摘要： The present invention relates to a method for producing a lithium insertion material comprising the steps of: providing an iron containing compound, a lithium containing compound and a silicate containing compound; providing a solvent; subjecting the compounds in said solvent to dissolution in order to obtain a solution; subjecting the solution to temperature above the boiling point of the solution at 1 atmosphere and at pressure above 1 atmosphere in order to obtain a precipitate; and filtering the obtained precipitate from the solution and subjecting the precipitate to washing and drying.
