Long life, low power, multicell battery

With the increased need to power portable electronic devices for long extended periods, a new approach needs to be taken for finding suitable battery technologies to meet this objective. This STTR proposal utilizes a novel miniature reserve battery design based on recent research in the manipulation of fluids on superhydrophobic nanostructured surfaces, to achieve the performance and life cycle objectives to power the SRAM module requirements of this proposal. In our design, long term stability and shelf life is achieved by initially separating the active materials of the power cell during storage, and controlling the activation of the cell until needed to provide power. In Phase 1 we will characterize the design, conduct capacity and stability measurements of a reserve style power cell based on Li/Mn02 chemistry and set the stage for a Phase 2 plan for an arrayed battery configuration capable of powering the SRAM for long term continuous use in temperature ranges from -400C to greater than 1000C.
