PURPOSE: A pantograph, an electrode, and a secondary battery using the electrode is provided to improve the energy density of a battery by using a pantograph with penetrating holes according to a predetermined pattern. CONSTITUTION: A pantograph, an electrode, and a secondary battery using the electrode comprise an electrode plate, an electrode assembly(100), a case(140), and a tap(101,102). The electrode plate is formed with a pantograph and an electrode active material. The electrode active material is adhered to the pantograph. The electrode assembly is formed with the electrode plate and a separator. The case covers the electrode assembly. The tap is connected with a terminal of the electrode assembly and it is projected to an outside of the case. |
