  • Patent number: 10096425
    Abstract: A multilayer ceramic capacitor includes a laminate constituted by internal electrode layers of different polarities alternately layered via dielectric layers, wherein the multilayer ceramic capacitor is such that the dielectric layers contain ceramic grains whose primary component is BaTiO3, the ceramic grains contain Mo, Mn, rare earth R, and at least one of V and W, and the average valence number of Mo in the ceramic grains is 4.50 to 5.50. The multilayer ceramic capacitor can offer excellent service life characteristics and sufficiently suppress leak current even when the thickness of the dielectric layer is 0.8 ?m or less.

  • Publication number: 20180115016
    Abstract: An all-solid-state battery includes a pair of electrode layers consisting of first and second electrode layers, and a solid-state electrolyte layer positioned between the pair of electrode layers, wherein the first electrode layer contains an electrode active material having an olivine-type crystalline structure, the solid-state electrolyte layer contains a solid-state electrolyte having a NASICON-type crystalline structure, and the solid-state electrolyte layer in the vicinity of the first electrode layer is expressed by a composition formula LixAyCozM?aM?bP3Oc. The all-solid-state battery can improve the long-term cycle stability.

  • Publication number: 20170032895
    Abstract: A multilayer ceramic capacitor includes a laminate constituted by internal electrode layers of different polarities alternately stacked via dielectric layers, wherein the multilayer ceramic capacitor is such that the dielectric layers contain ceramic grains whose primary component is BaTiO3, the ceramic grains contain Mo, Mn, and rare earth R, and the average valence number of Mo in the ceramic grains is 4.18 to 4.60. The multilayer ceramic capacitor can offer excellent service life characteristics and bias characteristics even when the thickness of the dielectric layer is 0.8 ?m or less.
