  • Publication number: 20190194537
    Abstract: A color conversion composition is configured to convert incident light into light having a wavelength longer than that of the incident light. The color conversion composition includes: an organic luminescent material (A) having a full width at half maximum of a peak of 10 nm or larger and 50 nm or smaller, the peak indicating a maximum radiant intensity in an emission spectrum; and a resin (B) having an alicyclic structure, a ratio of a repeating unit having the alicyclic structure in the resin being 50% by weight or higher in a total amount of the resin.

  • Publication number: 20190030428
    Abstract: A program, embodied on a non-transitory computer-readable medium, which causes an information processing device that executes a game to execute: a step of causing an interface that accepts a user operation to be displayed; a step of storing first information related to game content on the basis of the user operation that is accepted by the interface; a step of storing second information related to game content that is selected among a plurality of items of game content by game content selection processing and is associated with a user; a step of comparing the first information and the second information; a step of causing a comparison result of the first information and the second information to be displayed; and a step of making a predetermined game effect capable of being exhibited in the game on the basis of comparison of the first information and the second information.

  • Publication number: 20180316040
    Abstract: A method of producing a lithium ion secondary battery includes preparing a case in which an electrode group including at least a positive electrode and a negative electrode is accommodated; impregnating a first electrolyte solution into the electrode group, lowering a potential of the negative electrode to a first potential, injecting FEC into a case, and lowering a potential of the negative electrode to a second potential. The negative electrode contains at least graphite and silicon oxide. The first electrolyte solution does not contain FEC. An additive has a reductive decomposition potential of 0.5 V (vs. Li+/Li) or more and 1.5 V (vs. Li+/Li) or less. The first potential is higher than 0.2 V (vs. Li+/Li) and is equal to or lower than the reductive decomposition potential. The second potential is 0.2 V (vs. Li+/Li) or less.

  • Publication number: 20180108938
    Abstract: A method of manufacturing a non-aqueous electrolyte secondary battery includes: (A) constructing an electrode group including a positive electrode and a negative electrode; (B) impregnating the electrode group with a first electrolyte solution; (C) charging the electrode group impregnated with the first electrolyte solution to a voltage of 4.3 V or more; and (E) manufacturing the non-aqueous electrolyte secondary battery by impregnating the electrode group with a second electrolyte solution after the charging. The first electrolyte solution includes a first solvent, a first lithium salt, and biphenyl. The first solvent does not include 1,2-dimethoxyethane. The second electrolyte solution includes a second solvent and a second lithium salt. The second solvent includes 1,2-dimethoxyethane.

  • Patent number: 8831822
    Abstract: A battery management system includes: measuring a surface pressure of a vehicle-mounted secondary battery (battery cell) for driving the vehicle with a lapse of time; calculating a high-rate driving frequency coefficient on the basis of the measured surface pressure at intervals of a predetermined period (24 hours); deriving a high-rate driving frequency on the basis of the number of times that the calculated high-rate driving frequency coefficient has exceeded a predetermined threshold; and selecting a replacement battery from among batteries including a high-power battery on the basis of the derived high-rate driving frequency.
