To show an LNCAO-type positive electrode active material for a lithium ion battery having a high discharge capacity per unit volume and excellent discharging capacity-holding properties. Nickel-lithium metal composite oxide powder includes a nickel-lithium metal composite oxide represented by General Formula (1) described below:LiNiMNO&#x2003;&#x2003;(1),

Nickel-lithium metal composite oxide powder and method for producing same

A process for producing a homogenous multi compound system which is hydroxide- and/or oxide-based includes a first alternative process comprising providing a first and a second refractory metal in respective hydrofluoric solutions, and mixing the first and second hydrofluoric solutions to provide a mixed hydrofluoric solution comprising a dissolved first and second refractory metal. A second alternative process comprises dissolving the first and the second refractory metal in an alternative mixed hydrofluoric solution. The mixed hydrofluoric solution or the alternative mixed hydrofluoric solution is precipitated with a precipitant to provide a solids mixture in a suspension. The first and second refractory metal is from the group consisting of Mo, W, Nb, Re, Zr, Hf, V, Sb, Si, Al, and Ta. The first and second refractory metal are different. At least one of the first and second refractory metal is provided as a fluoro and/or as an oxyfluoro complex.

Process for producing a pure-phase multisubstance system, a ceramic material based on the pure-phase multisubstance system, a shaped body, and a composite formed therefrom

Electrolyte for an electrolyte-supported high-temperature fuel cell includes zirconium(IV) oxide doped with from 3.5 mol % to 6.5 mol % of ytterbium(III) oxide. The electrolyte has a thermal expansion coefficient (TEC) based on 30&#xb0; C. of from 10.6*10Kto 11.1*10Kat 800&#xb0; C.

Electrolyte for cost-effective, electrolyte-supported high-temperature fuel cell having high performance and high mechanical strength

A process for producing anodes includes providing a foil comprising tantalum or niobium. A surface of the foil is oxidized so as to form oxides on the foil surface. The foil is heated so that the oxides formed on the foil surface diffuse into the foil. A paste comprising a powder selected from the group consisting of a tantalum powder, a niobium powder, a niobium oxide powder and mixtures thereof is applied to the foil. The foil with the applied paste is sintered.

Distortion-free screen-printed anodes on Ta/Nb sheet

A process for producing a solid electrolyte capacitor with an anode comprising a sintered fine NbOpowder, where 0.5&#x3c;x&#x3c;1.7, includes forming a green anode body. The forming is essentially performed without applying a pressure. The green anode body is sintered so as to provide a sintered anode body. The sintered anode body is electrolytically oxidized so as to provide an electrolytically oxidized anode body. The electrolytically oxidized anode body is provided with a cathode so as to provide the solid electrolyte capacitor.

Capacitor anode

The invention relates to a pulverulent zirconium oxide containing metal oxides from the group consisting of scandium, yttrium, rare earths and mixtures thereof, processes for producing them and their use in fuel cells, in particular for the production of electrolyte substrates for ceramic fuel cells.
