Zusammenfassung:There is provided a particle for use as a precursor material for the synthesis of a lithium ion cathode active material for a lithium ion battery, comprising: a non-lithiated nickel oxide particle of formula MOx wherein M comprises 80 at% or more Ni, and wherein x is 0.7 to 1.2, M optionally not comprising boron in the MOx crystal structure; and a modifier oxide intermixed with the non-lithiated nickel oxide particles, coated on the non-lithiated nickel oxide particles, present within the non-lithiated nickel oxide particles, or a combination thereof, where the modifier oxide is associated with the non-lithiated nickel oxide such that calcination at 500 DEG C for 2 hours results in microcrystalline growth of 2 nanometers or less as measured by XRD. Methods of forming electrochemically active particles using the precursor nickel oxide are also provided. 提供了用作用于合成锂离子电池的锂离子阴极活性材料的前体材料的粒子,其包含:式MOx的非锂化镍氧化物粒子,其中M包含80原子%或更多的Ni,并且其中x为0.7至1.2,M任选在MOx晶体结构中不包括硼;和与非锂化镍氧化物粒子互混、涂布在非锂化镍氧化物粒子上、存在于非锂化镍氧化物粒子内或其组合的改性剂氧化物,其中所述改性
