  • Patent number: 11522175
    Abstract: In conventional arts, it is impossible to form a good solid-solid interface in cathode mixture layers of all-solid-state batteries, which significantly deteriorates resistance of the all-solid-state battery after the charge/discharge cycle, which is problematic. A cathode slurry is produced by a method including: a first step of dispersing a conductive additive constituted of carbon in a solvent to obtain a first slurry; a second step of dispersing a sulfide solid electrolyte in the first slurry to obtain a second slurry; and a third step of dispersing a cathode active material in the second slurry to obtain a third slurry, to be used to form a cathode mixture layer. This may suppress agglomeration of the cathode active material as using the conductive additive as a core, and may lower the proportion of agglomerate present in the cathode mixture layer.

  • Patent number: 11519355
    Abstract: A misfire detection device and method for an internal combustion engine are provided. A deactivating process deactivates combustion control for air-fuel mixture in a deactivated cylinder. An instantaneous speed variable indicates a speed in a case where a crankshaft rotates by a specific angle. The specific angle of the first instantaneous speed variable is a first angle. The specific angle of the second instantaneous speed variable is a second angle greater than the first angle. A second determining process determines whether a misfire has occurred from a magnitude of a rotation fluctuation amount of a subject of determination, instead of a relative magnitude of the rotation fluctuation amount of the subject of the determination relative to a reference rotation fluctuation amount, when the reference rotation fluctuation amount is a rotation fluctuation amount of the deactivated cylinder during the execution of the deactivating process.
