Abstract
Official abstract text for this publication.
An electrode for lithium ion batteries, the electrode having a metal film which is inert to lithium ions and having a plurality of silicon nanowires protruding from the film, which are arranged on at least one flat side of the film, wherein sections of the nanowires are enclosed by the metal film.
First claim
Opening claim text (preview).
1 . A method for manufacturing an electrode for lithium on batteries, comprising the following steps: (a) electrochemical etching a silicon wafer to form pores up to a predetermined pore depth P in a preselected arrangement; (b) converting the pore wags, by overetching the pores, into upright nanowires attached to the wafer which have a predetermined thickness; and (c) forming a film of a predetermined thickness D from a metal which is inert to lithium ions, by electrodeposition on the etched side of the wafer, wherein the metal film encloses the attached ends of the nanowires, and the nanowires protrude by a length of about P-D from the flat side which is opposite to the wafer. 2 . The method according to claim 1 , wherein the metal film is detached from the wafer while the nanowires are torn off at the same time. 3 . The method according to claim 2 , wherein the wafer including the metal film arranged thereon is heated, and the metal film detaches from the wafer due to its thermal expansion.
