A battery is provided that includes a laminate film having a metal layer and a thermal adhesive resin layer, a battery element which is covered with the laminate film, and leads which are connected to the battery element. The leads are sandwiched between opposing thermal adhesive resin layers, and extend outside the laminate film. The thermal adhesive resin layer has thermal adhesive resin and fine resin fibers.

Battery and battery pack

A nonaqueous electrolyte battery and a battery package are provided. The nonaqueous electrolyte battery includes a battery element; a nonaqueous electrolyte; and a battery package configured to accommodate the battery element, wherein the battery package includes a first layer; a second layer including a carbon material; and a metal layer, wherein the second layer is directly provided on the metal layer.

Battery package including blackbody material layer and nonaqueous electrolyte battery including the same

The present invention provides a battery, a method of forming a battery cell container, and an electronic device. The battery of the present invention comprises: a battery cell, and a battery cell container composed of two folded container portions formed by stretching in one thin sheet, wherein, in each container portion, among the planes where the walls of each container exist, at least two planes are inclined to the plane where the thin sheet section for forming the container portion exists. Through the implementation of the present invention, a larger volume of battery container can be obtained with the same or less material as well as easy positioning.

Battery, method of forming a battery cell container, and electronic device

A package for a battery is provided. The package includes a first material layer; a black material layer including a blackbody material; and a metal layer, wherein the black material layer has a color different than the metal layer and is provided between the first material layer and the metal layer. A battery including the package is further provided.

Battery and a package for a battery

A battery capable of inhibiting swollenness of the battery is provided. A cathode and an anode are layered with a separator and an electrolyte layer in between. The anode contains an anode active material containing Sn or Si as an element. The electrolyte layer contains an electrolytic solution and a high molecular weight compound. It is preferable that the distance between the cathode and the anode is from 15 &#x3bc;m to 50 &#x3bc;m, and the distance between the cathode and the separator and the distance between the anode and the separator are respectively from 3 &#x3bc;m to 20 &#x3bc;m. Thereby, expansion of the anode is absorbed, stress on the anode is reduced, and occurrence of wrinkles in the anode is inhibited.

Battery anode containing CoSnC material

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.

Nonaqueous electrolyte battery

An electrode includes: a collector; and an active material layer provided on the collector, containing a copolymer obtained by copolymerizing, as a comonomer, at least one member selected from monomers represented by the following general formulae (1) to (4) with vinylidene fluoride or vinylidene fluoride and a copolymerizable monomer thereof 

Electrode and battery having the same

A battery pack including a battery cell, a circuit board electrically connected to the battery cell, a first cover, and a second cover. The battery cell includes a battery element, a rectangular first packaging component, a recess, and a rectangular second packaging component. The battery element is housed in the recess, the first packaging component and the second packaging component are stacked so that the second packaging component covers the opening of the recess, the periphery of the opening is sealed, both ends of the second packaging component are abutted at the outer bottom surface of the recess of the first packaging component, and the first outer resin layer and the second inner resin layer are bonded by heat seal adhesive layer.

Battery pack and method of manufacturing the same

A laminated packaging material and a battery using the material are disclosed. The material includes an inner layer composed of a resin film, a first adhesive layer, a metal layer, a second adhesive layer, and an outer layer composed of a resin film. At least one of the first adhesive layer or the second adhesive layer is composed of an adhesive composition, as an essential component, selected from the group consisting of a resin having an active hydrogen group in a side chain, polyfunctional isocyanates, and a polyfunctional amine compound.
