Impurity intermediate band by Pb-doping induced promising thermoelectric performance of Ca5In2Sb6

20-May-2015 | Zhenzhen Feng; Yuanxu WANG; Yuli Yan; Guangbaio Zhang; jueming yang; Jihua Zhang; Chao Wang, Physical Chemistry Chemical Physics, 2015

Band engineering is one of effective approaches for designing ideal thermoelectric materials. Introducing an intermediate band in the band gap of semiconducting thermoelectric compounds may largely increase their carrier concentration and improve their electrical conductivity. We perform this ...

First-Principles Studies on Cation Dopants and Electrolyte|Cathode Interphases for Lithium Garnets

15-May-2015 | Lincoln J. Miara; William Davidson Richards; Yan E. Wang; Gerbrand Ceder, Chemistry of Materials, 2015

Lithium garnet with the formula Li7La3Zr2O12 (LLZO) has many properties of an ideal electrolyte in all-solid state lithium batteries. However, internal resistance in batteries utilizing these electrolytes remains high. For widespread adoption, the LLZO’s internal resistance must be lowered by ...

Mo-doped TiNb2O7 anode for lithium-ion batteries with high rate capability due to charge redistribution

14-May-2015 | Hannah Song; Yong-Tae Kim, Chemical Communication, 2015

Mo-doped TiNb2O7 (TNO) anode material has shown excellent electrochemical performance especially at high C-rates. Doping of TNO with Mo6+ resulted in charge redistribution leading to the enhancement of electronic conductivity (caused by band gap narrowing) and Li+ diffusivity in the lattice.

Capacitive Deionization using Biomass‐based Microporous Salt‐Templated Heteroatom‐Doped Carbons

13-May-2015 | Slawomir Porada, Florian Schipper, Mesut Aslan, Markus Antonietti, Volker Presser, Tim‐Patrick Fellinger, ChemSusChem, 2015

Abstract Microporous carbons are an interesting material for electrochemical applications. In this study, we evaluate several such carbons without/with N or S doping with regard to capacitive deionization. For this purpose, we extent the salt‐templating synthesis towards biomass precursors and ...

Doping Effect on Catalytic Activity of Graphene for Oxygen Evolution Reaction in Lithium−Air Battery: A First-Principles Study

13-May-2015 | Xiaodong Ren; Beizhou Wang; Jinzhen Zhu; Jianjun Liu; Wenqing Zhang; Zhaoyin Wen, Physical Chemistry Chemical Physics, 2015

The Lithium−air battery as an energy storage technology can be used in electric vehicle due to its large energy density. However, its poor rate capability, low power density and large overpotential problems limit its practical usage. In this paper, the first-principles thermodynamic calculations ...

2H-CuScO2 Prepared by Low-Temperature Hydrothermal Methods and Post-Annealing Effects on Optical and Photoelectrochemical Properties

13-May-2015 | Thomas I. Draskovic; Mingzhe Yu; Yiying Wu, Inorganic Chemistry, 2015

The delafossite structured CuScO2 is a p-type, wide band gap oxide that has been shown to support significant oxygen intercalation, leading to darkened color and increased conductivity. Control of this oxidation proves difficult by the conventional high-temperature solid-state syntheses. In ...
