Abstract
A positive electrode for a lithium ion cell, comprising an aluminum foil, and a layer formed on the aluminum foil, wherein said layer is formed by adding 30 to 40 mass % of LiCo.sub.1-XM.sub.XO.sub.2, where M is selected from the group consisting of Ni, Fe and Al, to a spinel type of lithium manganese dioxide. Also added is a conductive agent, and a binding agent. The invention also covers a rocking chair type lithium ion cell, comprising the described positive electrode, and a negative electrode formed of a graphite-containing intercalation compound.
