Sekundärbatterie oder Zelle mit nichtwässrigem Elektrolyt

摘要

A secondary battery [2] with non-aqueous electrolyte having a high voltage and capacity and an improved cycle property, characterized in that an anode [4] is comprised of graphite spherical particles such as spherical cokes and meso carbon micro bead; a cathode [4] is comprised of composite oxides containing lithium. In a case of 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.
