POSITIVE ELECTRODE FOR LITHIUM SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a positive electrode, which does not prevent diffusion of a lithium ion and has low electrical resistance. SOLUTION: A positive electrode for a lithium secondary battery comprises a positive active material 1, a conductive body and a bonding agent. The conductive body is structured having both spherical graphite 2 and fibrous carbon 3 as main ingredient. A surface of the positive active material 1 is covered mainly by the spherical graphite 2 so that electrical resistance on the surface thereof is reduced. A conductive pass among the positive active material 1 is provided mainly by the fibrous carbon 3 so that resistivity of the positive electrode is reduced.
