The surface treatment of battery conductive substrates with functional coatings is a breakthrough technological innovation. Carbon-coated aluminum foil and Carbon-coatedcopper foil is to coat dispersed nano-conductive graphite and carbon coated particles evenly and delicately on aluminum foil and copper foil. It can provide excellent static electrical conductivity, collect the micro current of the active material, which can greatly reduce the contact resistance between the positive and negative electrode material and the current collector, and can improve the adhesion between the two and reduce the adhesion The amount of agent used, in turn, significantly improves the overall performance of the battery. Performance advantages of conductive coating carbon-coated aluminum foil and copper foil: 1. Significantly improve the consistency of the battery pack and greatly reduce the battery composition cost. 2. Improve the adhesive force of the active material and the current collector, and reduce the manufacturing cost of the pole piece. 3. Reduce polarization, increase rate and gram capacity, and improve battery performance. 4. Protect the current collector and prolong the service life of the battery. Thank you for reading!

The glove box is a laboratory device for filling the box with highly pure inert gases and circulating filtration of active substances.Also known as vacuum glove box, inert gas protection box, etc.The main function is the removal of O2, H2O and organic gases The inert gas in the glove box is closed circulation by the circulation fan and purifier. H2O, O2 can be removed continuously. Auto Purging - The replacement of the atmosphere inside the glove box can be achieved automatically by the purging valves. Automatic Regeneration - H2O and O2 removal material can be regenerated. The regeneration process controlled by program. Pressure Control in the Glove Box - The pressure in the glove box is controlled automatically by the Programmable Logic Controller (PLC). Working pressure can be set between +10mbar and -10mbar. If the pressure goes over+/- 12mbar, the system will be protected automatically. Automatic Vacuum Pump Control - The vacuum pump will be activated automatically when necessary, and will turn off after a period of idle time.

For server days research we had finally finished this job. A new design battery winding machine,which you can used to winding different size battery by adjust the position of the winding needle. There have two way the battery cells core assembly : winding or stacking. The battery stacking type is to cut the cathode and anode electrode and the separator to a specified size, and then stack the anode piece, the separator, and the cathode piece into a small cell monomer, and then stack the small cell monomers in parallel to form a composition a large battery cell; the winding type is a process in which the electrode after slitting is fixed on the winding needle and the cathode, the anode and the separator are rolled into the cell as the winding needle rotates. The operation of the battery winding is relatively simple, and it can be completed quickly whether it is semi-automatic or fully automatic. The battery stacking process is highly complex, manual operation is time-consuming and laborious, and automation is difficult to industrialize due to equipment problems. In addition, in terms of cell quality control, the winding type is easier to control, while the stacking type is more difficult to achieve good consistency due to cumbersome process steps. Regarding consumer batteries, more attention is paid to the improvement of efficiency than battery capacity and performance, so customers will have demand for winding technology. However, for dynamic lithium batteries, the stacking process can better take advantage of the advantages of large cells, and it has advantages over winding in safety, energy density, and process control. At the same time, the lamination process can better control the cell yield The most important thing is to pursue high energy density, so the stacking process is the best choice in the future. Both the battery stacking machine and the battery winding machine can prepare large-capacity square batteries. From the perspective of the vehicle development platform, the manufacturing of the square batteries in the future will match the vehicle chassis. If you look at energy density and cruising range alone, large modules and large batteries are indeed the trend, stacking is more dominant than winding, but the essence of market competition is price. If stacking equipment can significantly reduce costs, the profit will be higher than winding, replacement may be close at hand.

Why is aluminum foil used for the cathode? It is mainly divided into three aspects. The first is the electrochemical aspect. As a metal material, aluminum has a middle activity. It will form an aluminum oxide protective film in the air, which has high electrochemical potential and good corrosion resistance; secondly, in terms of mechanical properties , easy to process, good mechanical strength, weldable and riveted, and good thermal and electrical conductivity; again in terms of cost, the reserve is large, the cost is low, it is not a heavy metal, and it is not a strategic resource; therefore, it has been used as a collector of cathode electrodes for so many years. 2) Inspection of aluminum foil: The inspection of incoming materials by general battery companies includes outer packaging, appearance, thickness, width, areal density, material, welding performance, tensile strength, elongation, etc., depending on the thickness and material of aluminum foil. There are internal testing standards, and the testing is relatively simple, so I won’t go into details here. 3) The technological development of aluminum foil: With the improvement of the energy density of power batteries, the aluminum foil as the current collector is getting thinner and thinner, so it is required to have lower impurity content, less self-discharge, better thickness uniformity, Higher surface tension, better bonding performance, thinner thickness, higher strength, higher conductivity, suitable elongation and other requirements. At the same time, in order to increase the content of active substances, aluminum foil surface coating technology It is also developing very quickly. The following will briefly introduce these new technologies. A. Coating technology: The use of functional coatings for surface treatment of battery conductive substrates is a breakthrough technological innovation. Carbon-coated aluminum foil is to coat dispersed nano-conductive graphite and carbon coated particles uniformly and delicately On aluminum foil. It can provide excellent static electrical conductivity, collect the micro current of the active material, which can greatly reduce the contact resistance between the material and the current collector, and can improve the adhesion between the two, which can reduce the use of adhesives In turn, the overall performance of the battery is significantly improved. B. Porous aluminum foil: With the development of technology, porous aluminum foil technology has also emerged, which can carry more active materials and make the contact between active material particles closer. As far as the current technology is concerned, porous aluminum foil has not been applied in large quantities, and there are still problems in coating, low tensile strength, rolling press broken tape, and large burrs leading to large self-discharge. Further research and solutions are needed. There are some small soft package data that can significantly increase the energy density, but we believe ...

Electrolytic copper foil is an important material for the manufacture of copper clad laminates (CCL), printed circuit boards (PCB), and lithium-ion batteries. In today's rapid development of the electronic information industry, electrolytic copper foil is called the "neural network" of electronic product signal and power transmission and communication.Why use copper foil for anode electrode of lithium battery? 1. Copper and aluminum foil has good conductivity, soft texture and low cost. 2. Copper foil and aluminum foil is relatively stable in the air. 3. The positive and negative potentials of lithium batteries determine the aluminum foil for the cathode electrode and the copper foil for the anode electrode.
