Pulsed laser deposition of a carbon thin film is used which dynamically removes the native surface oxide to form the desired Schottky interface. The combined device action yields two orders of magnitude photoresponse at zero bias.1 aShaikh, P., A.1 aThakare, V., P.1 aLate, D., J.1 aOgale, S. uhttps://library.ncl.res.in/content/back-back-mos%E2%80%93schottky-pt%E2%80%93sio2%E2%80%93si%E2%80%93c%E2%80%93pt-nano-heterojunction-device-efficient-self-powered01762nas a2200217 4500008004100000022001400041245012500055210006900180260000800249300001200257490000700269520102600276100001701302700002001319700001801339700001401357700001701371700001601388700001401404856012601418 2017 eng d a0025-540800aCuCo2O4 nanowall morphology as Li-ion battery anode: Enhancing electrochemical performance through stoichiometry control0 aCuCo2O4 nanowall morphology as Liion battery anode Enhancing ele cJUN a303-3100 v903 a

We have employed template-free synthesis of CuCo2O4 (CCO) system to achieve unique ultrathin porous nanowall type morphology, and evaluated for Li-Ion battery anode application. We observe that under the hydrothermal growth a starting stoichiometric mixture of cationic precursor's leads to a bi-phasic constitution comprising of defect-spinel CCO and a small quantity of CuO. Use of the excess but optimum cobalt in the precursor mix leads to single phase defect-spinel. We have carefully examined the implications of off-stoichiometry for different cases of interest (including the case of Cu-excess) for morphology, microstructure, the physical/electrochemical properties, and the evolution of the Li-ion battery anode under cycling for different active materials loading. In case of optimum Cu excess based CCO renders an impressive performance as Li-ion battery anode with high rate performance, 836 mAh g−1 and 757 mAh g−1 at 1.25C and 2.5C, respectively, and good cycling stability. © 2016 Elsevier Ltd

Abstract Image

Efficient Na ion intercalation/deintercalation in the semigraphitic lattice of a hard carbon derived from the walnut shell is demonstrated. High-temperature (1000 °C) pyrolysis of walnut shells under an inert atmosphere yields a hard carbon with a low surface area (59 m2 g–1) and a large interplanar c axis separation of 0.39–0.36 nm as compared to 0.32 nm for graphite, suitable for Na ion intercalation/deintercalation. A stable reversible capacity of 257 mAh g–1 is observed at a current density of 50 mA g–1 for such nutshell-derived carbon (NDC) with an impressive rate performance. No loss of electrochemical performance is observed for high current cycling (100 mA g–1 → 2 A g–1 → 100 mA g–1). Additionally, the NDC shows remarkably stable electrochemical performance up to 300 charge–discharge cycles at 100 mA g–1 with a minimal drop in capacity.
