Zusammenfassung:A positive electrode for lithium ion secondary batteries includes a collector and a positive electrode active material layer formed on at least one surface of the collector. The positive electrode active material layer contains a lithium-containing metal oxide having a unit cell represented by the following formula and a conductive material and has voids with a volume of 0.82×10−3 cm3/cm2 to 7.87×10−3 cm3/cm2 per unit area of the collector: LiFe1-xZrxP1-ySiyO4  (1) where 0
