| Abstract | (54) CATHODE MATERIAL USABLE FOR Publication Classification BATTERIES AND METHOD OF MAKING SAME (51) Int. Cl. HOLM 4/58 (2010.01) (75) Inventor: Jen-Chin HUANG, New Taipei City COB 25/26 (2006.01) (TW) (52) U.S. Cl. USPC ........................................ 252/182.1; 423/306 (73) Assignees: GOLDEN CROWN NEW ENERGY (HK) LIMITED, Kowloon (HK); (57) ABSTRACT SUZHOU GOLDEN CROWN NEW A method for preparing a cathode material. In one aspect, the ENERGY CO.,LTD., CHANGSHU method includes: (1) providing a mixture of at least one CITY (CN) iron-containing compound, at least one lithium-containing compound, at least one phosphorus-comprising compound, and at least one oxygen-containing compound, and (2) sin (21) Appl. No.: 13/361,519 tering the mixture, in which the decomposition temperature of the iron-containing compound and the lithium-containing compound is lower than that of the phosphorus-comprising (22) Filed: Jan. 30, 2012 compound and/or the oxygen-containing compound. The cathode material thus prepared, for example, a LiFePO pow (30) Foreign Application Priority Data der, has a purity ranging from about 90% to about 95% by weight, and a gram specific capacity ranging from about 150 Dec. 2, 2011 (CN) ......................... 2O1110395.156.O to about 170 mAh/g. |
