How does laboratory ball mill work? A laboratory ball mill consists of a cylindrical shell that rotates around its axis, and the shell is partially filled with balls. The grinding media, which can be made of steel, stainless steel, ceramic, or other materials, is added to the shell to provide a grinding action on the material being processed. The rotation of the shell causes the balls to move in a circular motion, creating friction and impact forces that grind the material into smaller particles. The size of the ground material is dependent on the size of the balls, the speed of rotation, and the amount of time the material is allowed to be ground. To obtain a fine powder, the mill can be run for a longer period of time, and the balls can be made of a smaller size. Conversely, to obtain coarser particles, the mill can be run for a shorter period of time and the balls can be made of a larger size. The ball mill operates on the principle of impact and attrition: the size reduction is done by impact as the balls drop from near the top of the shell. The balls are lifted up the side of the mill and then they cascade down, or roll down, to the bottom. This helps to reduce the size of the material through a combination of impact and abrasion. The ball mill can be used for wet or dry grinding, and it is widely used in the production of ceramics, pigments, pharmaceuticals, and other materials. In a laboratory setting, ball mills are usually operated at lower speeds, and the grinding time is typically longer than in industrial applications.

Introduction and Characteristics to Lithium Battery Electrode Slitting During the cutting process of lithium-ion battery, the quality of the cutting edge of the electrode plate has an important impact on the performance and quality of the battery, including: (1) burr and impurities will cause short circuit in the battery, causing self-discharge and even thermal runaway; (2) The dimension accuracy is poor, which can not guarantee that the negative pole completely wraps the positive pole, or the diaphragm completely isolates the positive and negative pole pieces, causing the battery safety problem; (3) Material thermal damage, coating peeling, etc., resulting in material deactivation and inability to use; (4) The unevenness of the trimming leads to the non-uniformity of the electrode charge and discharge process. Therefore, the cutting process of lithium-ion battery electrode should prevent these problems and improve the process quality. 1. Disc shearing The disc slitting is mainly composed of upper and lower disc cutters, which are installed on the cutter shaft of the slitter. The rolling shear principle is used to cut the positive and negative pole plates with a thickness of 0.01~0.1mm. 2. Die punching/slitting The die-cutting process of lithium ion battery electrode is divided into two types: (1) Die-cutting of wood plate, the sharp blade is installed on the wood plate, and the blade is used to cut the electrode under certain pressure. This process mold is simple and low cost, but the punching quality is not easy to control, and it is now being phased out. (2) The metal die is used for punching, and the pole piece is cut by using the very small gap between the punch and the lower die. There’s also battery slitting machine can slit electrode piece into certain width strips. The coating particles are connected together by adhesive. During the punching process, the coating particles are peeled off under stress, and the metal foil undergoes plastic strain. After reaching the breaking strength, cracks appear, and the cracks grow and separate. The section of metal material punching parts is divided into four parts: angle collapse, shear zone, fracture zone and burr. The wider the shear band of the section, the smaller the height of the collapse angle and burr, and the higher the section quality of the punched part. 3. Laser cutting of lithium ion battery electrode There is a problem of tool wear in disc cutting and die cutting, which is easy to cause process instability, resulting in poor cutting quality of electrode pieces, and the battery performance degradation. Laser cutting has the characteristics of high production efficiency and good process stability, and has been applied to the cutting of lithium-ion battery electrode plates in industry. Its basic principle is to use a high power density laser beam to irradiate the cut battery electrode plates, so that the electrode plates are quickly heated to a high temperature, and rapidly melt, vaporize, ...

Application of Wire Bonding Technology in Power Battery Field 1. What is aluminum wire bonding ultrasonic welding technology? Aluminum wire ultrasonic welding is actually a wire bonding technology using aluminum as metal wire. Wire bonding is a primary internal interconnection method, which is used as a primary internal interconnection method to connect to the actual bare chip surface or device logic circuit. This connection method connects the logic signal or chip electrical signal with the outside world. 2. The application of wire bonding method Wire bonding machine has been widely used in microelectronics and power electronics since 1970. At present, wire bonding technology has a new application field, that is, the growing field of electric vehicles, especially in battery connection. In the production process of some electric vehicles, wire bonding technology is used to connect battery packs. TESLA is a typical representative company using this technology. 3. What are the advantages of wire bonding process? Traditional brazing and fusion welding technologies have been used for many years, and there are some disadvantages. For example, the generation of thermal stress, cleaning problems after welding, lack of flexibility and difficulty in quality control. Bonding's wire welding and strip welding perform much better than traditional welding in this respect, and can control every welding point well, without any adverse effect on the production process. 1) When aluminum wire welding or aluminum strip welding is used, it can be conducted at room temperature. No external temperature is required, and the temperature of the welding zone will not rise during ultrasonic friction welding. Other traditional welding methods require heating to melt the metal. 2) Wire bonding is a clean welding technology and does not require any post welding cleaning. After the traditional welding technology, there will be some residual flux or molten metal explosive that needs to be removed to avoid reliability problems. However, wire bonding needs to be cleaned only when there are some pollutants or stubborn oxides on the surface. 3) Wire bonding has good flexibility and strong compatibility, including low gold wire height, multi pin selection, large working range, ribbon or round wire selection. 4) The metal wire can have good direction flexibility, and can control the mismatch between a variety of thermal expansion parameters. 5) Different from spot welding machine. The wire bonding machine can be directly used as the fuse process in the lead wire connection process, eliminating the need to use resistance welding to weld nickel sheets, simplifying the production process and reducing equipment investment. Acey new energy is a professional supplier of aluminum wire bonding equipment and other battery making machineries for different cell kind. Welcome to send us your inquiries

How Does Ultrasonic Spot Welding Machine Work? In the production process of the lithium-ion battery cell, the cell is composed of multiple layers of electric core electrode sheets. Each layer of electric core foil stretches out a layer of lug foil. After the cell sheets are aligned, the lug foil is also pasted and aligned together. It is necessary to weld the electric core sheets together to form the cell, and the lug foil is welded together to form the lug. Because the lug foil is very thin, only about 001mm, the traditional method is ultrasonic welding. During welding, the lower part of the superposed lug foil is padded with the upper bottom die as a support, the welding head of the ultrasonic spot welding machine is pressed on the superposed lug foil, and a certain pressure is applied to the lug foil through the welding head, then the ultrasonic welding device is started, and the welding head directly outputs the ultrasonic, realizing the resonance of the atoms on the adjacent lug foil under high-frequency vibration, so as to combine the lug foil. Another traditional welding method is secondary welding, that is, the superposed lug foils are initially welded by ultrasonic welding device to achieve the initial combination of lug foils, and then the ultrasonic welding device is used for secondary welding again to make the lug foils fit firmly. Ultrasonic welding technology for battery lug The high-frequency vibration wave is transmitted to the two metal surfaces to be welded. Under pressure, the metal surfaces are used to rub against each other to form the fusion between molecular layers. Its advantages are fast, energy saving, high fusion strength, good conductivity, good thermal conductivity, non sparking, and close to the cold state Ultrasonic welding of battery lug It is applied to the welding of battery positive and negative lug, the welding of terminal to harness, and the welding of terminal to terminal. Capacitor positive and negative electrode welding. Sheet to sheet welding, sheet to plate welding, sheet to line welding, line to line welding, plate to line welding, riveting welding.
