  1. Electrochemically Stable Rechargeable Lithium–Sulfur Batteries with a Microporous Carbon Nanofiber Filter for Polysulfide

    Sheng-Heng Chung, Pauline Han, Richa Singhal, Vibha Kalra and Arumugam Manthiram

    Article first published online: 3 JUL 2015 | DOI: 10.1002/aenm.201500738

    Various activated carbon nanofibers (ACNF) are adhered onto one side of a polypropylene membrane to form ACNF-filter-coated separators. Four different ACNF filters with tunable micropores are examined to optimize the polysulfide-trapping capability, enhance redox reversibility, and bolster mechanical durability. The results demonstrate that ACNF filters possessing abundant micropores and good electrical conductivity emphatically boost the overall Li–S cell performance.

    The evolution of the solid electrolyte interface (SEI) in carbon-coated ZnFe2O4 (ZFO-C) anodes is studied by soft X-ray absorption spectroscopy (XAS). Experiments probe locally the SEI growth in the 2–100 nm range, using both total electron (TEY) and total fluorescence (TFY) yield techniques. XAS analysis shows that the SEI grows preferentially around the ZFO-C nanoparticles.

  3. Superior Bifunctional Electrocatalytic Activity of Ba0.5Sr0.5Co0.8Fe0.2O3-δ/Carbon Composite Electrodes: Insight into the Local Electronic Structure

    Emiliana Fabbri, Maarten Nachtegaal, Xi Cheng and Thomas J. Schmidt

    Article first published online: 1 JUL 2015 | DOI: 10.1002/aenm.201402033

    Carbon acts as activity booster for Ba0.5Sr0.5Co0.8Fe0.2O3-δ for the oxygen reduction and evolution reaction due to the occurrence of electronic effects that change the local perovskite electronic configuration. The change of the Co oxidation state in Ba0.5Sr0.5Co0.8Fe0.2O3-δ when it is coupled with carbon can account for the superior catalytic activity composite electrodes versus single material electrodes.

  4. A Flexible Quasi-Solid-State Asymmetric Electrochemical Capacitor Based on Hierarchical Porous V2O5 Nanosheets on Carbon Nanofibers

    Linlin Li, Shengjie Peng, Hao Bin Wu, Le Yu, Srinivasan Madhavi and Xiong Wen (David) Lou

    Article first published online: 1 JUL 2015 | DOI: 10.1002/aenm.201500753

    An advanced free-standing film electrode is successfully fabricated by anchoring hierarchical porous V2O5 nanosheets on flexible electrospun carbon nanofibers. Utilizing this integrated electrode, a flexible quasi-solid-state hybrid supercapacitor is assembled and shown to manifest outstanding cycling stability, enhanced energy/power density, and excellent flexibility.

  5. Solid Solution Domains at Phase Transition Front of LixNi0.5Mn1.5O4

    Here the phase transition dynamics of LixNi0.5Mn1.5O4 is elucidated on high rate charging–discharging using operando time-resolved X-ray diffraction (TR-XRD). The TR-XRD results indicate the existence of intermediate states ascribed to the solid-solution domains at the phase transition front. The phase transition pathways dependent on the reaction rate are shown, together with possible explanation for this unique transition behavior.
