  • Publication number: 20100273056
    Abstract: A lithium battery that contains a solid electrolyte but has a high capacity is provided. A lithium battery 1 includes: a positive-electrode layer 13; a negative-electrode layer 14; and a sulfide solid electrolyte layer (SE layer 15) provided between the layers 13 and 14. The lithium battery 1 has a positive-electrode covering layer 16 and a buffer layer 17 formed between the layers 13 and 15 for suppressing nonuniformity of distribution of lithium ions in a region near the interface between the layers 13 and 15. In the battery 1, the positive-electrode covering layer 16 contains LiCoO2 whereas the positive-electrode layer 13 does not contain LiCoO2.

  • Publication number: 20100106830
    Abstract: A statistical-data collecting-and-providing apparatus receives, through a statistical-data-acquisition-criterion setting interface, setting of a statistical-data acquisition criterion and setting of a notification destination, which is a destination of statistical data delivery. Subsequently, the statistical-data collecting-and-providing apparatus collects statistical data based on the thus-received statistical-data acquisition criterion. Thereafter, the statistical-data collecting-and-providing apparatus delivers the thus-collected statistical data to a service-providing application server, which is the notification destination received through the statistical-data-acquisition-criterion setting interface.

  • Publication number: 20100028775
    Abstract: The battery of the invention has a positive-electrode layer 20, a negative-electrode layer 50, and an electrolytic layer 40 through which ionic conduction is performed between the two electrode layers. In this battery, the positive-electrode layer 20 and the negative-electrode layer 50 are laminated with each other and an insulating layer 30 is placed between the positive-electrode layer 20 and the negative-electrode layer 50. The insulating layer 30 has an area smaller than that of one of the positive-electrode layer 20 and the negative-electrode layer 50 and larger than that of the other. There is no place where the positive-electrode layer 20 and the negative-electrode layer 50 face each other through only the electrolytic layer 40. Even when the electrolytic layer 40 has a pinhole, the presence of the insulating layer 30 between the positive-electrode layer 20 and the negative-electrode layer 50 can suppress short-circuiting between the positive- and negative-electrode layers.

  • Patent number: 7618744
    Abstract: A thin film lithium battery is provided which can realize a high yield by solving various problems caused by a pin hole formed in a solid electrolyte layer. A thin film lithium battery according to the present invention is a thin film lithium battery in which a positive electrode layer 20, a negative electrode layer 50, a solid electrolyte layer 40 provided therebetween, and a collector 10 electrically connected to at least one of the positive electrode layer 20 and the negative electrode layer 50 are laminated to each other. When this battery is viewed in plan along the lamination direction of the above individual layers, the positive electrode layer 20 and the negative electrode layer 50 are disposed at positions so as not to be overlapped with each other. By the structure as described above, even if a pin hole is formed in the solid electrolyte layer 40, short-circuiting between the two electrode layers 20 and 50, which is caused by this pin hole, can be prevented.

  • Patent number: 6939518
    Abstract: A purifier to purify exhaust gas includes a case, a plurality of metal sheets disposed in the case, a catalyst held to each of the metal sheets, partition plates disposed between the respective metal sheets, a metallic pipe disposed piercing through the metal sheets, and a catalyst heater disposed in the metallic pipe. The plurality of metal sheets are arranged at predetermined intervals, and each of the metal sheets has at least one through-hole. The partition plates serve to partition the spaces between the respective metal sheets. The exhaust gas is circulated through the spaces between the respective metal sheets and then passes through the through-holes and is exhausted from the outlet of the case. In this way, it is possible to increase the number of metal sheets without increase of the pressure loss and to enlarge the outer diameter of same. As a result, the exhaust gas purifying capacity will be improved.
