Abstract: An anode environment mitigates undesired effects of oxygen upon the anode of a lithium-oxygen electrochemical cell. As a means of mitigating oxygen effect, a lithium anode and an air cathode are separated from one another by a lithium-ion-conductive electrolyte separator including material having low oxygen permeability that reduces the amount of oxygen that contacts the anode. As another means of mitigating oxygen effect, a cell comprises lithium-affinity anode material capable of receiving and retaining lithium in a state that is not significantly adversely affected by the presence of oxygen during cell charging and recharging and an air cathode separated by a lithium-ion-conductive electrolyte separator. Lithium-affinity material is capable of drawing lithium thereinto during charging of the cell and retaining the lithium substantially until discharge of the cell.

Abstract: Systems and methods for an integrated circuit that reduces switching noise including an inverter network having at least two transistors, a micro-battery, such as a thin film battery, coupled to the inverter network and a resistor coupled at one end to the micro-battery and connected to a power source at the other end. When the transistors transition from one logic state to another logic state, for a period of time more than one transistor is turned on. Unless controlled, this state produces a high amount of current and a resultant voltage spike. The current demanded during this transition period is drawn from the micro-battery preventing a peak voltage flowing to and disrupting the analog components. The battery re-charges gradually and thus, no voltage spike occurs. Further, integrated circuit components are isolated from the power line by the resistor that limits the current drawn on the line.
