  • SECONDARY BATTERY AND CYLINDRICAL LITHIUM SECONDARY BATTERY
    Publication number: 20170373339
    Abstract: A secondary battery or a cylindrical lithium secondary battery is generally described. An exemplary lithium secondary battery module includes: an electrode assembly; a first current collector plate; and a second current collector plate. The electrode assembly is formed by winding an anode plate having a first uncoated region formed on one side, a cathode plate having a second uncoated region formed on the other side, and a separator disposed between the anode plate and the cathode plate. The first current collector plate is electrically connected to the first uncoated region through direct contact therewith, and the second current collector plate is electrically connected to the second uncoated region through direct contact therewith. The second uncoated region of the cathode plate and the first uncoated region of the anode plate are formed of the same metal material.
