Explain the assembly process and working principle of lithium iron phosphate battery in detail

The assembly process and working principle of lithium iron phosphate battery are introduced. Generally speaking, lithium iron phosphate batteries have safety problems of burning or even explosion during the assembly process. The root of these problems is the thermal control inside the battery, so non-professionals suggest not to assemble lithium-ion batteries. At the same time, the safety technology of lithium-ion batteries is constantly improving. Introduction to Lithium Iron Phosphate Battery Lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as the positive electrode material. Lithium-ion battery cathode materials mainly include lithium cobalt acid, lithium manganese acid, lithium nickel acid, three materials, and lithium iron phosphate. Lithium cobalt oxide is the negative electrode material for most lithium-ion batteries. Lithium iron phosphate battery. JPG Lithium Iron Phosphate Battery Assembly Process Choose a suitable battery, the battery type, voltage, and internal resistance must be matched. Please balance the battery before assembly. Cut electrodes and punch holes. 2. Calculate the distance according to the number of holes and cut the insulation board. 3. When the screws are complete, please use flange nuts to prevent the nuts from falling off. After the screws are connected, the battery pack can be fixed. 4. When connecting and welding wires and voltage collection wires (equalization wires), do not connect the external protection board to avoid accidentally burning the protection board. 5. Fix the insulating silica gel again. The silica gel will solidify after a while. 6. Install the protective plate. If you forgot to balance the battery before, this is the last chance before the battery is assembled. 7.Repair the entire battery pack with an insulating board, and use nylon straps and nylon straps for more endurance. Please note that we do not use the steel material shell. The shell is beautiful and strong steel material, but the battery is difficult to guarantee. Failure to dispose of some shells may reduce battery leakage and even cause accidents due to poor insulation. 8. After the battery is packaged as a whole, be sure to fix the battery and the protective plate. The actual measuring height of the battery is 1 meter, and it works normally. 9. The final packaging is completed, and both the output and the input are silica gel wires. The whole is a 48V20AH battery pack and lithium iron battery. The battery pack weighs 9 kg, which is half the weight of an equivalent acid battery. 10. After the completion of the tutorial, we conducted a post-assembly test on the lithium iron phosphate battery, which met our requirements. Relevant steps of lithium iron phosphate battery assembly technology 1. Battery material processing Some materials used in secondary batteries, such as lithium ion, require special treatment. The electrode should be processed at a high speed without damaging the fragile active material. In the electrolyte, special care must be taken to prevent the formation of precipitation and corrosive gases. 2. CAM unit If the machine is composed of a cylinder or AC servo drive with a cycle time of less than 1 second, even if the new machine is in good condition when it is installed, it will be difficult to maintain synchronization or stability for a long time. The cylinder reaches the end of the running distance in a short time, and the maintenance period is short. In mechanically manufactured cam mechanisms, this problem can be solved because all drives are held by the smallest motor. 3. Installation and foundation Establishing a solid mechanical device and foundation is very important for long-term stability. Installation and installation can reduce the start-up time by minimizing the deviation of transmission and transmission mechanism accuracy. In general, the use of aluminum frames is eliminated. Use the solid foundation of thick square wood and the manufacturing process of the pot to establish a stable foundation. Regarding a variety of different requirements, annealing can be carried out, and additional precision installation valve seats can be used. 4. Vacuum treatment not only has a simple vacuum chamber and heating furnace, but also the operation process of the vacuum chamber and the mechanism of liquid application equipment. Familiar with special vacuum equipment and components, such as vacuum pumps, pipes and valves. 5. Accurate positioning must have the required positioning technology and relevant experience, according to the requirements of mechanical positioning and image processing, to achieve an efficient processing calibration system. In order to maintain the accuracy for a long time, the control of the camera or the positioning station is realized, and the precise positioning is realized, including the installation design. 6. Laser welding, if possible, can be based on personal needs, such as CO2, YAG, LED, optical fiber and other laser knowledge and achievements, such as battery foil laser welding, throttle valve shell and bonnet welding, etc. Statement: Articles published on this site The pictures and content are from the Internet.
