Application of micron copper foam in batteries

The special three-dimensional structure of copper foam makes it have many excellent properties that are different from traditional materials. It is these properties that make it very suitable for the design of new battery current collectors:

High porosity: The porosity of copper foam can reach more than 98%, and it has an almost fully transparent structure, so it is easier to combine with other materials to play a special role and improve battery performance;

Large specific surface area: under the same porosity, compared with other porous materials, it has the largest specific surface area, up to more than one square meter per gram;

High porosity and uniform pore structure: The porosity of copper foam is as high as 95% or more, which is a three-dimensional porous and permeable structure with good metal strength. Under the same volume, the weight of the material will be lighter, and at the same time, it can accommodate the highest, which can play a very good sound absorption, energy absorption, and electromagnetic shielding performance;

Metal properties: Copper foam retains the metal properties of copper, so it can be fireproof, non-toxic, non-dropping residue, recyclable, thermally conductive, etc. to a certain extent, not only has a wide range of applications, but also can be recycled as a metal material Significant cost savings while responding to low-carbon environmental initiatives.
