摘要： The present disclosure provides a method for preparing full-gradient particle precursors, and the full-gradient particle precursor prepared thereby. By controlling different types of anion compositions and/or cation compositions gradually changed to other types, and adjusting the pH to match with the species, precipitated particles are deposited to form a slurry, collecting the precipitated particle, treating with water, and drying to yield the particle precursor. After being washed and dried, the particle precursor is further mixed with lithium source, after calcining to yield cathode active particles. The cathode active particles can be used to prepare cathode of lithium-ion battery.
