Polymeric rechargeable solid-state proton battery
Journal of Power Sources, 2006Co-Authors: Rana Pratap, Baljit Singh, S. ChandraAbstract:Rechargeable proton conducting polymeric solid-state batteries have been fabricated with the configuration Zn + ZnSO4·7H2O || PEO:NH4ClO4+ PC || V2O5+ PbO2+ C + E. The maximum cell voltage is ∼1.57 V at full charge. The discharge characteristics of the cell have been studied at different loads. The cell remains stable for more than 180 h for low Current Drain (∼μA) making it suitable for low Current density application. The cell also showed a good rechargeability which was tested for nine cycles. © 2006.

Rechargeable solid-state battery using a proton-conducting composite as electrolyte
Journal of Power Sources, 2002Co-Authors: N Lakshmi, S. ChandraAbstract:Proton-conducting composites of heteropolyacid hydrates (phospbotungstic acid, PTA and phosphomolybdic acid, PMA) with dispersoids such as insulating Al2O3, Al2(SO4)3·16H2O and (NH4)10W12O41·2H2O are prepared for use as possible solid-state electrolytes in batteries. Bulk electrical conductivity as a function of composition is reported. Rechargeable solid-state proton batteries are fabricated and characterized. A cell with the configuration Zn+ZnSO4·7H2O+MHx|PMA+APT|PbO2+V2O5+C+E gives an open circuit voltage of 1.5V and can run for >850h at a Current Drain of 2.4μA cm-2. The cell can be recharged without much loss up to 18-20cycles. © 2002 Published by Elsevier Science B.V.

Pulling the plug on the Current Drain [threshold switching]
IEEE Circuits and Devices Magazine, 2004Co-Authors: R.l. FranzAbstract:Power management is one of the main challenges to continued development of large-scale integrated circuits. In particular, the offstate, or standby leakage, is becoming a significant fraction of total power consumption as gate dimensions continue to shrink. A review of the literature identified many possible solutions in the application of threshold-switching devices. This data has apparently never been summarized in one place, suggesting a need for this article. This article discusses the capabilities of classical amorphous semiconductor switches, and more recent advances in silicon, III-V materials, and organic semiconductors that all exhibit threshold-switching properties. Applications and future prospects for the development of more energy-efficient devices are discussed. The long-term vision is that conductors themselves can be engineered to dynamically sense and adapt their conductivity to active or passive states as required.
