Nonaqueous electrolyte battery
View Patent ↗A nonaqueous electrolyte battery is provided which includes a battery element, and a package member for packaging the battery element, and in the nonaqueous electrolyte battery, the package member includes a layer which contains a blackbody material capable of using blackbody radiation and which has an emissivity of 0.6 or more.
1. A nonaqueous electrolyte battery comprising:
a battery element; and
a laminate film housing the battery element, the laminate film including (a) an outer layer film, a black body material layer, an adhesive layer, a metal foil and an inner layer film in that order, or (b) an outer layer film, an adhesive layer, a black body material layer, a metal foil and an inner layer film in that order,
wherein the black body material layer has an emissivity of 0.6 or more, and
wherein a blackbody material dispersed in the blackbody material layer has an average particle diameter of 1.0 μm or less.
2. The nonaqueous electrolyte battery according to claim 1 ,
wherein the inner layer film of the laminate film is a heat fusion layer.
3. The nonaqueous electrolyte battery according to claim 1 ,
wherein the adhesive layer also contains the blackbody material.
4. The nonaqueous electrolyte battery according to claim 3 ,
wherein the inner layer film has a thickness of 10 to 50 μm.
5. The nonaqueous electrolyte battery according to claim 3 ,
wherein the outer layer film includes at least one outer layer film material selected from the group consisting of a nylon (Ny), a poly(ethylene terephthalate) (PET), a poly(ethylene naphthalate) (PEN), a poly(butylene terephthalate) (PBT), and a poly(butylene naphthalate) (PBN), and the blackbody material is also dispersed in the outer layer film material.
