Copper foil is an indispensable basic material for 5G base station construction. Because of its good conductivity, it is mainly used in the construction of lithium batteries.
Copper foil has a very high status in the field of electronic products. Products made of copper foil are widely used in the field of electronic information.
Copper foil includes electronic circuit copper foil, used for copper clad laminates, printed circuit boards; lithium battery copper foil, mainly used for power, consumer, and energy storage lithium batteries. The increase in demand for lithium battery copper foil is mainly driven by power lithium batteries .
5G base stations have very high requirements for the same period of the previous year, but the proportion of high-performance copper foil in China is still low, and the high-end market is still occupied by Japanese and European copper foil manufacturers.
As one of the earliest companies in the industry to deploy high-frequency high-speed lithium battery copper foil, GDCH Copper Foil Technology Group said that it has successfully developed RTF copper foil that can be used for 5G communication by users, and has completed bulk shipments, and will continue to promote copper foil for HDI The development progress of high-end products such as high-end products further enriches the products in the field of high-end electronic circuit copper foil.
GDCH already has the mass production capacity of 6μm lithium battery copper foil, the main products are: very thin lithium battery copper foil, high-end HDI copper foil, VLP copper foil, HVLP copper foil, high tensile lithium battery copper foil, RTF copper foil, high frequency and high speed CCL currently has an annual capacity of 12,000 tons of copper foil, an annual capacity of 12 million copper clad laminates, and an annual production capacity of 7.4 million square meters of PCBs. The high-precision electronic copper foil project to be put into production (Phase II) will increase the annual production capacity of copper foil by 8,000 tons, half of which will be the production capacity of lithium battery copper foil for new energy vehicles.
In addition, the company plans to build an electronic information industry base in Meixian District in the early stage, and plans to build a 20,000-ton high-precision electronic copper foil project in the first stage, which is being promoted quickly and orderly.
NDTB Copper Foil Technology Group is the first domestic enterprise that independently develops and produces copper foil materials. It owns three large-scale copper foil material production plants. Its main products are self-developed 4-6μm copper foil, porous copper foil, and ultra-thick copper foil, which have obvious technical and cost advantages in the market.
A few days ago, NDTB announced the establishment of a long-term cooperative relationship with LG Chem to become the core supplier of the latter's lithium battery copper foil. Last month, NORD planned to raise no more than 1.42 billion yuan, mainly with the investment in an annual output of 15,000 tons of high-performance ultra-thin lithium battery copper foil project. After completion, the total production capacity will reach 43,000 tons.
AHTG Copper Foil Technology Group aims at the development of 5G communications, researching high-frequency high-speed electronic copper foil products. At present, it has an annual production capacity of 45,000 tons of high-performance, high-precision electronic copper foil, ranking first in China and fourth in the world.
The company's 5G universal copper foil has been at the forefront of the country, RTF copper foil has achieved mass production, and the supply has reached 300 tons/month, and the supply will increase to 500 tons/month at the end of the year.
At present, the lithium battery copper foil market is dominated by 8μm. However, the thinner copper foil means less resistance, and the corresponding weight is also lighter. The battery energy density and other properties will also be improved, and the cost of copper foil raw materials will be effectively reduced. The use of thinner and thinner copper foils for lithium batteries is the general trend in the future.
