  • Patent number: 9960416
    Abstract: The present invention provides a positive electrode for a non-aqueous electrolyte secondary battery in which the charge/discharge rate of a secondary battery is increased by increasing the discharge/discharge rate of the positive electrode as a result of increasing the rate of incorporation and release of lithium ions in olivine-type phosphorous complex compound particles, a non-aqueous electrolyte secondary battery provided with this positive electrode for a non-aqueous electrolyte secondary battery, and a battery module provided with this non-aqueous electrolyte secondary battery.
    Type: Grant
