Abstract:
1. A method of manufacturing a nonaqueous electrolytic secondary battery including a positive electrode active material capable of intercalating and deintercalating a lithium ion, a negative electrode active material capable of intercalating and deintercalating the lithium ion, and a nonaqueous electrolyte, comprising the steps of: mixing a first component having a lithium compound, a second component having a cobalt compound, and a third component having a halogen compound to obtain a 3-component mixture; and burning the 3-component mixture to obtain a hexagonal system lithium containing cobalt composite having a crystallite size in a (110) vector direction of 1000Å or more, wherein the cobalt compound is a tricobalt-tetraoxide (Co
