リチウムイオン二次電池用正極材料
Document Type and Number:
Japanese Patent JP7371388
Kind Code:
B2
Abstract:
To provide a positive electrode material for a lithium ion secondary battery, improved in energy density and safety without sacrificing high-speed charge/discharge characteristics.SOLUTION: A positive electrode material for a lithium ion secondary battery includes olivine-based positive electrode active material particles coated with conductive carbon which are supported on the surfaces of layered oxide-based positive electrode active material particles at a surface loading rate of 40% or more and 85% or less.SELECTED DRAWING: Figure 1
