humidity of 0-40°C and a relative humidity of not more than 75%. Avoid contact with corrosive substances and keep away from fire and heat sources. ●The normal charging and discharging cycle of lithium battery is about 500~800 times. When the life of the lithium battery is over, the corresponding recovery and treatment shall be carried out according to local rules. Lithium battery packs have the characteristics of large storage capacity, stable operation, and basically no memory effect. It also has the advantage of adapting to ambient temperature. For example, thionyl chloride lithium battery, the operating temperature can be between -40 ℃ to +55 ℃. Of course, when the temperature drops to -40 degrees, the capacity will also change, which is 50% of the normal temperature. This shows that low temperature has a great influence on lithium batteries. It should be kept at room temperature for use as much as possible. The impact of low temperature on lithium batteries Current mobile phone batteries are generally lithium batteries, and the chemical reaction rate of the battery is affected by temperature. Using the mobile phone for a long time in a low temperature environment will slow down the chemical reaction of the battery, resulting in low battery discharge current and reducing the battery capacity.
