Unraveling the energy storage mechanism in graphene-based nonaqueous electrochemical capacitors by gap-enhanced Raman spectroscopy

Autor: Xiao-Ting Yin, En-Ming You, Ru-Yu Zhou, Li-Hong Zhu, Wei-Wei Wang, Kai-Xuan Li, De-Yin Wu, Yu Gu, Jian-Feng Li, Bing-Wei Mao, Jia-Wei Yan

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-12 (2024)

Abstract Graphene has been extensively utilized as an electrode material for nonaqueous electrochemical capacitors. However, a comprehensive understanding of the charging mechanism and ion arrangement at the graphene/electrolyte interface remain elus

Resolving nanostructure and chemistry of solid-electrolyte interphase on lithium anodes by depth-sensitive plasmon-enhanced Raman spectroscopy

Publikováno v: Nature Communications, Vol 14, Iss 1, Pp 1-11 (2023)

Abstract The solid-electrolyte interphase (SEI) plays crucial roles for the reversible operation of lithium metal batteries. However, fundamental understanding of the mechanisms of SEI formation and evolution is still limited. Herein, we develop a de

Promoting electrocatalytic CO2 reduction to formate via sulfur-boosting water activation on indium surfaces

Autor: Wenchao Ma, Shunji Xie, Xia-Guang Zhang, Fanfei Sun, Jincan Kang, Zheng Jiang, Qinghong Zhang, De-Yin Wu, Ye Wang

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-10 (2019)

CO2 conversion to liquid fuels provides an appealing means to remove the greenhouse gas, although it is challenging to find materials that are both active and selective. Here, authors show sulfur-doped indium to be a highly active and selective elect

Designable ultra-smooth ultra-thin solid-electrolyte interphases of three alkali metal anodes

Autor: Yu Gu, Wei-Wei Wang, Yi-Juan Li, Qi-Hui Wu, Shuai Tang, Jia-Wei Yan, Ming-Sen Zheng, De-Yin Wu, Chun-Hai Fan, Wei-Qiang Hu, Zhao-Bin Chen, Yuan Fang, Qing-Hong Zhang, Quan-Feng Dong, Bing-Wei Mao

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-9 (2018)

The dendrite growth of alkali metal anodes leads to charge/discharge cycling instability. Here, the authors show that electrochemical polishing can yield near-perfect anodes of three alkali metals by constructing smooth and thin solid-electrolyte int

Anion-Binding-Induced Electrochemical Signal Transduction in Ferrocenylimidazolium: Combined Electrochemical Experimental and Theoretical Investigation

Autor: Tan-Qing Weng, Yi-Fan Huang, Lou-Sha Xue, Jie Cheng, Shan Jin, Sheng-Hua Liu, De-Yin Wu, George Z. Chen

Publikováno v: Molecules, Vol 24, Iss 2, p 238 (2019)

Five ferrocene alkymethylimidazolium cations 1a–1d and 2 with different alkyl spacer lengths were reinvestigated using voltammetry and density functional theory (DFT) calculations. The voltammetric responses of ligand 2 toward various anions are de
