摘要 PROBLEM TO BE SOLVED: To provide a positive electrode for a nonaqueous electrolyte secondary battery in which the charge/discharge rate of the positive electrode is increased by increasing the lithium ion intake/discharge rate in the olivine type lithium composite compound particles, thereby increasing the charge/discharge rate of the secondary battery, and to provide a nonaqueous electrolyte secondary battery equipped with the positive electrode for a nonaqueous electrolyte secondary battery, and a battery module equipped with the nonaqueous electrolyte secondary battery.SOLUTION: The positive electrode for a nonaqueous electrolyte secondary battery contains the olivine type lithium composite compound particles having a carbonaceous coat formed on the surface as a positive electrode active material. Coating rate of the carbonaceous coat for the surface area of the olivine type lithium composite compound particles is 95% or higher, and packing density of the olivine type lithium composite compound particles in the positive electrode for a nonaqueous electrolyte secondary battery is 0.90 g/cmor more and 1.09 g/cmor less.
