Abstract

1383957 Hot-pressing powder mixtures CENTRE NATIONAL D'ETUDES SPATIALES 23 March 1972 [30 June 1971] 13757/72 Heading C7D [Also in Division H1] A method of making an electrode comprises the steps of preparing a powder mixture of a powdery compound forming the electro-chemically active material of the electrode or capable of forming it by chemical or electro-chemical reaction, and of a metal powder forming the conductive support material of the electrode, and hot pressing the powder mixture in an atmosphere to which the mixture is inert, to produce an electrode of the desired shape by sintering the conductive support material without chemical transformation or volatilization of the powdery compound. The material comprising the powdery compound is chosen to have a melting point and temperature of decomposition well above the sintering temperature of the metal powder forming the conductive support material. Depending on the materials constituting the powder mixture the sintering is carried out over a range between 300 and 700‹C at a pressure between 100 and 2000 Kg/cm<SP>2</SP>. Examples of powder mixtures are as follows, the first powder constituting the support and the second powder constituting the active material:- (i) nickel, nickel fluoride, (ii) as (i) but with small proportion of cobalt fluoride, (iii) nickel, cadmium fluoride, (iv) as (iii) but with small proportion of Fe 2 O 3 , (v) and (iii) but cadmium fluoride replaced by KCdF 3 , (vi) Ag, KCdF 3 with small proportion of TiO 2 , (vii) Ag, Ag 2 SO 4 , (viii) Zn, ZnO, with small proportion of mercury oxide and ammonium chloride, (ix) as (viii) but ZnO replaced by Zn 3 (PO 4 ) 2 , (x) Cu, CuF 2 , (xi) Ag, HgO. The sintered electrode, for example, as in (i) may then be immersed in 6N-KOH and the NiF 2 converted to Ni(OH) 2 . The electrode is then formed by a series of charging and discharging cycles in an alkaline electrolyte to produce NiOOH. A bi-polar electrode is described having one side as (iv) and the other side as (ii). A metal grid may be incorporated in the powder mixture before the sintering step and a plastics binder may also be incorporated to avoid the use of a mould, and in this instance the mixture may be dissolved in a volatile solvent and applied by a spray gun to the grid. Examples (x) and (xi) are intended for use as cathodes in primary cells and the subsequent chemical treatment is omitted.
