摘要:
An energy storage device includes a housing having an interior surface defining a volume and a plurality of solid electrolyte elements disposed in the volume. Each solid electrolyte element has a first surface that defines at least a portion of a first, cathodic chamber, and a second surface that defines a second, anodic chamber. A plurality of individual anodic chambers are thus provided, at least one of which is evacuated below atmospheric pressure. A majority of anodic chambers can be spaced from one another in a manner that provides a substantially uniform reaction rate throughout the cathodic chamber. The housing and the plurality of solid electrolyte elements together may be configured to define a second volume devoid of solid electrolyte elements and that is sufficient in size to accommodate a desired number of solid electrolyte elements and to provide an accessible cathodic chamber filling point and that is further sufficient in size to alter the volume of the cathodic chamber with respect to the volume of the plurality of anodic chambers to achieve a desired volumetric ratio between the cathodic and anodic chambers.

Processes for simultaneously encapsulating multiple optoelectronic devices and/or depositing a barrier film onto multiple substrates suitable for fabrication of optoelectronic devices thereon include the use of a plasma deposition apparatus having multiple pairs of opposing electrodes for deposition of reactants onto the substrate that is used to form the device or the complete device itself. The processes significantly reduce tact time relative to one at a time batch processing that is currently used for manufacturing optoelectronic devices.

Provided are organic device packages configured to limit current flow through shorted sub-elements in the organic device. In some embodiments, the organic device package may include multiple elements, each having multiple sub-elements connected in parallel. Each element may have a first electrode patterned into thin electrode strips connected in parallel, and each of the electrode strips may be an electrode of one of the multiple sub-elements. The electrode strips may have a resistance which may be higher than the overall resistance of other sub-elements in the element, such that a current flowing to the element may be substantially limited from flowing through a shorted sub-element in the element. Each element may also be connected in series to another element in the organic device package, and one or more series-connected elements may also be connected in parallel within the package.

摘要:
The invention relates to composite articles comprising a substrate and additional layers on the substrate. According to one example, the layers are selected so that the difference in the coefficient of thermal expansion (CTE) between the substrate and a first layer on one side of the substrate is substantially equal to the CTE difference between the substrate and a second layer on the other side of the substrate. The stress caused by the CTE difference and/or shrinkage on one side of the substrate during heating or cooling is balanced by the stress caused by the CTE difference on the other side of the substrate during heating or cooling. Such stress balancing can reduce or minimize curling of the substrate.
