About lithium battery winding machine? The important technology of lithium-ion battery winding equipment is to control the tension of the separator and plate and to wind at a constant speed. The quality of plate tension control directly determines the quality of battery production. The quality of the tension also directly affects the balance and production capacity of the battery winding…

About the slitting machine? Lithium battery electrolyte is an organic substance without water molecules. If the water content is too high, the product will be scrapped, the quality will deteriorate, and even the product will explode. Therefore, before the battery is filled with liquid and sealed, it must be vacuum baked. This is necessary, and the purpose is to remove…

About the slitting machine? The pole piece slitting machine is the equipment for slitting the rolled battery pole piece according to the battery specification. Slitting type: 1. Disk shearing and cutting. 2. Die punching. 3. Laser cutting of lithium-ion battery pole pieces. Among them, laser energy and cutting moving speed are two important process parameters, which have a great influence…

What are the requirements for the edge after slitting? The pole piece encounters shear failure during slitting, and the flatness of the edge after slitting (no burr, no buckling) is the key to inspecting the performance of the slitting machine.  During the cutting process of lithium-ion batteries, the quality of the cutting edge of the pole piece has an important…

About copper foil? Copper foil is a key material for the negative electrode of lithium-ion batteries, which has an important impact on the energy density and other properties of the battery. Copper foil and aluminum foil have the advantages of good electrical conductivity, formed oxidation protective film, soft texture, good adhesion, mature manufacturing process, and relatively low price. Therefore, they…

About conductive agent? The key material in the positive electrode of lithium battery-aluminum foil. Battery aluminum foil is used as a current collector for lithium-ion batteries. Typically, the lithium-ion battery industry uses rolled aluminum foil as the positive electrode current collector. Advantages of carbon-coated aluminum foil in lithium battery applications: Inhibit battery polarization, reduce thermal effects, and improve rate performance….

About conductive agent? The conductive agent is to ensure that the electrode has good charge and discharge performance. A certain amount of conductive material is usually added when the pole piece is made, and it plays the role of collecting micro-current between the active material and between the active material and the current collector to reduce the The contact resistance…

About adhesive? Lithium (Lithium) is a metal element located in Group IA of the second period of the periodic table. The element symbol is Li. Its atomic number is 3 and its atomic weight is 6.941. The corresponding simple substance is a silver-white soft metal with the smallest density Metal. Due to the most negative electrode potential, lithium is the…

About adhesive? The binder is an auxiliary material for dispersing and binding in the battery. There is a battery binder inside the battery that accounts for less than 1~2%. Because some characteristics of the binder polymer have unexpected effects on battery performance. The binder mainly affects the kinetics of the battery, that is, the conduction of electrons and ions. The…

About MWD? MWD means “Measure While Drilling”, which originally meant measuring the main parameters of borehole trajectory while drilling, including: well inclination angle, azimuth angle, tool face angle and auxiliary parameters such as temperature, etc. Measurement While Drilling (or MWD) is a type of logging that incorporates measurement tools into the drillstring and provides real-time information to help guide the…
