摘要：
A positive-electrode active material for a non-aqueous electrolyte rechargeable battery includes a core portion and a shell portion. The core portion contains an inorganic oxide with a polyanionic structure. The shell portion coats the core portion. The shell portion contains a carbon and an inorganic accelerator that accelerates generation of the shell portion by the carbon. The content of the inorganic accelerator is 0.2 mass % or more of the inorganic oxide when the mass of the inorganic oxide is defined as 100%.
