摘要:
A band-shaped laminate having a flexible elongated substrate, a negative collector, a solid electrolyte, a positive active material, and a positive collector in this order is wound in a plate shape with the flexible elongated substrate placed inside. The band-shaped laminate that is laminated in a particular order is wound with the substrate placed inside, whereby a short-circuit occurrence ratio can be decreased. Furthermore, the band-shaped laminate includes the solid electrolyte, and is wound in a plate shape, whereby the reduction in thickness and the increase in volumetric energy density can be achieved.

A manufacturing method of the present invention includes ejecting a melt 61 of a solid electrolyte onto at least one electrode plate selected from a positive electrode plate 20 and a negative electrode plate 30, thereby depositing the melt 61 onto the at least one electrode plate, and compressing the positive electrode plate 20 and the negative electrode plate 30 while sandwiching the melt 61, thereby forming a layered body including the positive electrode plate 20, an electrolyte layer 62 including the solid electrolyte, and the negative electrode plate 30. In accordance with this manufacturing method, a thin lithium secondary battery having excellent characteristics can be manufactured in a highly productive manner.
摘要:
An electron beam evaporation source (42) that contains a first thin film material, an electron beam source (44) that emits an electron beam (45) to be used to evaporate the first thin film material by heating, and a resistance heating evaporation source (48) for evaporating a second thin film material by heating using a resistance heating method are arranged so that the electron beam (45) passes through a vapor stream of the second thin film material. Thus, evaporated atoms of the second thin film material can be ionized. As a result, a thin film having improved properties and increased mechanical strength can be formed. Further, since it is no longer necessary to use another device for ionizing the evaporated atoms of the second thin film material, the complication of a configuration and a cost increase can be prevented.
摘要:
A thin film layered product is composed of at least two deposition units, each of which includes at least a first thin film layer and a second thin film layer. At least one of the first thin film layer and the second thin film layer in each of the at least two deposition units is laminated so as to have an area decreased in a direction from a lower layer toward an upper layer. Thus, the reliability of connection between layers can be improved, and when a protective layer is formed on side faces, the formability and adhesion strength can be improved.

摘要:
A sheet-shaped energy device includes at least sheet-shaped battery cells, in each of which a positive collector, a negative collector, a positive active material, and an electrolyte are laminated, and a plurality of substrates in a thickness direction. An internal wiring pattern and/or an optical function part are formed on at least one substrate excluding a substrate constituting an outermost layer of the energy device among the plurality of substrates. Because of this, a constraint on the arrangement of various kinds of components used simultaneously with the sheet-shaped energy device and lengthy wiring can be reduced in electronic equipment.

摘要:
Provided is a heating apparatus including: an object to be heated under vacuum; a heating body separable from the object to be heated, the heating body being configured so that a gap is formed between the heating body itself and the object to be heated; and a gas introduction channel for introducing a heat transfer gas into the gap. The object to be heated is heated by the heating body via the heat transfer gas. An example of the heating apparatus is a deposition apparatus 30. An example of the object to be heated is a storage container 9 that holds a deposition material and that has an opening for allowing the deposition material that has been vaporized to pass therethrough. An example of the heating body is a heating container 10 that detachably accommodates the storage container 9 and that has a heater 20 for heating the deposition material in the storage container 9. An example of the gas introduction channel is the gas introduction tube 11.
