(II) main business of the issuer
The company is mainly engaged in the research, production and sales of all kinds of high-performance electrolytic copper foil. Its main products are ultra-thin lithium battery copper foil, ultra-thin lithium battery copper foil and standard copper foil. It is mainly used for the manufacture of negative collector, copper clad laminate (CCL) and printed circuit board (PCB) of lithium-ion battery. It is an important basic material for lithium-ion battery industry and electronic information industry.
The company is one of the leading enterprises in China’s high-performance lithium battery copper foil industry. It has established long-term cooperative relations with well-known battery manufacturers such as Contemporary Amperex Technology Co.Limited(300750) , Ningde new energy, Byd Company Limited(002594) and has become its core supplier of lithium battery copper foil. The main function of lithium-ion battery current collector is to collect the current generated by the battery active material with metal foil in order to form a large current output. Copper foil of lithium-ion battery is not only the carrier of negative active material, but also the collection and transmission conductor of negative electrons in lithium-ion battery. Therefore, it is required to have good consistency, conductivity, flexibility and corrosion resistance.
PCB is a substrate for assembling electronic parts made by electronic printing technology. It is a printed circuit board that forms the connection between points and printed components on the general substrate according to the predetermined design. Its main function is to make various electronic parts form components and connect according to the predetermined circuit. It is the key electronic interconnection carrier of electronic products. Copper clad laminate (CCL)
It is the basic material of PCB.
