  • Publication number: 20100266905
    Abstract: A lithium secondary battery has a cathode made of carbon material capable of occluding or emitting a lithium ion, a cathode made of lithium-contained oxide, and a non-aqueous electrolyte. The non-aqueous electrolyte includes a lithium salt containing LiPF6 and LiBF4; and a non-linear carbonate-based mixed organic solvent in which (a) a cyclic carbonate having ethylene carbonate or a mixture of ethylene carbonate and propylene carbonate and (b) a propionate-based ester such as ethyl propionate are mixed at a volume ratio (a:b) in the range from about 10:90 to about 70:30. This lithium secondary battery ensures excellent high-rate charging/discharging characteristics and improved life cycle and low-temperature discharging characteristics since it includes a predetermined mixed organic solvent not including a linear carbonate. Also, since gas generation is restrained at a high temperature, a battery set may be mounted in a more improved way.

  • Publication number: 20100265297
    Abstract: An inkjet head is disclosed. In accordance with an embodiment of the present invention, the ink-jet head that prevents a nozzle from being blocked by a residual ink droplet formed on the nozzle can include a head body having the nozzle formed on one surface thereof and an actuator, which provides pressure to the inside of the head body. Here, a transfer groove is formed on one surface of the head body, in which the transfer groove is separated from the nozzle to provide a path through which the residual ink droplet moves. Thus, the inkjet head can prevent the nozzle from being blocked by a residual ink droplet formed on the nozzle by use of the transfer groove, which provides a path for a residual ink droplet formed on the nozzle to escape.

  • Patent number: 7816194
    Abstract: A method of manufacturing thin film transistor is provided, in which the method of manufacturing includes a new etching process of island semiconductor. The new etching process of island semiconductor is controlled by a flow rate of etching gas and a regulation of etching power. When etching the island semiconductor, a part of gate insulation layer exposed out of the island semiconductor is etched at the same time. Consequently, the thickness of gate insulation layer over the storage capacitance electrode is reduced, the distance between the pixel electrode and the storage capacitance electrode is decreased, and the storage capacitance of pixel is increased. Finally, the width of storage capacitance electrode is reduced appropriately and the aperture ratio of product is increased.
