A Review of Functional Binders in Lithium–Sulfur Batteries
Advanced Energy Materials - Tập 8 Số 31 - 2018
Hong Yuan, Jia‐Qi Huang, Hong‐Jie Peng, Maria‐Magdalena Titirici, Rong Xiang, Renjie Chen, Quanbing Liu, Qiang Zhang
AbstractLithium–sulfur (Li–S) batteries have received tremendous attention due to their superior theoretical energy density of 2600 Wh kg−1, as well as the abundance of sulfur resources and its environmental friendliness. Polymer binders as an indispensable component in cathodes play a critical role in maintaining the structural integrity and s...... hiện toàn bộ
Carbon Quantum Dots–Modified Interfacial Interactions and Ion Conductivity for Enhanced High Current Density Performance in Lithium–Sulfur Batteries

AbstractSignificant progress has achieved for developing lithium–sulfur (Li–S) batteries with high specific capacities and excellent cyclic stability. However, some critical issues emerge when attempts are made to raise the areal sulfur loading and increase the operation current density to meet the standards for various industrial applications. In this work, polyet...... hiện toàn bộ
New Acetylene‐Bridged 9,10‐Conjugated Anthracene Sensitizers: Application in Outdoor and Indoor Dye‐Sensitized Solar Cells
Advanced Energy Materials - Tập 7 Số 18 - 2017
Yogesh S. Tingare, Vinh Sơn Nguyễn, Hsien‐Hsin Chou, Yu‐Chieh Liu, Yean‐San Long, Teng‐Chun Wu, Tzu‐Chien Wei, Chen‐Yu Yeh
In this report, a pivotal improvement in the performance of dye‐sensitized solar cells has been achieved, thus taking it one step closer toward the commercialization. Through the stepwise modification on the anthracene‐based organic sensitizers, the alteration of alkyl to alkoxy chain and incorporation of electron deficient moieties in the new sensitizing dyes TY3, <...... hiện toàn bộ
Rational Design of Coating Ions via Advantageous Surface Reconstruction in High‐Nickel Layered Oxide Cathodes for Lithium‐Ion Batteries
Advanced Energy Materials - Tập 11 Số 38 - 2021
Youngjin Kim, Hyoju Park, Kihyun Shin, Graeme Henkelman, Jamie H. Warner, Arumugam Manthiram
AbstractThe implementation of high‐nickel layered oxide cathodes in lithium‐ion batteries is hampered by the inherent issues of formation of NiO‐like rock‐salt phase as well as residual lithium (e.g., LiOH, LiHCO3, and Li2CO3) on the surface. To overcome the challenges, here a rational strategy is prese...... hiện toàn bộ
Hierarchical Nanostructures: Design for Sustainable Water Splitting
Advanced Energy Materials - Tập 7 Số 23 - 2017
Ming Fang, Guofa Dong, Renjie Wei, Johnny C. Ho
AbstractClean and sustainable hydrogen generation renders a magnificent prospect to fulfill the humans' dream of rebuilding energy supplying systems that work eternally and run without pollution. Water electrolysis driven by a renewable resource of energy, such as wind and solar, is a promising pathway to achieve this goal, which requires highly active and cost‐eff...... hiện toàn bộ
Exceptional Visible‐Light‐Driven Cocatalyst‐Free Photocatalytic Activity of g‐C3N4 by Well Designed Nanocomposites with Plasmonic Au and SnO2
Advanced Energy Materials - Tập 6 Số 21 - 2016
Amir Zada, Muhammad Humayun, Fazal Raziq, Xuliang Zhang, Yang Qu, Linlu Bai, Chuanli Qin, Liqiang Jing, Honggang Fu
In this work, plasmonic Au/SnO2/g‐C3N4 (Au/SO/CN) nanocomposites have been successfully synthesized and applied in the H2 evolution as photocatalysts, which exhibit superior photocatalytic activities and favorable stability without any cocatalyst under visible‐light irradiation. The amount‐optimized 2Au/6SO...... hiện toàn bộ
A High Performance Stretchable Asymmetric Fiber‐Shaped Supercapacitor with a Core‐Sheath Helical Structure
Advanced Energy Materials - Tập 7 Số 3 - 2017
Jiali Yu, Weibang Lu, Joseph P. Smith, Karl S. Booksh, Meng Ling, Yudong Huang, Qingwen Li, Joon‐Hyung Byun, Youngseok Oh, Yushan Yan, Tsu‐Wei Chou
The emerging fiber‐shaped supercapacitors (FSSs) have motivated tremendous research interest in energy storage devices. However, challenges still exist in the pursuit of combination of excellent electrochemical performance and mechanical stretchability. Here, a core‐sheath asymmetric FSS is first made by wrapping gel electrolyte coated carbon nanotube (CNT)@MnO2 core f...... hiện toàn bộ
Optimum Carrier Concentration in n‐Type PbTe Thermoelectrics
Advanced Energy Materials - Tập 4 Số 13 - 2014
Yanzhong Pei, Zachary M. Gibbs, A. Gloskovskii, Benjamin Balke, Wolfgang G. Zeier, G. Jeffrey Snyder
Taking La‐ and I‐doped PbTe as an example, the current work shows the effects of optimizing the thermoelectric figure of merit, zT, by controlling the doping level. The high doping effectiveness allows the carrier concentration to be precisely designed and prepared to control the Fermi level. In addition to the Fermi energy tuning, La‐doping modifies the conducti...... hiện toàn bộ
