    Abstract: A power storage device a positive electrode including a positive electrode active material layer and a negative electrode including a negative electrode active material layer. The positive electrode active material layer includes a plurality of particles of x[Li2MnO3]-(1−x)[LiCo1/3Mn1/3Ni1/3O2] (obtained by assigning 0.5 to x, for example) which is a positive electrode active material, and multilayer graphene with which the plurality of particles of the positive electrode active material are at least partly connected to each other. In the multilayer graphene, a plurality of graphenes are stacked in a layered manner. The graphene contains a six-membered ring composed of carbon atoms, a poly-membered ring which is a seven or more-membered ring composed of carbon atoms, and an oxygen atom bonded to one or more of the carbon atoms in the six-membered ring and the poly-membered ring, which is a seven or more-membered ring.

    Abstract: To provide a lithium-ion secondary battery which has high charge and discharge capacity, is capable of being charged and discharged at high rate and has good cycle characteristics. A negative electrode includes a current collector and a negative electrode active material layer. The current collector includes a plurality of protrusion portions extending in the direction substantially perpendicular to the current collector and a base portion connected to the plurality of protrusion portions. The protrusion portions and the base portion are formed using the same material containing titanium. At least side surfaces of the protrusion portions are covered with the negative electrode active material layer. In the negative electrode active material layer, silicon layers and silicon oxide layers are alternately stacked between a plane where the protrusion portions are in contact with the negative electrode active material layer and a surface of the negative electrode active material layer.

    Abstract: Provided are a data processing device and a data processing method that allow selecting and performing of an appropriate operation according to user's emotions. A user's face is detected and features of the user's face are extracted from data on the detected face. The user's emotions are estimated from the extracted facial features, and data based on the estimated user's emotions is generated. Whether the generated data is transmitted to an external device is determined on the basis of positional data of the user and the external device including a data reception unit, which is included in a radio wave transmitted from the Global Positioning System. When it is determined that the generated data is transmitted, it is transmitted to the external device. The external device that has received the data selects and executes operation based on the received data.
