    • A rechargeable thin film microbattery cell array of at least four thin film microbattery cells is electrically connected together in parallel to provide power as a single battery power source. The array further comprises testing logic to determine if a microbattery cell has a microbattery cell voltage that is more than a predetermined percentage different from the voltage of the overall microbattery cell array or has an absolute voltage below a predetermined cutoff threshold, and logic to disconnect any microbattery cell from the microbattery cell array if the microbattery cell has a microbattery cell voltage that is more than a predetermined percentage different from the voltage of the overall microbattery cell array or has an absolute voltage below a predetermined cutoff threshold. Embodiments also comprise a Switch Capacitor DC-DC downconverter component that reduces the voltage potential to operate some or all functionalities located on the integrated circuit.

    • A method and apparatus for making thin-film batteries having composite multi-layered electrolytes with soft electrolyte between hard electrolyte covering the negative and/or positive electrode, and the resulting batteries. In some embodiments, foil-core cathode sheets each having a cathode material (e.g., LiCoO2) covered by a hard electrolyte on both sides, and foil-core anode sheets having an anode material (e.g., lithium metal) covered by a hard electrolyte on both sides, are laminated using a soft (e.g., polymer gel) electrolyte sandwiched between alternating cathode and anode sheets. A hard glass-like electrolyte layer obtains a smooth hard positive-electrode lithium-metal layer upon charging, but when very thin, have randomly spaced pinholes/defects. When the hard layers are formed on both the positive and negative electrodes, one electrode's dendrite-short-causing defects on are not aligned with the other electrode's defects. The soft electrolyte layer both conducts ions across the gap between hard electrolyte layers and fills pinholes.
    • 一种制造薄膜电池的方法和装置,其具有在覆盖负极和/或正电极的硬质电解质之间的具有软电解质的复合多层电解质和所得电池。 在一些实施例中,每个具有由两侧硬电解质覆盖的阴极材料(例如,LiCoO 2)的箔芯阴极片和具有由硬电解质覆盖的阳极材料(例如,锂金属)的箔芯阳极片 使用夹在交替阴极和阳极片之间的软(例如,聚合物凝胶)电解质来层压两侧。 硬玻璃状电解质层在充电时获得平滑的硬质正极锂金属层,但是当非常薄时,具有随机分布的针孔/缺陷。 当硬质层形成在正极和负极上时,一个电极的枝晶短缺的缺陷与其他电极的缺陷不对齐。 软电解质层都将离子穿过硬电解质层之间的间隙并填充针孔。
