POSITIVE ELECTRODE FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY AND BATTERY MODULE |
摘要 |
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. The positive electrode for a non-aqueous electrolyte secondary battery of the present invention is a positive electrode for a non-aqueous electrolyte secondary battery containing olivine-type lithium complex compound particles having a carbonaceous film formed on the surface thereof as a positive electrode active material, in which the coverage factor of the carbonaceous film relative to the surface area of the olivine-type lithium complex compound particles is preferably 95% or more, and the packed density of the olivine-type lithium complex compound particles in this positive electrode for a non-aqueous electrolyte secondary battery is preferably 0.90 g/cm 3 to 1.09 g/cm 3 . |
