Composite copper foil - the trend of the new era

Composite copper foil - the trend of the new era

Copper foil, as the negative electrode collector of lithium batteries, mainly plays the role of carrying negative electrode active materials and collecting current. Traditional copper foil uses 99% high-purity electrolytic copper as the main material, which has the advantages of strong conductivity, good heat dissipation, and low manufacturing cost. However, there are also problems such as high mass ratio and high raw material cost. There are mainly two points:

What is copper foil tape and what is it used for?

Copper foil tape is a kind of metal tape. It is mainly used in electromagnetic shielding. It is divided into two types: electrical signal shielding and magnetic signal shielding. Electrical signal shielding mainly relies on the excellent electrical conductivity of copper itself, while magnetic shielding requires copper foil tape. Surface conductive material "Nickel" is used to achieve the effect of magnetic shielding, so it is widely used in mobile phones, notebook computers and other digital products.

Copper foil production and the role of rubber rollers

Copper foil production and the role of rubber rollers

The production process of lithium battery copper foil consists of a copper melting process, an electrolytic foil production process, a surface treatment process, and a cutting and testing process. In order to better understand the application of ultra-thin copper foil for lithium batteries and electronics, we briefly introduce its production process.

Jiangxi launched the "Project Conference War" in an all-round way, and the start of many places is like a rainbow

On February 6, Jiangxi held the coordinated start of three major projects at the provincial, city and county levels and the 2023 "Project Battle" mobilization meeting. On the same day, many counties and districts in the province also followed suit and held major project start activities in the first quarter. What did the local officials say at the event? What actions will you take after the meeting?
