摘要： An ultra-high-efficiency switching power supply system integrating, into a single package, power conversion switches for multiple power supplies, an input power switching block, an output power switching block, control logic for controlling the power conversion switches and control input/output ports. This integrated multiple power supply package is called a Power Bridge and preferably implements the integrated components as one or more integrated circuit chips housed in the package housing. The Power Bridge is a bridge between the microprocessor of a portable computer and its internal and external power sources. The power supply system facilitates board design because the ultra-high-efficiency power module generally requires less space and generates less heat than conventional power supply circuitry. The power supply module improves power management because of improved communications connections between the power supply module control circuitry and other components, such as busses, other bridge modules and embedded controllers.

摘要： A matted particulate electrode located between the current collector and a porous separator of a rechargeable lithium battery is described, which contains electro-active particles intermixed with pliable, solid, lithium ion conducting, polymer electrolyte filaments having adhesive surfaces. The electro-active particles and the optionally added electro-conductive carbon particles adhere to the tacky surface of the adhesively interlinking polymer electrolyte filaments. The matted particulate electrode is impregnated with an organic solution containing another lithium compound. In a second embodiment the porous separator is coated on at least one of its faces, with polymer electrolyte having an adhesive surface and made of the same polymer as the electrolyte filaments. The polymer electrolyte filaments in the matted layer may adhere to the coated surface of the separator. In addition the polymer coating is partially filling the pores of the porous electrolyte, but leaving sufficient space in the pores for the organic solution to penetrate the separator of the lithium battery.

摘要： The terminals of a thin plate rechargeable lithium battery are coated with a heat-sealable polymer. The coating forms a band on each face of the terminals and the band is heat-sealed to the inner insulator layers of a multi-layered polymer laminate enclosing the thin plate rechargeable lithium battery at a location close to an open edge of the insulator layer. Small sheets of rigid, high melting point, polymeric materials are inserted between the bands of coating carried by the terminals and the edge of the multi-layered laminate enclosing the lithium battery. A portion of the sheets of polymeric material is adhesively attached to the face of the terminal adjacent the bands of coating. The open edges of the multi-layered polymer laminate enclosure are subsequently sealed to enclose completely the thin plate lithium battery.
