Title:
Quality for rechargeable batteries of cathode active material, and a manufacturing method for the same
Document Type and Number:
Japanese Patent JP6042511
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a positive electrode active material for a secondary battery, which enables the effective reduction in water content while imparting the property less likely to absorb a water content to a positive electrode active material per se, and a method for manufacturing such a positive electrode active material in order to offer a high-performance lithium ion secondary battery or sodium ion secondary battery.SOLUTION: A positive electrode active material for a secondary battery comprises a composite including at least an oxide including iron or manganese, and expressed by one of the formulas (A) to (C) below, and a cellulose nanofiber-originating carbon, and graphite supported by the composite: LiFeMnMPO(A); LiFeMnNSiO(B); and NaFeMnQPO(C).SELECTED DRAWING: None
