More Information
Summary:The invention relates to a method for producing copper-rich silicon foams from at least binary mixed phases, wherein a silicon layer structure is applied onto a support substrate. The aim of the invention is to provide an alternative method for using nanoparticles and nanowires which allows the production of copper-rich silicon foams that can preferably be used as a high-capacity electrode material in rechargeable batteries. This is achieved in that one layer of the silicon layer structure is made of at least two plies and at least two materials, said materials having different diffusion constants, and the layer is subjected to a rapid annealing process with a controlled energy input, wherein cavity structures with different diameters are formed.
