20110300418Lithium secondary battery - A lithium secondary battery including lithium molybdate. The lithium molybdate is a composite including amorphous lithium molybdate as a minor component and crystalline lithium molybdate as a major component.12-08-2011
20120003541POSITIVE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY USING THE SAME - A positive active material for lithium secondary battery containing a composite that includes a composite of lithium aluminum oxide and lithium nickel oxide and lithium secondary battery using the same.01-05-2012
20120015252POSITIVE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY - Disclosed is a positive active material for a lithium secondary battery. The positive active material includes a lithium molybdenum oxide having an X-ray diffraction (XRD) pattern with peaks at 11.5±2°, 21±2°, 38±2°, and 64±2° 2-theta (2θ) and represented by Formula 1: Li01-19-2012
20120021284POSITIVE ELECTRODE AND LITHIUM BATTERY INCLUDING THE SAME - Disclosed is a positive electrode and a lithium battery including the positive electrode. The positive electrode includes a current collector, a first layer irreversibly deintercalating lithium ions, and a second layer allowing reversible intercalation and deintercalation of lithium ions. In one embodiment, the first layer further comprises a first sublayer and a second sublayer, in which the first sublayer is interposed between the current collector and the second sublayer. The first sublayer comprises a first active material represented by Formula 1 Li01-26-2012
20120021287POSITIVE ELECTRODE AND LITHIUM BATTERY INCLUDING THE SAME - Disclosed is a positive electrode and a lithium battery including the positive electrode. The positive electrode includes a first active material represented by Formula 1: Li01-26-2012

20090066624PRINTED CIRCUIT BOARD, DISPLAY APPARATUS HAVING A PRINTED CIRCUIT BOARD AND METHOD OF MANUFACTURING THE PRINTED CIRCUIT BOARD - A printed circuit board (“PCB”) includes a first pattern structure, a second pattern structure, a third pattern structure, and a fourth pattern structure. The first pattern structure includes a first ground pattern. The second pattern structure includes a first line pattern overlapping the first ground pattern and a second ground pattern electrically insulated from the first line pattern. The third pattern structure includes a third ground pattern overlapping the first line pattern and a second line pattern overlapping the second ground pattern. The fourth pattern structure includes a fourth ground pattern overlapping the second line pattern. Therefore, the PCB may decrease noise.03-12-2009
