PROBLEM TO BE SOLVED: To provide: a positive electrode for a lithium ion secondary battery, which is high in capacity and low in resistance; and a lithium ion secondary battery.SOLUTION: A positive electrode for a lithium ion secondary battery comprises: a collector; and a positive electrode active material layer bonded to the collector. The positive electrode active material layer includes: a positive electrode active material; a conductive assistant; and a binding agent. The conductive assistant includes: scale-like graphite and amorphous carbon. The content of the amorphous carbon is 1 to 5 times that of the scale-like graphite. The positive electrode active material layer has a porosity of 24-28%. |
