Abstract
The object of the present invention is to provide a method for producing simply a positive electrode active material which can further increase charge-discharge capacity of secondary batteries when the positive electrode active material is used for positive electrode of secondary batteries, particularly non-aqueous electrolyte secondary batteries. A method for producing a positive electrode active material includes the step of heat-treating a lithium mixed metal oxide represented by the formula Li2MO3 in the presence of a hydride wherein M is at least one element selected from the group consisting of Ti, V, Mn, Fe, Co and Ni.
