Abstract

Nickel electrodes comprising an electrically conductive nickel sheet and a nickel layer deposited thereon which consists of spherical, porous nickel particles which adhere to each other, made by the method of partially reducing spherical nickel hydroxide particles in a reducing atmosphere at elevated temperatures to obtain partially reduced spherical Ni/NiO particles, preparing a paste from the Ni/NiO particles obtained and an organic and/or inorganic binder as well as further excipients as required, applying the paste in a layer to one or both sides of the electrically conductive nickel sheet, and tempering the coated nickel sheet in a reducing atmosphere at elevated temperatures. Self-supporting nickel layers of spherical, porous nickel particles which adhere to each other. Producing nickel electrodes and the self-supporting nickel layer, and use thereof, particularly as an electrode for water electrolysis.
