Definitions
- the present invention relates to a process for the production of conductive nickel oxide surfaces by chemical doping of the nickel oxide with alkali metal oxides, in particular for the use of the nickel in electrochemical applications.
- Another method is the several hours reduction of a complete electrode.
- nickel which is in direct contact with carbon
- the reduction not only leads to the removal of the non-conductive surface, but also to a ner relatively stable connection between the metallic nickel and the carbon material.
- a disadvantage of this method is that it is not possible, for example, the air electrode - consisting of activated carbon, manganese dioxide and nickel fabric - a fer ⁇ term zinc / air battery for several hours to reduce the hydrogen potential.
- the conductivity of the nickel is important both for the nickel / cadmium type alkaline rechargeable batteries and for the nickel / metal hydride type rechargeable battery, as described in DE 697 21 136.
- the incorporation of lithium into nickel is also known, see also DE 691 24 158.
- a low-temperature process in which an active nickel electrode is improved by treatment in a mixture of KOH, NaOH, BaOH and hydrogen peroxide.
- the treatment of an active electrode is described - not the treatment of pure, metallic surfaces.
- the object of the invention is to provide a method which makes it possible to produce conductive nickel oxide surfaces at low temperature by chemical doping of the nickel oxide with alkali oxides.
- the nickel material is immersed in a solution of 3.5 molar alkali metal hydroxide, mixed with about 10% hydrogen peroxide and stored there for 10 minutes, »the resulting nickel hydroxide surface is dewatered in a subsequent thermi ⁇ rule process
- the doped nickel oxide surfaces produced in this way are referred to below as Grenzleit ⁇ layers and have excellent conductivity.
- colloidal carbon or else hydroxides of iron, cobalt, titanium, iridium or platinum are also added during the immersion of the nickel material in the solution of 3.5 molar alkali hydroxide.
- the method includes driving the used nickel Zulegleiteren of 50 weight percent nium Alumi ⁇ or even 10 percent by weight titanium or both aluminum and titanium simultaneously.
- Example 1 shows the effect of the nickel surface on the current / voltage characteristics of Air electrodes in alkaline electrolytes on the basis of Rg. 1 and Fig. 2,
- Example 2 shows the possibilities of doping.
- Example 1 In Fig. 1 it is plotted what influence the surface of nickel precipitators on the electrochemical load capacity of air electrodes has.
- a mixture of activated carbon and carbon was prepared as a catalytically active material by a "reactive mixing process.” The mass was subsequently rolled into a metallic arrester. Nickel with a boundary layer and silver is very clearly observed, if a nickel mesh with boundary layer is used instead of the usual nickel mesh, and the performance of the air electrode is comparable to air electrodes on a silver dissipation material.
- Example 2 Nickel oxide is a known catalyst for the evolution of oxygen. Therefore, a Raney nickel catalyst is often used in electrolysis plants. Now, conditions are known in which the oxygen evolution electrode should have the smallest possible electrolytic resistance. In these cases, the catalyst used to date is a coated nickel mesh with iridium oxide.
