Our Mission
We are devoted to empowering global technological innovation and energy
transformation through our dedication to manufacturing high-end copper-based
materials.
Our Vision
We aspire to become a world leading innovative company specializing in high-end
copper-based materials.
We are a leading global innovation-driven researcher, developer, and
manufacturer of electrolytic copper foil. According to the Frost & Sullivan
Report, we were the worldβs largest supplier of copper foil for lithium-ion
batteries, or LiB copper foil, in terms of sales volume in 2025, with a global
market share of 7.6%.
Electrolytic copper foil, also known as elecfoil, is a key intermediate
component used in manufacturing both LiB and electronic circuit boards. When
utilized in LiB cells, copper foil, as a current collector, is essential for
improving energy density as well as guaranteeing battery safety and durability,
while also helping emit heat on the anode. Copper foil used in PCB and other
electronic circuits, also known as PCB-grade copper foil, serves an important
function as a conductor for transmitting communications signals.
We primarily offer LiB copper foil and PCB-grade copper foil, and to a lesser
extent, FCCLs. In 2025, we supplied approximately 111,985 metric tons of LiB
copper foil, representing the largest global annual sales volume according to
the Frost & Sullivan Report. We have built a comprehensive product portfolio in
the global copper foil industry, consisting of copper foil products with
different specifications that meet our customersβ various and evolving needs.
Our copper foil is utilized in end markets including electric vehicles, or EVs,
energy storage systems, or ESSs, and a broad spectrum of other downstream
applications such as communication equipment and consumer electronics.
As a testament to our global leadership in the electrolytic copper foil market,
we have established a high-quality and diverse customer base over time. We serve
both domestic and international customers, and count among our customers the
worldβs top LiB and electronic circuit manufacturers such as LG Energy Solution,
Panasonic Industrial Materials, SK On, Samsung SDI, ATL, CATL, BYD, and Sunwoda,
in turn allowing our copper foil to be utilized in many industry-renowned EV,
ESS and other downstream applications. Our industry-leading customers,
especially in South Korea and Japan customers, implement a strict certification
process that creates high barriers to entry for new suppliers, with our position
as their long-term go-to supplier underpinning the superiority of our products.
For example, we have been a significant copper foil supplier to LG Energy
Solution by sales volume since 2015. We won the Level S Supplier Award by LG in
2024, the highest level honor granted to its global suppliers. As another
example, we have been supplying PCB-grade copper foil to Panasonic Industrial
Materials for 12 years, with Panasonic Industrial Materials partnering with
Nvidia to combine GPUs, networking, and storage into high-performance computing
(HPC) AI applications. In addition, according to the Frost & Sullivan Report, as
of December 31, 2025, we have the largest global customer base among all copper
foil manufacturers across a broad spectrum of downstream industries.
We believe our relationships with our key customers are commercially entrenched,
having deepened over more than a decade of strategic cooperation, equity
investments, and long-term business agreements. Over the years, we have
collaborated with customers on developing copper foil products tailored to their
specific requirements. Through leveraging in-depth, long-term cooperation, we
have developed unique insights into the latest market trends and customer
requirements for new, improved, and innovative, and most importantly, typically
higher margin copper foil products. These insights enable us to rapidly develop
differentiated products that meet downstream application requirements, often in
advance of our competitors, which in turn further enhances our customer
relationships.
Our market leadership and customers trust are built upon our robust research and
development capabilities. We invest significantly in the research and
development of copper foil manufacturing technologies. According to the Frost &
Sullivan report, our research and development expenses as a percentage of our
revenue were higher than most of our competitors globally in these periods. As
of December 31, 2025, we had a dedicated, sophisticated research and development
team comprised of 428 professionals. With over two decades of experience, we
have cultivated deep technological expertise, and currently possess the
industry-leading technological capabilities and know-how covering the major
aspects of electrolytic copper foil manufacturing, including copper dissolution,
electrolysis, surface treatment slitting, and packaging necessary to support our
research and development initiatives. According to the Frost & Sullivan report,
we were the first copper foil manufacturer in China to successfully develop 6Β΅m
high-strength LiB copper foil, and were also the first copper foil manufacturer
in the world to mass produce 6Β΅m copper foil. Additionally, we were the first
copper foil manufacturer in China to successfully develop ultra-thin LiB copper
foil with a thickness of only 4Β΅m and the first in the world to be capable of
mass producing 4Β΅m LiB copper foil with high tensile strength. Our research and
development efforts have also resulted in a robust intellectual property
portfolio consisting of 634 registered patents and 168 pending patents
applications in China as of December 31, 2025, along with a number of
confidential proprietary formulas and manufacturing techniques.
We are a pioneer in Chinaβs copper foil industry and have accumulated vast
experience in copper foil manufacturing. As of December 31, 2025, we have
approximately 728 core manufacturing personnel averaging over 10 years of
experience whose collective experience and technical expertise have strongly
contributed to our manufacturing excellence. We have continuously refined and
improved our proprietary manufacturing technologies and know-how over time,
creating a difficult to replicate competitive barrier to entry for our
competitors. With six manufacturing sites equipped with state-of-the-art
manufacturing equipment, we possess the largest global electrolytic copper foil
designed production capacity at approximately 180,500 metric tons per annum as
of December 31, 2025, according to the Frost & Sullivan Report.
