Abstract: Provided is a method for welding an electrode assembly comprising stacking a plurality of electrodes to manufacture the electrode assembly, attaching a buffer tab to a surface of an outermost electrode tab of the electrode assembly, and welding a lead such that a plurality of electrode tabs and the lead are in contact with each other to dispose the buffer tab therebetween. The electrode assembly comprises the stacked plurality of electrodes comprising the lead welded to the plurality of electrode tabs, and each electrode tab of the plurality of electrode tabs protrudes in one direction from the plurality of electrodes. The buffer tab may be attached, before the welding, to the surface of the outermost electrode tab to minimize or prevent damage to the electrode tab due to pressure applied by a welding rod.

Abstract: The present invention relates to a skin care system and methods for providing the same, and comprises; a server including databases and a transceiver unit; a portable terminal connected wirely or wirelessly to the server, and including an application for providing skin care services; a skin care apparatus connected wirely or wirelessly to the portable terminal; and the skin care apparatus operates according to a control signal of the portable terminal, wherein the control signal is generated based on the database according to cosmetics and a user's condition provided from the server.

Abstract: Disclosed is a skin care appliance capable of realizing various skin care modes using an oscillator vibrating up and down in the way of a magnetic coil, conducting the galvanic massage and the iontophoresis massage based on the oscillator, and making the magnetic-color-sound therapy. The skin care appliance includes a case with a predetermined shape, and a vibration unit installed within the case and having an oscillator. The oscillator oscillates in the way of a magnetic coil upon receipt of the power from a power supply unit. An outer electrode is charged to a polarity opposite to the polarity of the oscillator, and placed at the case. A switch unit is provided at the case. A control unit controls the vibration unit in accordance with the signals from the switch unit.
