recently, Nord shares disclosed plans to invest 7.7 billion yuan to build two new energy projects, of which 2.5 billion yuan will be invested in the field of composite collector. A number of institutions said that the composite collector or will replace the traditional copper foil, mass production applications in the immediate. A number of listed companies compete to lay out the composite collection fluid business.

The current collector is a structure or part that collects current inside the lithium battery. Its functions include collecting current, distributing current, and increasing battery output power. Composite current collector is a new choice of lithium current collector, a "sandwich" structure, the outer layer is negative composite copper foil and positive composite aluminum foil, the inner layer is a polymer polymer layer (such as PP, PET, PI). The composite current collector is developing in the direction of ultra-thinning in thickness, taking into account the advantages of energy density, safety, cycle life, low cost and so on.

After the project is completed and put into production, it is estimated that 0.42 billion square meters of composite aluminum foil and composite copper foil can be produced each year, with an annual output value of about 4 billion yuan. The production line of production equipment is flexible equipment, which is compatible with the production of composite aluminum foil and composite copper foil.

In addition to Nord shares, a number of listed companies have been involved in the field of composite current collectors.

A number of listed companies to promote the composite current collector layout

Dawson shares is a veteran oil and gas equipment supplier, its holding subsidiary Hongtian Technology Co., Ltd. (hereinafter referred to as: Hongtian Technology) is a small number of domestic electrolytic copper foil equipment suppliers, electrolytic copper foil equipment market share of about 30%. Dawson shares based on electrolytic copper foil equipment, the layout of composite copper foil equipment as the company's new growth point.

in March 2023, hongtian science and technology invested in the construction of a new energy high-end equipment manufacturing project in Nantong city, Jiangsu province. the total investment of the project is planned to be 1 billion yuan. the comprehensive layout of composite copper foil integrated machines will expand the production capacity of composite copper foil and lithium battery copper foil equipment.

in April 2023, the new product vacuum magnetron sputtering all-in-one machine developed by hongtian science and technology was successfully released and won the first order, with a contract amount of about 70 million yuan, which is a major innovation and breakthrough in the company's complete set of vacuum coating equipment for composite copper foil.

in September 2023, the composite copper and aluminum foil integrated machine equipment developed by hongtian science and technology "winding magnetron sputtering coating machine" (capable of double-sided metal plating materials), "winding magnetron sputtering evaporation composite coating machine" (capable of double-sided copper plating and aluminum plating) and "winding evaporation coating machine" (capable of double-sided aluminum plating) won orders of 0.184 billion yuan from nord shares.

The main business of Sanfu Xinke (688359.SH) is the research and development, production and sales of new environmentally friendly surface engineering special chemicals and surface engineering special equipment.

in November 2022, sanfu xinke replied to the interactive reply on the certificate e. in order to provide supporting production equipment for the promotion of the company's new composite copper foil electroplating special chemicals, the company plans to add new machinery and equipment and other business scope, or will carry out research and development, production and sales of composite copper foil electroplating equipment.

in August 2023, sanfu xinke plans to issue a fixed increase to raise no more than 0.592 billion yuan, of which 0.098 billion yuan will be used to invest in the construction of a composite copper foil high-end complete equipment production center and supporting facilities, and is expected to produce no less than 10 composite copper foil equipment per year. The company's composite copper foil equipment mainly adopts a one-step all-wet process, which is outstanding in terms of coating uniformity and process automation, and can be applied to the production of composite copper foil of different substrates. The cost of the manufactured composite copper foil is about 3.8-4 yuan/m2, which is expected to fall below 3 yuan/m2 after scale-up, and the yield is expected to reach more than 95%.
