R&D and Manufacturing

R&D technologies

International research team: led by senior industry experts from China, Japan and South Korea, and consisting of domestic high-end young talents engaged in electrochemistry, materials science, and mechanics.

Technological monopoly broken for many times, and continuous iteration of high-performance products：
The 6μm high-strength lithium copper foil products have been successfully developed and the earliest batch to the market, a number of technologies to fill the domestic gap, the overall technology has reached the international advanced level；
The 6μm super strong lithium copper foil product development success；
The 5μm high modulus copper foil first developed successfully；
The 4.5μm lithium copper foil products are supplied to BYD, China Innovation Singapore Airlines and other leading lithium enterprises in batches, and the performance indicators of the products have reached the world's leading level；
The 4μm series 330-400MPa medium strength, 400-500MPa high-strength, and 500MPa or above ultrahigh-strength whole series high-grade copper foils have been mass produced, breaking the monopoly of Japanese and Korean enterprises in the copper foils for very thin lithium batteries；
The HVLP (5G) copper foil has been first successfully developed and mass produced in China.

Continuous increase of investment in scientific research, and abundant results: With the highest R&D cost in the industry, i.e. over 3%, the company has been totally awarded with 620 utility model patents and 45 patents for invention, and has published 65 scientific papers and transformed 35 achievements.

Production process

With over 20 years of experience in copper foil manufacturing, the proportion of personnel with more than 20 years of experience in this field exceeds 40%. The product's craftsmanship, technology, and quality have become an industry benchmark. We forge brand advantages based on technological strengths, and our products are sold well overseas.

Worldwide first-class equipment and production technologies: Advanced equipment imported from abroad is adopted mainly, together with the international advanced low-temperature copper melting technology, whole-process online monitoring equipment, production equipment at a high degree of automation, and a large number of green energy and advanced energy distribution systems.

Quality assurance system
