Abstract
The invention provides an electrode comprising a porous three-dimensional conductive support containing an electrochemically active material, said support having at least a first edge connected to a connection piece and at least a second edge substantially parallel to said first edge, and means for preventing said active material disposed along said second edge from moving. Said means is selected from: a piece having a U-shaped fold placed stride said second edge; a surface covering; and treatment to modify the texture of said support. The electrode is used as a positive electrode in a second electrochemical cell of the nickel metal hydride type.
