    Abstract: The present disclosure relates to an electrolyte for a lithium metal battery including a reductive decomposable additive for forming a stable film, and a lithium metal battery including the same. The electrolyte for the lithium metal battery includes lithium nitrate (LiNO3) and lithium difluorobis(oxalate) phosphate (LiDFBP) as a reductive decomposable additive, so that a stable protective film is formed on the surface of a metal anode. Accordingly, mechanical properties are improved so as to withstand lithium volume expansion under a high-specific-capacity condition, and ion conductivity is improved under a high-current-density condition, thereby improving the stability and performance of the lithium metal battery including the protective film.

  • Patent number: 7667404
    Abstract: A plasma display apparatus is provided. Polygonal discharge cells are arranged in delta. Extension parts are extended from pairs of sustain electrodes that apply a voltage to the discharge cells to discharge spaces to face each other. Since the extension parts have at least one depressed parts, the efficiency of sustain discharge improves due to a long gap. Since the width of data electrodes formed under the discharge cells is large in the discharge spaces, a distance between the effective side surfaces of the pairs of sustain electrodes and the data electrodes is reduced so that the efficiency of address discharge improves.

  • Patent number: 6819307
    Abstract: A plasma display panel and a driving method thereof that are capable of improving the brightness and the discharge efficiency. In the plasma display panel, an auxiliary electrode pair causes an auxiliary discharge. An area of the auxiliary electrode at the periphery of a discharge cell is wider than that at the center of the discharge cell. A sustaining electrode pair is arranged at each side of the auxiliary electrode pair to cause a sustaining discharge by utilizing the auxiliary discharge. In the driving method, wall charges concentrate on the center portion of the discharge cell during an auxiliary discharge generated between the auxiliary electrode pair. Then, a sustaining discharge is generated between the sustaining electrode pair by utilizing the wall charges produced by the auxiliary discharge.

  • Patent number: 6608447
    Abstract: A plasma display panel and a driving method thereof is adaptive for realizing high efficiency. In the plasma display panel, a sustaining electrode pair and an address electrode are included in each discharge cell. A first dielectric layer covers the sustaining electrode pair. To induce a discharge of the sustaining electrode pair, a floating electrode pair is formed parallel thereto on the first dielectric layer. A second dielectric layer and a protective film cover the floating electrode pair. Accordingly, two auxiliary electrodes are provided between the sustaining electrode pair so that when a voltage is applied to the sustaining electrode pair, the voltage is driven into the auxiliary electrodes. A primary discharge is thus induced between said auxiliary electrodes at a low voltage and therefore a long-path discharge is induced between the sustaining electrode pair at a low voltage, even though they are distanced apart from each other.
