A battery pack and an electric vehicle are provided. The battery pack includes a battery sequence. The battery sequence includes multiple cells. A thickness of each cell extends along a first direction. The multiple cells are arranged in sequence along the first direction to form the battery sequence. At least one of the cells includes a metal shell and an electrode core packaged in the metal shell. An air pressure inside the metal shell is lower than an air pressure outside the metal shell. A gap is provided between at least two adjacent cells. A ratio of the gap to the thickness of the cell ranges from 0.001 to 0.15.

The invention relates to an insulated panel, in particular a wall panel or roof panel, including a foamed core layer and a cover layer affixed to the foamed core layer. The invention also relates to an insulating covering, in particular a wall covering or floor covering, including a plurality said insulated panels.

To obtain a decorative sheet having excellent fingerprint resistance of the decorative sheet surface, a decorative plate, and a method for producing a decorative sheet. A decorative sheet includes: a primary film layer; a colored pattern layer provided on one surface of the primary film layer; and a first surface protective layer provided on the surface on the side opposite to the primary film layer of the colored pattern layer, having a core part and ridge-like parts provided to project in a ridge-like shape from one surface of the core part, and having an irregular shape formed on the surface. The first surface protective layer of the decorative sheet is formed by irradiating a surface of an applied ionizing radiation curable resin with a first ionizing radiation having energy capable of cleaving a polymer chain of the ionizing radiation curable resin, to shrink the surface of the ionizing radiation curable resin, and form an irregular shape on the surface of the ionizing radiation curable resin, and irradiating the shrunk ionizing radiation curable resin with a second ionizing radiation curing the ionizing radiation curable resin to cure the ionizing radiation curable resin.

An elastomeric composition, including at least one skin layer and a core layer, with non-blocking properties such that the elastomeric composition can be wound is provided. The core layer includes an elastomer, and the skin layer includes an elastomer, which may be the same or different from the core layer, and a non-elastic polyolefin. Further, the skin layer can be present as a small portion of the total elastomeric composition, and may maintain the elastic efficiency of the composition.

A decorative sheet for vacuum forming is difficult to peel off during vacuum forming between a first vinyl chloride-based resin layer and a second vinyl chloride-based resin layer and can give a design of various colors. This decorative sheet for vacuum forming includes: a first vinyl chloride-based resin layer containing a vinyl chloride-based resin and a coloring agent; and a second vinyl chloride-based resin layer which is laminated on the first vinyl chloride-based resin layer, contains a vinyl chloride-based resin, and is transparent, wherein the content of titanium oxide particles of the coloring agent is less than 1 part by mass, the first vinyl chloride-based resin layer contains inorganic particles, and at least some of the inorganic particles are calcium carbonate particles.
