    摘要: A battery includes a battery body having a body top surface, a body bottom surface, and a body side wall. The body side wall includes two oppositely disposed first side walls. Distance between outer surfaces of the two first side walls is L. First and second positions not coincide with each other are taken on midline of any first side wall, the first position is located in a range of 0 to 10 mm from the body top surface, the second position is located in a range of 0 to 10 mm from the body bottom surface, and distance between the first and second positions is H. Under conditions of ambient temperature being 25° C. and 2C current rate, temperature at first position is T1, temperature at second position is T2, and the battery satisfies (T1−T2)×3L/H≤20° C.

    摘要: A battery packaging material is formed of a laminate. The laminate is composed of an outer layer including a substrate layer, a barrier layer as an intermediate layer, and a heat fusible resin layer as an innermost layer. The total thickness of the laminate is 60 μm to 220 μm. The barrier layer is formed of a metal foil. The product of a stress value and a thickness of the heat fusible resin layer at a time of 10% stretching is 1,200 Pa·m or more.

    摘要: A structured battery having a battery core disposed between two carbon fiber layers. The battery core includes one or more layers of graphene battery sheets configured to store electricity. The structured battery also includes a honeycomb layer configured to transfer heat from the one or more layers of graphene battery sheets to the carbon fiber layers. The structured battery can be used as a structural component such as components of an electric vehicles, components of a building, or components of an appliance.
