Abstract

A lithium secondary battery comprising a positive electrode composed of a positive electrode active material comprising at least one member selected from the group consisting of lithium phosphate, lithium-cobalt phosphate, cobalt oxide, and lithium-cobalt oxide, such that the molar ratio of cobalt:phosphorus:lithium is more than 0.1: more than 0.2:1, a negative electrode, and an electrolyte. The lithium secondary battery of the invention has high energy density leading to high discharge capacity, high electromotive force, and high discharge voltage, and excellent cycle properties.
