Battery connector protection

摘要

Internal intercell and terminal cell electrical connector elements in an electrochemical battery are protected from corrosion and build-up of high internal resistance by coating the electrical connector elements with a layer of a protective preferably non-conductive viscous material such as silicone, prior to pressure contacting or welding of the electrical connector elements. The silicone is removed only at the point of contact between the connector elements while retaining a surrounding protective barrier against the corrosive effects of the cell components and particularly corrosive fluid organic electrolyte materials in high energy density cells.
