摘要： The invention relates to a method for preparing materials with composition gradient characteristics. After mixing a lithium source with the prepared precursor, raise the temperature from room temperature to 300° C.˜600° C. at 2° C./min˜10° C./min and maintain it, and then sinter for 5 hours˜18 hours, cool with the furnace, then raise the temperature from room temperature to 600° C.˜1200° C. at 2° C./min˜10° C./min and maintain it, and sinter for 5 hours˜18 hours, and the material is thus obtained. The material prepared with the method provided by the invention has composition gradient characteristic, and its application to the positive electrode of battery enables the battery to have higher energy density and better thermal stability, and prolonged service life.
