<P>PROBLEM TO BE SOLVED: To provide a non-aqueous electrolyte secondary battery in which the high temperature characteristics can be improved without degrading the battery capacity, and its manufacturing method. <P>SOLUTION: This non-aqueous electrolyte secondary battery comprises a positive electrode made mainly of a positive active material, a negative electrode, and a non-aqueous electrolyte. The positive active material is a hexagonal system lithium-containing transitional metal compound oxide containing a compound as expressed by a general formula LiCo<SB>1-x</SB>M<SB>x</SB>O<SB>2</SB>(where, M is at least one kind selected from among the group of V, Cr, Fe, Mn, Ni, Al, and Ti), magnesium and halogen. <P>COPYRIGHT: (C)2003,JPO |
