Abstract: To form graphene to a practically even thickness on an object having an uneven surface or a complex surface, in particular, an object having a surface with a three-dimensional structure due to complex unevenness, or an object having a curved surface. The object and an electrode are immersed in a graphene oxide solution, and voltage is applied between the object and the electrode. At this time, the object serves as an anode. Graphene oxide is attracted to the anode because of being negatively charged, and deposited on the surface of the object to have a practically even thickness. A portion where graphene oxide is deposited is unlikely coated with another graphene oxide. Thus, deposited graphene oxide is reduced to graphene, whereby graphene can be formed to have a practically even thickness on an object having surface with complex unevenness.

Abstract: A power storage device that can be discharged safely and easily is provided. The power storage device includes a secondary battery covered with an exterior body, a radiator plate in contact with a surface of the exterior body, and a projection. The projection has conductivity and is held over the exterior body in the normal condition. When the projection penetrates the exterior body to be inserted into the secondary battery, the secondary battery can be short-circuited and discharged. Heat can be efficiently released from the projection to the radiator plate. Thus, the secondary battery can be discharged safely at high speed without thermal runaway.

Abstract: Graphene is formed with a practically uniform thickness on an uneven object. The object is immersed in a graphene oxide solution, and then taken out of the solution and dried; alternatively, the object and an electrode are immersed therein and voltage is applied between the electrode and the object used as an anode. Graphene oxide is negatively charged, and thus is drawn to and deposited on a surface of the object, with a practically uniform thickness. After that, the object is heated in vacuum or a reducing atmosphere, so that the graphene oxide is reduced to be graphene. In this manner, a graphene layer with a practically uniform thickness can be formed even on a surface of the uneven object.

Abstract: A novel semiconductor device or a semiconductor device capable of preventing overcharging is provided. A power receiving portion has a function of generating a signal for canceling a wireless signal transmitted from a power feeding portion when the charging is completed. Specifically, when the remaining battery capacity of the power receiving portion is one hundred percent or higher than or equal to a predetermined reference value, the power receiving portion has a function of generating an electromagnetic wave for canceling an electromagnetic wave transmitted from the power feeding portion. Thus, a magnetic field for canceling a magnetic field formed of the electromagnetic wave transmitted from the power feeding portion is formed, so that overcurrent in the power receiving portion can be prevented.

Abstract: As a display device has higher definition, the number of pixels is increased and thus, the number of gate lines and signal lines is increased. When the number of gate lines and signal lines is increased, it is difficult to mount IC chips including driver circuits for driving the gate lines and the signal lines by bonding or the like, whereby manufacturing cost is increased. A pixel portion and a driver circuit for driving the pixel portion are provided on the same substrate, and at least part of the driver circuit comprises a thin film transistor including an oxide semiconductor sandwiched between gate electrodes. A channel protective layer is provided between the oxide semiconductor and a gate electrode provided over the oxide semiconductor. The pixel portion and the driver circuit are provided on the same substrate, which leads to reduction of manufacturing cost.
