Abstract:
Systems and methods for producing a multilayer thin film energy storage device having a plurality of thin film battery cells arranged to provide a higher output than a single cell thin film battery. The thin film battery cells are configured so that they stacked one on another with at least one thin film battery cell positioned upside down on top of another thin film battery cell. Alternatively, the thin film battery cells may be arranged in a side-by-side configuration. Each thin film battery cell includes a thin film layer of cathode material and anode material with an electrolyte material disposed between and separating the cathode material and anode material. A thin film current collector is positioned adjacent to each cathode and anode thin film layer. The particular pattern of thin films of current collectors, anodes, electrolytes and cathodes serves to a provide a high output necessary for particular applications. The multilayer energy storage device is produced using an aligning drum system having a web of thin film cells wound therein that allows each thin film layer to be deposited onto a substrate. The output is a sheet containing a plurality of multilayer energy storage devices that can be separated from the sheet to produce an individual multilayer energy storage device. Furthermore, cutting between the stacked layers of multilayer energy storage devices produces individual thin film battery cells.
Abstract:
A method and system for fabricating solid-state energy-storage devices including fabrication films for devices without an anneal step, especially a cathode anneal of thin-film batteries. A film of an energy-storage device is fabricated by depositing a first material layer to a location on a substrate. Energy is supplied directly to the material forming the film. The energy can be in the form of energized ions of a second material. Supplying energy directly to the material and/or the film being deposited assists the growth of the crystalline structure of film. For lithium-ion energy-storage devices, the first material is an intercalation material, which releasably stores lithium ions therein. Supercapacitors and energy-conversion devices are also fabricated according the methods.
Abstract:
Cracking or the like is prevented from being formed in an outer wall of a container of a closed battery module whose internal space is divided by partitions. Each partition dividing the internal space of the container of the closed battery module is provided with a deformable portion that deforms before a stress greater than an allowable value is caused in a container outer wall by load applied to the container. When a load is applied to the module container, the partitions dividing the container internal space restrict deformation of the container outer walls, so that great stress is likely to occur in the outer walls. However, as the deformable portion of a partition deforms due to such load, the stress caused in the container outer walls decreases, so that formation of a crack or the like in the container outer walls becomes less likely.
Abstract:
A battery comprises a plurality of connected, thin cells mounted in a band of a watch. Each cell is (or a unit of cells are) disposed in one of a plurality of links of a watchband of the watch or either one of two snapping members at ends of the watchband. The invention is also applicable in wrist antennas, mobile phones, or digital cameras.
Abstract:
An electrochemical cell laminate is disclosed which comprises an electrolyte separator, a cathode film and a cathode current collector, a metallic anode film, and an insulating support film onto which the cathode film and the cathode current collector are coated onto a first surface thereof and the metallic anode film is positioned onto a second surface thereof. The cathode film and the anode film being electrically and ionically isolated from each other by the insulating support film. The electrochemical cell laminate according to the invention may be stacked wound or rolled to form an electrochemical battery.
Abstract:
A process for producing a battery (10) containing electrochemical cells is distinguished by the fact that an electrically non-conductive track (30) or a similar coating is applied to the respective free edge region (26) of the two housing parts (12.1, 12. 2) between which the anode and cathode lugs (18) are guided out of the battery housing (12), in such away that it (30) is present at least in the regions of the lugs (18), and that it project beyond the free edge (20) of the housing part (12.1, 12.2) to which it is attached and/or engages around this free edge.
Abstract:
Sheet batteries are connected in series, layered and sandwiched between an upper substrate and a lower substrate, and the sheet batteries, the upper substrate and the lower substrate form a layered substrate with the batteries. Holes for wires of ICs are formed in the layered substrate. Applied voltages are determined according to batteries to which the holes are formed. The voltages of the sheet batteries may be uniform, or different.
