The present invention relates to a method for producing Li x M y BO 3 By coating the surface of the lithium transition metal oxide particle with at least one element selected from the group consisting of M, Mn, Fe, Co, Ni, Cu and Zn and 0.9? X? 1.1 and 0.9? Y? Li 2 O-2B 2 O 3 surface It is possible to provide a secondary battery in which high voltage characteristics are improved compared to a coated cathode active material, and side reactions with an electrolyte are minimized to improve battery stability and cycle characteristics. |
