    摘要： Provided are a method of manufacturing a cathode active material for a lithium battery, and a cathode active material obtained by the method. The method includes forming a precursor of a one-dimensional nanocluster manganese dioxide with a chestnut-type morphology, inserting lithium into the formed precursor and synthesizing a one-dimensional nanocluster cathode active material particle with a chestnut morphology, coating a water-soluble polymer on a surface of the cathode active material particle, adsorbing a metal ion to the surface of the cathode active material particle coated with the water-soluble polymer, and sintering the cathode active material particle to obtain the one-dimensional nanocluster cathode active material with a chestnut morphology. The cathode active material manufactured by the above method is a one-dimensional nanocluster with a chestnut-type morphology, which has a uniform-thick metal oxide layer on its surface, thereby ensuring an improved capacity of the cathode active material and an excellent cycle characteristic.
