    摘要: To provide an active material from which a sufficient discharge capacity is obtained, an electrode containing the active material, a lithium secondary battery including the electrode, and a method for making an active material. A method for making an active material includes a temperature elevation step of heating a mixture containing a lithium source, a pentavalent vanadium source, a phosphoric acid source, water, and a reductant in a hermetically sealed container at a temperature elevation rate T1 from 25° C. to 110° C. and then at a temperature elevation rate T2 from 110° C. to a designated temperature of 200° C. or more, in which T1>T2; T1=0.5 to 10° C./min; and T2=0.1 to 2.2° C./min.
