A method for the generation of a gas mixture including carbon monoxide, carbon dioxide and hydrogen for use in hydroformylation plants, including the steps of evaporating water to steam; feeding the steam to a solid oxide electrolysis cell (SOEC) or an SOEC stack at a sufficient temperature for the cell or cell stack to operate while effecting a partial conversion of steam to hydrogen; utilizing the effluent SOEC gas including Htogether with COfrom an external source as feed for a RWGS reactor in which the RWGS reaction takes place, converting some of the COand Hto CO and HO; removing some of or all the remaining steam from the raw product gas stream; using said gas mixture comprising CO, COand Hfor liquid phase hydroformylation utilizing carbon monoxide and hydrogen as reactants, while recycling COto the RWGS reactor.

The invention relates to a method for the precipitation of a solid material, where the method comprises: providing an aqueous metal ion solution, said metal ion solution comprising TiOSOand metal ions of a metal M, where M is one or more of the elements: Mg, Co, Cu, Ni, Mn, Fe; providing an aqueous carbonate solution; and mixing said aqueous metal ion solution and said aqueous carbonate solution thereby providing a solid material comprising titanium and a metal carbonate comprising said metal(s) M, where the titanium is homogeneously distributed within the solid material. The invention also relates to a solid material, a method of preparing a positive electrode material for a secondary battery from the solid material and the use of the solid material as a precursor for the preparation of a positive electrode material for a secondary battery.

Introduction of titanium homogeneously into a solid material

In a method for the precipitation of particles of a metal carbonate material comprising nickel and manganese in an atomic ratio of 0≤Ni:Mn≤1:3, aqueous solutions comprising sulfates or nitrates of nickel and manganese are mixed with aqueous solutions of carbonates or mixtures of carbonates and hydroxides of sodium or potassium in a stirred reactor at pH>7.5 without the use of a chelating agent. Thereby agglomerated particles are formed without any subsequent process steps, in particular no subsequent process at temperatures higher than the precipitation temperature.

Improved contact between interconnect and oxygen electrode material is achieved through a contact point between an electrode or a contact layer and a coated ferritic stainless steel interconnect, where the coating on the metallic interconnect comprises Cu.

Contact between interconnect and electrode

Improved contact between interconnect and oxygen electrode material in solid oxide cell (SOC) stacks is achieved through a contact point between the oxygen electrode or an oxygen-side contact layer of the SOC and a coated ferritic stainless steel interconnect in the SOC stack, where the coating on the metallic interconnect comprises Cu.

Contact between interconnect and cell in solid oxide cell stacks

A method for coating an interconnect for a solid oxide cell (SOC) stack comprises providing an interconnect substrate comprising Cr and Fe, coating the interconnect substrate with a first metallic layer by electrodeposition, coating the resulting structure with a second layer of metallic cobalt by electrodeposition and coating the resulting structure with a layer of metallic copper by ion-exchange plating. This way, a metallic copper-cobalt coating is formed on the interconnect.
