Unveiling a Game-Changing Copper Innovation

JinChuan Niedu Industrial Co., Ltd., a key player under JinChuan Group Co., Ltd., has unveiled a game-changing innovation: the frosted surface ultra-soft copper strip. Tailored for stamping new energy battery tabs, this upgraded product addresses a long-standing technological challenge in non-ferrous metal strip processing, filling a critical gap in China’s domestic capabilities. With mass production now underway, it’s proving to be a hot commodity in the market and a fresh driver of economic growth for the company.

Overcoming Welding Challenges with Frosted Design

Producing ultra-soft copper strips with a frosted surface has been a tough nut to crack in the industry. Smooth copper tabs, commonly used in batteries, often suffer from high reflectivity during laser welding, leading to inconsistent welds and compromised quality. JinChuan’s project team tackled this head-on through relentless experimentation, not only perfecting the frosted texture but also overcoming the fragility issues tied to cleaning and grinding such surfaces. The result is a robust, high-performance copper strip that enhances welding precision—an essential upgrade for new energy battery manufacturing.

Pushing Thickness Limits to 0.05mm

Qian Zhiguo, production manager of the High Precision Copper Strip Division at JinChuan Niedu Industrial, shared insights into the breakthrough. “After over six months of process tweaks and trial runs, we pushed beyond our equipment’s 0.08mm thickness limit to successfully mass-produce 0.05mm copper strips,” he said. This ultra-thin design meets the exacting demands of modern battery applications, ensuring JinChuan remains a frontrunner in high-precision copper technology. Now in full supply, these strips are poised to strengthen the company’s competitiveness in future bidding wars.

Aligning with Innovation-Driven Excellence

The frosted ultra-soft copper strip aligns with JinChuan Group’s broader mission—rooted in President Xi Jinping’s vision of innovation-driven development—to lead through technological excellence. By solving reflectivity and welding challenges, this product caters to the booming new energy sector, particularly electric vehicles and energy storage systems. Its success not only showcases JinChuan’s R&D prowess but also positions the company as a vital contributor to China’s push for self-sufficiency in advanced materials.

Setting a New Standard in New Energy

As demand for high-quality battery components surges, JinChuan’s latest innovation is more than a technical win—it’s a strategic leap forward. The frosted ultra-soft copper strip is setting a new standard, reinforcing JinChuan’s brand as a trailblazer in the global new energy landscape.
