Abstract
A method for production of an electrode for a battery cell of an electrical energy storage device by a generator includes spraying an electrode powder onto a metallic substrate web by a spraying device of the generator and compressing the electrode powder onto the metallic substrate web by a stamping device of the generator. Before the spraying, the electrode powder is electrically charged by corona or tribological charging.
Claims5
A method for production of an electrode (12) for a battery cell of an electrical energy storage device by a generator (10), comprising the steps of:
- spraying an electrode powder (18) received from a reservoir (30) onto a metallic substrate web (20) by a spraying device (14) of the generator (10);
- compressing the electrode powder (18) onto the metallic substrate web (20) by a stamping device (16) of the generator (10);
- before the spraying, electrically charging the electrode powder (18) by corona or tribological charging;
- removing uncompressed electrode powder (18) from the metallic substrate web (20) after the compressing by an air jet (28);
- and
- feeding the uncompressed electrode powder (18) after the removing into the reservoir (30).
