Is there any particular reason why the current collectors of the positive and negative electrodes ar

Performance Advantages of Carbon Coated Aluminum Foil/Copper Foil 1. Greatly improves the consistency of battery usage and greatly reduces battery costs. For example: · Significantly reduce the increase in dynamic internal resistance of the cell; · Improve the consistency of the battery pack voltage difference; · Extend the life of the battery pack; · Significantly reduce the cost of battery pack. 2. Improve the adhesion between active materials and current collectors and reduce the manufacturing cost of pole pieces. For example: Improving adhesion of materials and cathode collectors using aqueous systems; Improving the adhesion of cathode materials and collectors at the nanometer or submicron scale; Improve the adhesion of lithium titanate or other large capacity anodic materials and collectors; Improve the qualification raten of pole pieces and reduce the cost of manufacturing pole pieces. After using carbon-coated aluminum foil, the adhesion of the pole piece is increased from the original 10 gf to 60 gf (using 3M tape or the hundred grid knife method), and the adhesion is significantly improved. 3. Reduce bias, increase rate and gram capacity, and improve battery performance. For example: · Partially reduce the proportion of binder in the active material and increase the capacity in grams; · Improve the electrical contact between the active material and the current collector; · Reduce polarization and improve power performance; 4. Protect the current collector and extend battery life. Such as: · Prevent corrosion and oxidation of current collector; · Increase the surface tension of the current collector and improve the coating performanceeasy current collector ent; · Can replace the more expensive engraved sheet or replace the original standard with a thinner sheet. foil.

Hello, Hanye's investment in lithium battery copper foil in Deyang will be put into production in September 2020. Copper foil for lithium batteries is an important component of lithium batteries and forms the conductive medium between the electrolyte and the cathode material. Its quality directly affects the performance and lifespan of lithium batteries. Hanye is an enterprise specializing in the research, development, production and sales of lithium battery copper foil, and occupies a leading position in the domestic lithium battery copper foil industry. In order to meet market demand, Hanye has invested in constructionn of a production line for copper foils for lithium batteries in Deyang, with an annual production of 5,000 tons. The production line adopts advanced production technology and equipment and can produce lithium battery copper sheets of various specifications and. qualities. After several production trials and debugging, the production line was officially put into production in September 2020, providing higher quality lithium battery copper foil products for the development of the lithium battery industry. The commissioning of Hanye has also injected new impetus into the economic development of Deyang City and promoted the growth and improvement of the local lithium battery industry.

The difference between high performance composite copper foil and lithium battery composite copper foil

Because lithium batteriesLithium cell phones are made of layers of metal foil and insulating paper wrapped around each other. ?

As the current collector of lithium batteries, the thickness of the copper foil of lithium batteries is generally between 7 and 20 μm. At present, the thickness of the copper foil equipped with new energy vehicles is 8-12μm, and the copper foil mass of the whole vehicle reaches more than 10kg. The smaller the thickness of the copper sheet of the lithium battery, the lighter the weight of the battery will be.

At the same time, thinner copper foil for lithium battery also means lower resistance and the performance of the battery will also be improved. Therefore, reduce the quality of copper foil on the battery, reduce the raw material cost of copper foil, and provide high density.Higher energy efficiency has become a key issue for copper foil in power lithium batteries.key.

Lithium battery is a type of battery that uses lithium metal or lithium alloy as positive/negative electrode materials and uses non-aqueous electrolyte solution. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912.

In the 1970s, M. S. Whittingham proposed and began studying lithium-ion batteries. Since the chemical properties of lithium metal are very active, the processing, storage and use of lithium metal are subject to very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable.

The difference between high performance composite copper foil and lithium battery composite copper foil is: Firstly, the production process is different. Second, the mechanical properties are different. Advantages of composite copper foil Copper foil, as the negative electrode current collector of lithium batteries, mainly plays the role of carrying the negative electrode active material + collecting current. Traditional copper foil uses 99% high purity electrolytic copper as the main material, which has the advantages of strong electrical conductivity, good heat dissipation and low manufacturing cost.
