Sodium-nickel battery positive electrode material and preparation method thereof

The invention relates to a positive electrode material for a sodium-nickel battery. The positive electrode material is composed of nickel powder, sodium chloride and trace elements, wherein the mass ratio of the nickel powder to the sodium chloride to the trace elements is x:y:(1-x-y), x is equal to 0.4-0.6, y is equal to 0.4-0.6, and (1-x-y) is equal to 0-0.2. The invention further discloses a preparation method of the positive electrode material for the sodium-nickel battery. The positive electrode material provided by the invention has relatively good conductivity and relatively high tap density. 本发明涉及本发明提供了一种钠镍电池用正极材料由镍粉、氯化钠、微量元素组成，镍粉、氯化钠、微量元素质量比为x：y：1-x-y；其中x＝0.4～0.6，y＝0.4～0.6，1-x-y＝0～0.2.本发明还保护了一种钠镍电池正极材料的制备方法。本发明的正极材料具有较好的导电性及较高的振实密度。
