Introduction to the technology of lithium -ion battery pack PACK automation production equipment. As we all know, from the entire process from the lithium -ion battery single battery cell to the automation module to the PACK production line, the degree of automation of the assembly line is an important factor that determines the quality and production efficiency of the product. Lithium -ion battery manufacturing equipment is generally three types: front -end equipment, middle -end equipment, and back -end equipment

Comparison of the performance of lithium -ion batteries and batteries Temperature tolerance: The working temperature of the common lithium-ion battery is -20-60 degrees Celsius, but generally the performance of lithium-ion battery after 0 ℃ will decrease, and the discharge capacity will be reduced accordingly. , Commonly 0 ~ 40 ° C. The temperature of the lithium -ion battery with special environment requirements is different, and some can even run normally in the environment of hundreds of degrees Celsius.(

What is the lithium ion battery pulse charging? What does pulse charging affect lithium ion batteries? The charging time and life of lithium -ion batteries have always been the bottleneck of electric vehicle applications. Traditional fast charging technology may shorten the cycle life of lithium -ion batteries. The polarization voltage is the external manifestation of the charging current in the electrochemical reaction effect of the battery. During the charging process, the polarization voltage will shorten the li

Detailed explanation of the characteristics of mobile assembly portable lithium -ion battery UPS power supply system. With the increasing degree of dependence on various electronic equipment, the computer rooms in many important places must supply temporary UPS power supply to ensure power supply. The UPS power supply system of mobile assembly lithium -ion battery The load capacity and maximum load power can be expanded arbitrarily. Detailed explanation of the characteristics of mobile assembly portable lithium

Uninterrupted power manufacturers tell you the difference between UPS power bids and long machines. UPS uninterrupted power supply is generally divided into long machines and bid machines. Long machines must be external battery packs (with a battery cabinet), and the standard machine must have a battery inside the machine. From practical and battery life, of course, long aircraft are better. Here, the uninterrupted power supply UPS manufacturer will tell you the difference between the long machine and the benchmark

What are the disadvantages of dual -machine redundant improvement of the reliability of the UPS power system? Dual -machine redundant means backup. One machine has problems, and the top of the other machine is to improve the reliability of the UPS power system. Usually two or more stand -alone single machines are used to form a dual or multi -machine UPS system, which improves the reliability of power supply power, so that the UPS interrupt power supply will not occur while the single UPS fails. What are the dis

What is the lithium -ion battery SEI film? The formation of lithium -ion battery SEI film. The SEI density of lithium-ion batteries is very good and low in impedance at -20 ℃. The thickness of the SEI is about 100-120nm. , LICO2-R, alcohol salt, and non-conductive polymer composition are multi-layered structures. The side of the electrolyte is porous, and the side of the electrode is dense. What is the lithium -ion battery SEI film? During the first charging and discharge of liquid lithium -ion batteries, the

The characteristics and needs of soft -pack lithium -ion battery material aluminum -plastic film. Aluminum -plastic film is a link with high technical difficulty in the field of lithium -ion battery material, and the comprehensive gross profit margin can reach more than 40%. There are three important types of lithium -ion battery packaging, namely cylindrical, square and soft bag. Compared with the same capacity steel shell lithium -ion battery, the weight of the same capacity is 40%lighter than the aluminum shell

Lithium iron phosphate ion batteries are the advantages of power lithium -ion battery packs. The application field of lithium iron phosphate cells is widely used. It can be said that "places" that can use batteries can be used in lithium iron phosphate cells. Due to the different manufacturing materials and different craftsmanship, there are many types. In terms of the choice of power lithium ion battery packs, the great advantages of lithium iron phosphate ion batteries have occupied the market. So what
