TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Components: The battery is formed or sputtered within the first portion of the case. The first and second portions form an enclosure having interior and exterior surfaces. The battery is formed having a contour the same as the interior surface of the first portion of the case. It is bonded to the interior surface of the first portion of the case. A protective cover is placed over the battery on the interior surface of the first portion of the case.The first and second portions are attached to one another by a living hinge. The first portion includes an electrical trace and a site adapted to receive the electrically powered component. The battery, the trace, and the electrically powered component form at least a portion of a circuit. The shell is a portion of an enclosure. The battery is formed within the shell.The electrically powered device includes contacts (65) associated with the battery. The contacts are positioned near one of the interior or exterior surface. The outer shell has a curved shape having a convex face and a concave face.Preferred Method: The desired shape includes a contoured surface corresponding to the enclosure for the electrical device. The sheet is formed by vacuum forming. The electrical traces are added to the sheet. The method includes cutting the sheet to include a desired number of battery cells; and folding the sheet after cutting to layer the battery cells. The sheet is a planar sheet during at least a portion of the fabricating function. The desired shape is non-planar. An electrically powered circuit is assembled to the sheet before or after forming the function. A motor and a light source are assembled to the sheet, where the motor and the light source are electrically coupled to the battery.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Material: The cathode layer comprises a lithium intercalation material or lithium cobalt oxide deposited on the first conductive layer. The electrolyte layer comprises lithium phosphorus oxynitride (LiPON). The anode layer comprises a lithium intercalation material deposited on the electrolyte layer.
