    摘要: The present invention relates a microporous polyethylene film with improved mechanical strength, porosity, pore size and, particularly, improved surface energy, thereby having improved electrolyte wettability and being adequate for use as separators in high-capacity and long lifetime lithium secondary batteries. The microporous polyethylene film of the present invention is characterized by having a surface energy of at least 50 dynes/cm 2 , an air permeability (Darcy's permeability constant) of at least 2.0x10 -5 , a puncture strength of at least 0.17 N/m, a product of the air permeability and the puncture strength of at least 0.34x10 -5 Darcy N/m, a weighted average pore size of at least 30 nm, and a film shrinkage in the transverse and machine directions of not more than 5% at 105 °C for 10 minutes and not more than 15% at 120 °C for 60 minutes, respectively. The microporous polyethylene film is prepared by compounding raw materials in an extruder such that a thermodynamic single phase is formed above the temperature of liquid-liquid phase separation, inducing sufficient phase separation in a phase separation zone formed inside the extruder by controlling the temperature below the temperature of liquid-liquid phase separation, forming through a die, and carrying out plasma treatment in order to enhance surface energy.

    摘要: A lithium secondary battery includes an electrode assembly having at least one tab which projects from one side of the electrode assembly, an external finishing material surrounding and sealing the tab except a distal end portion thereof and the electrode assembly, and polymer films interposed between the external finishing material and the tab to improve adhesion therebetween. When the tab has a thickness no less than a predetermined thickness, the tab is formed to have a sectional shape which ensures that an inside angle defined by one of upper and lower surfaces of the tab and an adjacent side surface of the tab becomes an obtuse angle, and the polymer films are formed to have protuberances on the inner surfaces thereof, so as to improve bondability between the tab and the polymer films.

    摘要: Disclosed herein is a structure of layering unit cells for a lithium polymer battery, in which electrode terminals are provided on surfaces of the respective unit cells for the lithium polymer battery, and are alternately layered, thus allowing the unit cells to be connected in series through only a layering operation without an additional connecting device. The battery system includes first and second unit cells each having a pouch and anode and cathode terminals which are connected to a surface of the pouch and are oppositely bent in upward and downward directions. In this case, the cathode terminal of the second unit cell is directly connected to the anode terminal of the first unit cell.
