Abstract
Official abstract text for this publication.
A method is disclosed for producing a battery with a metallic housing and an electrical insulation layer covering the outside of the housing. The method includes: providing a metallic housing or housing part for a battery; corona treating the outside of the housing or of the housing part, with simultaneous extraction of the gases and particles which arise; and applying the electrical insulation layer onto the treated outside of the housing or housing part.
First claim
Opening claim text (preview).
The invention claimed is: 1. 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. 2. The method as claimed in claim 1 , wherein the housing or housing part is aluminum or an aluminum alloy. 3. 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. 4. The battery as claimed in claim 3 , wherein the battery is a lithium-ion battery. 5. The method as claimed in claim 1 , wherein corona treating the outside of the housing or housing part increases a surface tension of the outside. 6. The method as claimed in claim 1 , wherein corona treating the outside of the housing or housing part brings a surface tension of the outside to a uniform level. 7. The method as claimed in claim 1 , wherein corona treating the outside of the housing or housing part increases a surface tension of the outside by 21%.
