  1. Liquid Catholyte Molecules for Nonaqueous Redox Flow Batteries

    Jinhua Huang, Lei Cheng, Rajeev S. Assary, Peiqi Wang, Zheng Xue, Anthony K. Burrell, Larry A. Curtiss and Lu Zhang

    Article first published online: 25 NOV 2014 | DOI: 10.1002/aenm.201401782

    A series of dimethoxybenzene-based catholyte molecules, which are electrochemically reversible at high potential (4.0 V vs Li/Li+) and in the form of liquid, is developed. The liquid nature offers the molecules the possibility of being a solo or co-solvent for nonaqueous redox flow batteries. This could dramatically improve the energy density.

  2. In Situ Investigations of Li-MoS2 with Planar Batteries

    Jiayu Wan, Wenzhong Bao, Yang Liu, Jiaqi Dai, Fei Shen, Lihui Zhou, Xinghan Cai, Daniel Urban, Yuanyuan Li, Katherine Jungjohann, Michael S. Fuhrer and Liangbing Hu

    Article first published online: 25 NOV 2014 | DOI: 10.1002/aenm.201401742

    A planar microbattery that enables various in situ measurements of lithiation of 2D materials on the individual-flake scale is developed. A large conductivity increase of thick MoS2 crystallite lithiation due to the formation of a percolative Mo nanoparticle network embedded in a Li2S matrix is observed. The nanoscale study leads to the development of a novel charging strategy for batteries that largely improves the capacity and cycling performance confirmed in bulk MoS2/Li coin cells.

  3. Novel Metal@Carbon Spheres Core–Shell Arrays by Controlled Self-Assembly of Carbon Nanospheres: A Stable and Flexible Supercapacitor Electrode

    Xinhui Xia, Yongqi Zhang, Zhanxi Fan, Dongliang Chao, Qinqin Xiong, Jiangping Tu, Hua Zhang and Hong Jin Fan

    Article first published online: 25 NOV 2014 | DOI: 10.1002/aenm.201401709

    An array of carbon nanospheres shows good supercapacitive properties. Carbon nanospheres (CNSs) are assembled onto a vertical-standing Ni microtube scaffold, forming a core–shell array structure. This new type of metal@CNSs array is demonstrated to be a highly stable and flexible electrode for supercapacitors. Symmetric supercapacitors have a capacitance retention of 97% after 40 000 cycles.

  4. Surface Cleaning and Passivation Using (NH4)2S Treatment for Cu(In,Ga)Se2 Solar Cells: A Safe Alternative to KCN

    Marie Buffière, Abdel-Aziz El Mel, Nick Lenaers, Guy Brammertz, Armin E. Zaghi, Marc Meuris and Jef Poortmans

    Article first published online: 25 NOV 2014 | DOI: 10.1002/aenm.201401689

    With the aim of improving the surface properties of the Cu(In,Ga)Se2 absorber, a chemical treatment process based on the immersion of the absorber into a S(NH4)2 solution is developed. This treatment results first in the removal of CuxSe secondary phase from the absorber surface and second in the incorporation of sulfur into the surface region of the material. Both of these effects can explain the improvement of open-circuit voltage and minority carrier lifetime in the resulting devices.

  5. Low-Temperature Fabrication of Efficient Wide-Bandgap Organolead Trihalide Perovskite Solar Cells

    Cheng Bi, Yongbo Yuan, Yanjun Fang and Jinsong Huang

    Article first published online: 25 NOV 2014 | DOI: 10.1002/aenm.201401616

    Thumbnail image of graphical abstract

    A mixed halide perovskite solar cell with a 1.72 eV bandgap is developed by incorporating Br into perovskite through a low-temperature solution process. A high efficiency of 13.1% is achieved by carefully tuning the thickness, morphology, and surface passivation of the perovskite layers. The fabrication techniques and conditions are compatible with future perovskite/Si tandem cell studies.
