In the lithium-ion battery industry chain, copper foil, as a core conductive material, has its cleanliness directly impacting the battery's energy density, cycle life, and safety performance. As a leading global copper foil company, Defu Technology is deeply committed to the high-end manufacturing of lithium-ion battery copper foil, demanding the utmost cleanliness control throughout the entire production process. Recently, a complete set of FASMEI cleanliness testing equipment was successfully installed at Defu Technology, providing a robust quality defense for its high-end copper foil production with its professional full-chain testing capabilities, demonstrating the core competitiveness of FASMEI cleanliness testing equipment in the field of high-end new energy manufacturing.

In the manufacturing process of lithium-ion battery copper foil, the presence of tiny pollutants can lead to safety hazards such as internal short circuits in the battery. Therefore, cleanliness testing is a critical aspect of quality control. The complete set of FASMEI cleanliness testing equipment chosen by Defu Technology covers all core equipment from sample extraction and particle detection to data analysis, accurately capturing pollutant particles at each stage of copper foil production, and achieving comprehensive, high-precision monitoring of cleanliness indicators. With its mature core technology and high stability proven through long-term market validation, this equipment perfectly adapts to the precise testing scenarios of lithium-ion battery copper foil, fully matching Defu Technology's high-end quality control standards.

As a leading copper foil company, Defu Technology has always maintained rigorous standards in equipment selection. The choice of FASMEI stems not only from the equipment's high stability and precision but also from its cost-effectiveness. Compared to similar German testing equipment, the complete FASMEI solution effectively reduces the company's equipment procurement and maintenance costs while ensuring testing performance. In addition, the professional technical service team from Infiro provided Defu Technology with customized installation, commissioning, and operational training, ensuring the equipment's rapid deployment and contributing to further improvements in production efficiency and quality control.

This collaboration with Defu Technology is a significant breakthrough for FASMEI cleanliness testing equipment in the new energy lithium-ion battery field, and it also confirms the adaptability of FASMEI's high-end testing equipment to core industry chains. In the future, FASMEI will continue to focus on the cleanliness testing needs of the new energy industry, driven by technological innovation, and will iterate and upgrade its products and services to provide more leading companies in the industry chain with accurate and efficient cleanliness solutions, contributing to the high-quality development of the new energy industry.
