  • Publication number: 20240065600
    Abstract: An emotion estimating device, an emotion estimating system, and an emotion estimating method capable of estimating an emotion of a subject based on information obtained from daily activities can be provided. An emotion estimating device includes an interface that receives input of walking data of a subject measured by a measurement device and emotion data obtained by quantifying the emotion of the subject, a storage that stores the walking data and the emotion data, and an computer that obtains corresponding data in which a plurality of walking parameters included in the walking data stored in the storage are associated with the emotion data. When the interface newly receives the input of the walking data, the computer estimates the emotion of the subject from the plurality of walking parameters included in the newly received walking data, and outputs information indicating the estimated emotion of the subject.

  • Patent number: 10193159
    Abstract: A current collector for a secondary battery (1) of the present invention includes a resin layer (2) having electrical conductivity, and an ion barrier layer (3) provided on the surface of the resin layer (2). The ion barrier layer (3) contains ion trapping particles (6) in which metal compounds (5) are provided on the surfaces of metal containing particles (4). The ion trapping particles (6) are continuously provided from an interface (7) between the resin layer (2) and the ion barrier layer (3) toward a surface (3a) of the ion barrier layer (3). Thus, the ion barrier layer (3) prevents from the entry of ions, so that the ion adsorption in the current collector (1) can be decreased.

  • Patent number: 9666858
    Abstract: A negative electrode for a secondary battery according to the present invention has a collector and a negative electrode active material layer formed on a surface of the collector and containing negative electrode active material particles. In the negative electrode active material layer, an insulating material is arranged between the negative electrode active material particles so as not to develop conductivity by a percolation path throughout the negative electrode active material layer. It is possible in this configuration to effectively prevent the occurrence of a short-circuit current due to an internal short circuit and the generation of heat due to such short-circuit current flow in the secondary battery while securing the battery performance of the secondary battery.

  • Patent number: 9077040
    Abstract: To provide a method that is capable of suppressing absorption of lithium ions into the inner portion of a resin collector that is used in a bipolar lithium ion secondary battery. The collector for a bipolar lithium ion secondary battery of the invention has at least two conductive layers. One of the conductive layers that constitute the collector (a first conductive layer) is configured by adding a conductive filler into a base material that contains an imide group-containing resin. The other of the conductive layers that constitute the collector (a second conductive layer) is configured by adding a conductive filler into a base material that contains a polar resin containing no imide group. The collector for a bipolar lithium ion secondary battery is further characterized in that when a bipolar electrode is formed, the first conductive layer is arranged on the positive electrode side.
