Claims7
A method for producing a battery with a metallic housing and an electrical insulation layer covering the outside of the housing, the method comprising:
- (i) providing a metallic housing or housing part for a battery;
- (ii) corona treating an outside of the housing or housing part with simultaneous extraction of gases arising and particles, the particles including one or more of metal particles, metal swarf, and process substances related to working of the metallic housing or housing part;
- and
- (iii) applying an electrical insulation layer to the treated outside of the housing or housing part, the electrical insulation layer consisting of a varnish.
A battery, comprising:
- a metallic housing or housing part for the battery;
- and
- an electrical insulation layer configured to cover an outside of the housing or housing part, the electrical insulation layer consisting of a varnish,
- wherein the outside of the housing or housing part is corona treated with simultaneous extraction of gases arising and particles, the particles including one or more of metal particles, metal swarf, and process substances related to working of the metallic housing or housing part.
