  • Solid electrolyte for lithium battery, comprising at least one zone of lithium-containing glass ceramic material and method of production
    Patent number: 9356313
    Abstract: At least one zone made of lithium-containing glass-ceramic material, in a solid electrolyte for a lithium battery, is formed from a lithium-containing ceramic material, advantageously in the form of a layer such as a thin film. It is obtained by melting of at least a part of the lithium-containing ceramic material, followed by a recrystallization heat treatment. Melting is obtained by a laser beam irradiation operation, which enables fabrication of the solid electrolyte to be performed directly on a multilayer stack comprising certain active components of the lithium battery.
    Type: Grant

  • Integrated optical filter
    Patent number: 7880253
    Abstract: The disclosure relates to an integrated circuit comprising at least one photosensitive cell. The cell includes a photosensitive element, an input face associated with the said photosensitive element, an optical filter situated in at least one optical path leading to the photosensitive element and an interconnection part situated between the photosensitive element and the input face. The optical filter is disposed between the photosensitive element and the surface of the interconnection part closest to the input face. In particular, the optical filter can be disposed within the interconnection part. The disclosure also proposes that the filter be formed using a glass comprising cerium sulphide or at least one metal oxide.
