Abstract
An electrode for a lithium-ion battery. The electrode has at least one porous silicon layer and a copper layer. There is also described a battery with such an electrode, a method for producing an electrode of this kind, and the use of an electrode of this kind in a battery.
Claims18
A process for producing an electrode having at least one porous silicon layer and a copper layer on the at least one porous silicon layer, the process comprising:
- etching a silicon substrate for forming at least one porous silicon layer;
- and
- depositing a copper layer on the at least one porous silicon layer;
- wherein the electrode is configured for a lithium-ion battery;
- and
- etching the silicon substrate to form a multilayer system made up of a plurality of porous silicon layers that differ from one another in a quality of the porous silicon layers selected from the group consisting of porosities, pore sizes, and pore shapes, and wherein the at least one porous silicon layer is one of the plurality of porous silicon layers of the multilayer system.

An electrode having at least one porous silicon layer and a copper layer on the at least one porous silicon layer, comprising:
- an etched silicon substrate forming at least one porous silicon layer;
- a copper layer deposited on the at least one porous silicon layer;
- the electrode being configured for a lithium-ion battery;
- and
- a plurality of porous silicon layers forming a multilayer system arranged on top of one another and differing from one another in a quality selected from the group consisting of porosities, pore sizes, and pore shapes, and wherein said at least one porous silicon layer is one of said plurality of porous silicon layers of said multilayer system.
