摘要：
The present invention provides a positive electrode active material that has rate characteristics suitable for nonaqueous electrolyte batteries and particularly nonaqueous electrolyte secondary batteries, a method by which this positive electrode active material can be easily mass produced, and a high-performance nonaqueous electrolyte battery that has a positive electrode active material obtained by this method.The present invention relates to a method of producing a positive electrode active material, the method comprising a step of mixing a carbon source with lithium manganese phosphate LiMnPO4 or a compound LiMn1-xMxPO4 (where, 0≦x
