Abstract
A positive electrode for a lithium secondary cell is provided that is excellent in dispersibility and adhesion of the conductive agent and provides a lithium secondary cell excellent in performance. The positive electrode for a lithium secondary cell contains a positive electrode active substance represented by the following formula (I), a conductive agent and a binder, and the conductive agent has an average particle diameter of from 3 to 20 μm measured by a laser diffraction scattering method: LixMPO4 (I) wherein M represents a metallic atom containing at least one member selected from the group consisting of Co, Ni, Fe, Mn, Cu, Mg, Zn, Ti, Al, Si, B and Mo; and 0<x<2.
