Abstract
Abstract A lithium secondary battery comprising an anode active material which contains at least one member selected from the group consisting of lithium, a lithium alloy, and a compound capable of intercalating and deintercalating lithium, a cathode active material, and an electrolyte which is an organic electrolyte containing a lithium salt, wherein said cathode active material is a crystalline compound obtained by mixing a lithium compound, a cobalt compound, and a vanadium compound in a molar ratio of x:y:z, respectively, wherein x is from 0 to 1.1, y is from 0.12 to 0.98, and z is 1-y, and heating the mixture.
