  • Patent number: 5368952
    Abstract: A metal suspension half-cell for an accumulator is described, in which the metal suspension, consisting of metal particles and an electrolyte, has been stabilised by adding additive particles which comprise a ceramic material which promotes chain formation in the suspension. As a result of the said chain-forming ceramic material, the metal suspension can be operated essentially stationary within the half-cell. Diverse special geometries of the half-cell are illustrated. As a result of the composition of the suspension and the cell design, an increased cyclability of the cell is obtained. A method for operating a metal suspension half-cell according to the invention during charging/discharging thereof and a metal suspension accumulator which comprises a half-cell according to the invention are also described.

  • Patent number: 5264302
    Abstract: Described is an electrode material for use in a storage battery half-cell of the type in which a suspension of particles of active material circulates. Upon charging such a half cell the electrode material according to the invention prevents the formation of a strongly adhering precipitate of active material, such as zinc, on the electrode material. The electrode material comprises for that purpose, at least at its surface, an electrically conducting ceramic material. The invention also concerns a storage battery half-cell comprising such electrode material and a storage battery comprising one or more storage cells each comprising two of such half cells.
