Composite current collector is a new type of composite foil material with a sandwich structure of "metal conductive layer-PET/PP polymer material support layer-metal conductive layer" using organic polymer materials such as polymer PET/PP as the support layer, and metal (copper or aluminum) deposited on the upper and lower surfaces. Composite copper foil and composite aluminum foil are used as negative electrode current collectors and positive electrode current collectors to replace traditional electrolytic copper foil and rolled aluminum foil in lithium batteries. The advantages of composite current collectors are: ① Improve thermal runaway, thereby enhancing battery safety; ② Composite current collectors are lighter in weight, which is beneficial to improving the energy density of the battery; ③ Composite current collectors have fewer metal materials, which is beneficial to reducing raw material costs.

Combined with the actual needs of the domestic market, Hongtian Technology Co., Ltd. continues to strengthen independent research and development investment and is committed to creating efficient, stable and low-cost copper foil production equipment suitable for the Chinese market. Through technological accumulation and refined processes, Hongtian has successfully developed large-scale electrolytic copper foil cathode rollers and foil production machines, which can stably produce ultra-thin lithium battery copper foil and copper foil materials suitable for 5G high-frequency electronic information products.
This technological breakthrough not only fills the gap in the domestic market, but also greatly improves the production efficiency and precision of copper foil, and promotes the rapid development of lithium batteries, 5G communications and other high-tech industries. The company continues to promote the optimization and upgrading of technology, making the electrolytic copper foil production process not only internationally advanced, but also competitive in the industry, setting a new technical benchmark for the global copper foil equipment industry.
This innovative technology of Hongtian Technology Co., Ltd. is not only a leap forward for the domestic copper foil equipment industry, but also an important breakthrough in the development of global electrolytic copper foil equipment technology. Through these technological breakthroughs, the company has successfully achieved all-round independent control from equipment manufacturing to material production, ensuring the stability and consistency of products, while also reducing production costs and enhancing the international competitiveness of China's copper foil industry.
2. How did the key breakthrough of composite copper foil equipment promote the development of lithium batteries and 5G technology?
In today's world, lithium batteries and 5G communication technology have become key factors in promoting the development of emerging industries and modern society. As the core component of electric vehicles and portable electronic devices, lithium batteries have a growing demand for copper foil; and the widespread application of 5G technology requires higher performance copper foil materials. The requirements of these high-end applications for copper foil are not only reflected in thickness, but also in its conductivity, stability and surface flatness. Hongtian Technology Co., Ltd. has provided strong technical support to the industry through innovative research and development while meeting these needs.
One of the company's key breakthroughs in the field of composite copper foil equipment is the successful development of large-scale electrolytic copper foil cathode rollers and foil production machines with a diameter of 3 meters and a width of 1.82 meters. These large-scale equipment can not only stably produce high-end ultra-thin lithium battery copper foil (thickness up to 3.5um), but also produce 9um ultra-thin standard copper foil suitable for 5G high-frequency and high-speed electronic information products. Compared with traditional copper foil production equipment, Hongtian's equipment can significantly improve the production efficiency of copper foil and ensure the accuracy and quality of the product, meeting the high standards of copper foil materials in the lithium battery and 5G communication industries.
This technological breakthrough provides the lithium battery industry with higher-precision copper foil materials, ensures the high performance and long life of the battery, and also provides a foundation for the vigorous development of emerging industries such as electric vehicles. In the application of 5G technology, ultra-thin copper foil can not only improve signal transmission efficiency, but also reduce signal attenuation in high-speed data transmission, thereby improving the overall performance of communication equipment. Hongtian Technology Co., Ltd.'s equipment enables domestic companies to occupy a stronger market competitiveness in these cutting-edge technology fields and promotes the technological upgrading of the entire industry.
Hongtian continues to invest in research and development, and by improving production processes and technologies, the quality and stability of its products have reached international first-class levels. In the field of lithium batteries and 5G, copper foil materials produced with Hongtian equipment can better meet the diversified needs of future intelligent and automated products for copper foil materials, and promote the rapid development of the entire technology industry.
3. What are the advantages of localizing composite copper foil equipment?
The localization of composite copper foil equipment has important strategic significance for the Chinese market and the global copper foil industry. Hongtian Technology Co., Ltd.'s composite copper foil equipment was successfully localized, breaking the monopoly of imported equipment in the domestic market and bringing significant cost-effectiveness and technological independence. This breakthrough promoted the entire electrolytic copper foil industry development of the industry.
Localized equipment significantly reduces production costs. In the past, domestic companies often relied on imported equipment to produce high-precision electrolytic copper foil, which not only increased procurement costs, but also made equipment maintenance and technical support difficult. The localized equipment provided by Hongtian Technology Co., Ltd. not only reduces the initial cost of equipment procurement, but also reduces the reliance on external technology in the production process. Through independent research and development, Hongtian can more flexibly adjust the performance and parameters of the equipment to meet different market needs and improve production efficiency, thus improving the overall market competitiveness.
Localized equipment can bring greater technological autonomy. With the improvement of domestic R&D levels, Hongtian no longer relies solely on foreign technology and equipment, but relies on its own innovation capabilities to design and produce high-precision copper foil equipment suitable for the Chinese market and global markets. This means that Chinese enterprises have greatly enhanced their independent control over key technologies and equipment, and can respond more quickly to market changes, make rapid adjustments to products and technologies, and reduce their reliance on external technology.
Localized services and support for domestically produced equipment enable manufacturing companies to receive more timely and efficient help in equipment maintenance and technical support. Hongtian Technology Co., Ltd. has rich experience and mature systems in equipment after-sales service, maintenance and technical training, allowing customers to quickly solve problems in equipment use and avoid all the inconveniences caused by imported equipment.
Localization also promotes the upgrading and technological progress of the entire industrial chain. Through independent research and development and innovation, Hongtian not only improves its own technical level, but also drives the technological improvement of surrounding suppliers and partners. With the continuous improvement of technology and the continuous upgrading of equipment, the technical level of the entire electrolytic copper foil industry has gradually aligned with international standards, further enhancing the international competitiveness of China's manufacturing.
