Abstract
An electrode component for an electrochemical cell or a capacitor is described wherein the electrode is produced by physical vapor depositing an electrode active material onto a substrate to coat the substrate. The thusly produced electrode is useful as a cathode in a primary electrochemical cell and as a cathode and an anode in a secondary cell, and as an electrode in an electrochemical capacitor and an electrolytic capacitor.

A method for manufacturing a cathode of an electrochemical cell, comprising the steps of:
- a) providing a substrate;
- b) roughening at least a contact surf ace of the substrate;
- and
- c) physical vapor depositing a cathode active material onto the contact surface of the substrate to provide the cathode.
A method for manufacturing an electrochemical cell, comprising the steps of:
- a) providing a casing of an electrically conductive material;
- b) providing an anode disposed inside the casing;
- c) providing a cathode current collector;
- d) roughening at least a contact surface of the cathode current collector;
- e) physical vapor depositing a coating of cathode active material onto the contact surface of the cathode current collector to provide a cathode;
- f) positioning the cathode and the anode inside the casing;
- and
- g) activating the anode and the cathode with an tonically conductive electrolyte filled in the casing.
