Title: SECONDARY BATTERY POSITIVE ELECTRODE ACTIVE MATERIAL AND METHOD FOR PRODUCING SAME
Abstract:
In order to obtain a high-performance lithium-ion secondary battery or sodium-ion secondary battery, the present invention provides a secondary battery positive electrode active material capable of effectively suppressing water absorption, and a method for producing the same. To be specific, the present invention pertains to a secondary battery positive electrode active material in which a water-insoluble conductive carbon material and a carbon obtained by carbonizing a water-soluble carbon material are supported on an oxide containing at least iron or manganese and represented by formula (A) LiFeaMnbMcPO4, formula (B) Li2FedMneNfSiO4, or formula (C) NaFegMnhQiPO4.
