  • Patent number: 11043660
    Abstract: A positive electrode active material which can improve cycle characteristics of a secondary battery is provided. Two kinds of regions are provided in a superficial portion of a positive electrode active material such as lithium cobaltate which has a layered rock-salt crystal structure. The inner region is a non-stoichiometric compound containing a transition metal such as titanium, and the outer region is a compound of representative elements such as magnesium oxide. The two kinds of regions each have a rock-salt crystal structure. The inner layered rock-salt crystal structure and the two kinds of regions in the superficial portion are topotaxy; thus, a change of the crystal structure of the positive electrode active material generated by charging and discharging can be effectively suppressed.

  • Patent number: 11038135
    Abstract: Provided is a light-emitting element with high external quantum efficiency, or a light-emitting element with a long lifetime. The light-emitting element includes, between a pair of electrodes, a light-emitting layer including a guest material and a host material, in which an emission spectrum of the host material overlaps with an absorption spectrum of the guest material, and phosphorescence is emitted by conversion of an excitation energy of the host material into an excitation energy of the guest material. By using the overlap between the emission spectrum of the host material and the absorption spectrum of the guest material, the energy smoothly transfers from the host material to the guest material, so that the energy transfer efficiency of the light-emitting element is high. Accordingly, a light-emitting element with high external quantum efficiency can be achieved.

    Abstract: The solar charging system according to the present embodiment includes a solar panel, a drive battery, an auxiliary system including one or more devices, and a controller that controls where to supply power generated by the solar panel. The controller determines whether the solar panel can generate power, and, upon determining that the solar panel can generate power, supplies the power from the solar panel to the auxiliary system to derive the power generated by the solar panel. Upon detecting a fact that the power generated by the solar panel is equal to or greater than a first power, the controller further supplies the power from the solar panel to the drive battery to charge the drive battery.
