Multiple layer interlayers having enhanced optical and acoustic properties are provided, along with methods of making and using the same. Interlayers as described herein may include at least two outer skin layers and an inner core layer, with one of the outer skin layers having a different thickness than the other at one or more locations along the interlayer. The multi-layer interlayer may also exhibit acoustic properties and, in some cases, may have an overall wedged thickness profile. Additionally, in some aspects, interlayers and laminates formed therefrom may also provide reduced infrared energy transmission, without sacrificing acoustic and/or optical performance.

A polyolefin microporous film having a laminated structure provided with at least one layer A containing a polyolefin and at least one layer B containing a polyolefin. 0 mass % to less than 3 mass % of polypropylene is contained in layer A and 1 mass % to less than 30 mass % of polypropylene is contained in layer B. When the proportion of polypropylene contained in layer A is represented by PPA (mass %) and the proportion of polypropylene contained in layer B is represented by PPB (mass %), PPB>PPA. In the polyolefin microporous film, the heat shrinkage ratio in TD at 120° C. measured upon applying, in MD, a constant load determined on the basis of the relationship: load (gf)=0.01×piercing strength (gf) of polyolefin microporous film×length (mm) in TD of polyolefin microporous film, is 10 to 40% inclusive.

A resin member includes a base material and a resin molded body disposed on the base material, the resin molded body containing a main component constituted by an ethylene-vinyl acetate copolymer resin and a carbon black. The resin molded body has two or more peaks within a range of 25° C. to 80° C. in an endothermic curve obtained through measurement performed by heating from 25° C. to 150° C. at 5° C./min with a differential scanning calorimetry (DSC) apparatus.

A battery, a battery module, a battery pack, and an electric vehicle are provided. The battery includes a metal shell and a plurality of electrode core assemblies sealed in the metal shell and arranged in sequence. The electrode core assemblies are connected in series. Each of the electrode core assemblies includes at least one electrode core. The electrode core assemblies are sealed in a packaging film. An air pressure between the metal shell and the packaging film is lower than an air pressure outside the metal shell. An air pressure inside the packaging film is lower than the air pressure between the metal shell and the packaging film.
