Title: LITHIUM ION SECONDARY BATTERY
Abstract:
This lithium ion secondary battery is provided with: a positive electrode that contains a spinel-type lithium-nickel-manganese composite oxide, which serves as a positive electrode active material, and amorphous carbon and graphite, which serve as conductive agents; and a negative electrode that contains, as a negative electrode active material, an active material where lithium ions are intercalated and deintercalated at a potential of 1.2 V or more with respect to the lithium potential.
