  • Method of joining a metal connection tab to an electro-chemical cell electrode having a foam-type support, and an electrode obtained by the method
    Patent number: 5456813
    Abstract: A metal connection tab is joined to an electrochemical cell structure having a foam-type support. The support is formed with a porosity of greater than 90%. Thereafter the support is filled with active material. A connection tab is formed of expanded metal or of perforated metal foil having perforations occupying more than 40% of its surface area, and is formed to include two branches that are fixed to each other and that are disposed on opposite sides of the support previously filled with active material. The branches are compressed against opposite sides of the support such that the three-dimensional porous structure of the support and the connection tab are caused to interpenetrate and bind together.
