Abstract
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.
