Abstract
A secondary battery with non-aqueous electrolyte having a high voltage and energy density and a superior cycle property, characterized in that a cathode comprises composite oxides containing lithium and an anode comprises composite carbon materials containing graphite spherical particles and carbon fibers. The carbon fiber improves the stiffness of the anode depolarizing mix to prevent the body made thereof from swelling and decomposing.
