Summary:A method for producing a lithium nickel metal oxide material and a particulate lithium nickel metal oxide material having a defined crystallite size are provided. Such materials can be used as cathode materials for secondary lithium ion batteries. The method comprises: a first calcination step comprising heating at a temperature of between about 460 DEG C and about 540 DEG C for a period of between 3 hours and 10 hours; and a subsequent second calcination step comprising heating to a temperature above about 600 DEG C for a period of time between 30 minutes and 4 hours. 提供一种用于产生锂镍金属氧化物材料的方法以及一种具有限定微晶尺寸的粒状锂镍金属氧化物材料。此类材料可用作二次锂离子电池的阴极材料。所述方法包括：第一煅烧步骤，所述第一煅烧步骤包括在约460℃至约540℃之间的温度下加热3小时至10小时之间的时段；以及后续第二煅烧步骤，所述第二煅烧步骤包括加热至高于约600℃的温度，持续30分钟至4小时之间的时段。
