Abstract:
A method of electroconductively fastening electroconductive current collectors and metal terminals in alkali metal or alkaline earth metal batteries, and other electrochemical devices, where at least two sheets of electroconductive materials are to be electroconductively fastened together, which method comprisesselecting a base sheet or current collector from the group consisting of electroconductive fibrous materials,selecting a second sheet of electroconductive solid sheet metallic material from the group consisting of metallic sheet materials,placing said second sheet on said base sheet,placing at least one tape with an adhesive layer on said sheets with said adhesive layer facing said sheets and contacting said base sheet and said second sheet,said at least one tape being wider than at least one of said sheets,applying pressure to said assembly and activating said adhesive to cause said adhesive to flow though said fibrous material and bond with said metallic sheet material, whereby said sheets are in electroconductive contact and retained together.
