To provide an anode material for a lithium secondary battery having high discharge capacity, excellent cycle characteristic and high charge discharge efficiency, to provide a method for manufacturing the anode material, and to provide a lithium secondary battery including the material.
A positive active material for the lithium secondary battery is composed of a lithium manganese phosphate based compound including one metal element selected among Mg, Ti, Ni, Co, and Fe and having phosphorus a part of which is substituted with arsenic. The positive active material is manufactured by reacting a lithium oxide, a manganese oxide, a phosphorus oxide, a chelate agent, and water in a hydrothermal reactor, and adding a substitution product of the above elements and arsenic substitution to react together.
