摘要： The present invention relates to a cathode active material for lithium secondary battery, which is a lithium transition metal oxide of a-NaFeO2 layered crystal structure, wherein the transition metal includes mixed transition metals of Ni and Mn. The cathode active material satisfies the conditions that the average oxidation number of total transition metals except for lithium is greater than +3, and m(Ni) = m(Mn), wherein m(Ni) and m(Mn) stand for mole of manganese and nickel respectively. Contrary to the prior art, the cathode active material adjusts the oxidation state of transition metals to greater than +3, and thus forms a more uniform and stable layered structure, wherein the transition metals are in the transition metal oxide layer and form layered structure. Accordingly, the overall electrochemical properties including the battery capacity can be improved and especially, the high charge and discharge rate property is excellent.

摘要： The present invention provides a lithium iron phosphate in which an olivine crystal structure is formed and carbon(C) is coated on a particle surface of the lithium iron phosphate, wherein when powder of said lithium iron phosphate has been dispersed in water for one hour and then a quantitative analysis has been performed for the lithium iron phosphate residual from which water was removed from a dispersed liquid, a weight ratio of a lithium iron phosphate generated after carbon has been peeled off was less than or equal to 0.005 wt% compared with the total weight of the lithium iron phosphate coated with the carbon. Since said lithium iron phosphate is coated with the carbon on the particle surface with a very small amount that leaches water, the invention is hardly separated during an electrode manufacturing step due to a uniform thin film coating effect on the particle surface of the lithium ion phosphate, and has excellent conductivity and superior density.
