Lead terminal coated with an anti-corrosion coating connected with a film sealed battery or electric device

摘要

A film-sealed nonaqueous electrolyte battery comprises : a battery element including a non-aqueous electrolyte ; a film case having at least a sealant polymer resin film for sealing the battery element ; at least a lead terminal extending from the battery element and projecting from the film case, and the lead terminal with a surface having a contact area in contact directly with the sealant polymer resin film, and at least the contact area of the surface of the lead terminal is coated with an anti-corrosion coating film, wherein the anti-corrosion coating film includes : (A) a polymer of structural units of a phenolic compound, and at least a part of the structural units includes a substituent which comprises an amino group or a substituted amino group ; (B) a phosphate compound ; and (C) a titanium fluorine compound. A lead terminal connected with an electric device sealed with a film case having at least a sealant polymer resin film for sealing said electric device, and a surface of said lead terminal having a contact area in contact directly with said sealant polymer resin film, and said contact area of said surface of said lead terminal being coated with an anti-corrosion coating film as defined above.
