  1. A High Areal Capacity Flexible Lithium-Ion Battery with a Strain-Compliant Design

    Abhinav M. Gaikwad, Brian V. Khau, Greg Davies, Benjamin Hertzberg, Daniel A. Steingart and Ana Claudia Arias

    Article first published online: 23 SEP 2014 | DOI: 10.1002/aenm.201401389

    Flexible lithium-ion batteries with a high areal capacity of ≈1 mAh cm-2 and an open-circuit potential of 2.6 V are demonstrated. Due to the reinforced electrode design, the batteries are able to maintain their capacity, even after repeated flexing up to a bend radius of 10 mm.

  2. Integrated Design of Organic Hole Transport Materials for Efficient Solid-State Dye-Sensitized Solar Cells

    Bo Xu, Haining Tian, Lili Lin, Deping Qian, Hong Chen, Jinbao Zhang, Nick Vlachopoulos, Gerrit Boschloo, Yi Luo, Fengling Zhang, Anders Hagfeldt and Licheng Sun

    A series of triphenylamine-based small molecular hole transport materials (HTMs) are systematically investigated in solid-state dye-sensitized solar cell (ssDSCs). Among these HTMs, X3- and X35-based devices exhibit desirable power conversion efficiencies of 5.8% and 5.5%, which are better than those for the device using the state-of-the-art Spiro-OMeTAD (5.4%). This makes these new HTMs promising for high-efficiency ssDSCs or perovskite solar cells.

  3. Optimization of Carbon- and Binder-Free Au Nanoparticle-Coated Ni Nanowire Electrodes for Lithium-Oxygen Batteries

    Sun Tai Kim, Nam-Soon Choi, Soojin Park and Jaephil Cho

    Article first published online: 22 SEP 2014 | DOI: 10.1002/aenm.201401030

    Au nanoparticle-coated Ni nanowire substrates are used as the electrode (Au/Ni electrode) for Li-O2 batteries. This optimized Au/Ni electrode demonstrates improved capacity of ≈600 mAh g−1Au. More importantly, it exhibits improved cyclability over 200 cycles at full discharge and charge conditions between 2.3 and 4.3 V.

  4. Electrochemical Design of Nanostructured ZnO Charge Carrier Layers for Efficient Solid-State Perovskite-Sensitized Solar Cells

    Jie Zhang, Philippe Barboux and Thierry Pauporté

    Article first published online: 22 SEP 2014 | DOI: 10.1002/aenm.201400932

    Efficient perovskite-sensitized solar cells are prepared based on designed electrodeposited zinc oxide scaffold layers. They combine Cl-doped vertically oriented nanowire arrays and an intermediate thin overlayer of low n-type doped ZnO. Very large photocurrents and open-circuit voltages are achieved and a power conversion efficiency as high as 10.28% is demonstrated.

  5. Direct Observation of Ordered Oxygen Defects on the Atomic Scale in Li2O2 for Li-O2 Batteries

    Dongdong Xiao, Shanmu Dong, Jing Guan, Lin Gu, Shanming Li, Nijie Zhao, Chaoqun Shang, Zhenzhong Yang, Hao Zheng, Chun Chen, Ruijuan Xiao, Yong-Sheng Hu, Hong Li, Guanglei Cui and Liquan Chen

    Article first published online: 22 SEP 2014 | DOI: 10.1002/aenm.201400664

    The structure of the discharge product, Li2O2, in lithium-oxygen batteries is revealed directly on the atomic scale. A unique stage ordering that the peroxide vacancy occupies preferentially in every other layer along the c-axis of Li2O2 is observed. This finding provides new insight into the relationship between the structure of Li2O2 and the discharge/charge behavior of Li-O2 batteries.
