1Sn-O dual-doped Li-argyrodite electrolytes with enhanced electrochemical performance显示文摘As a type of candidate for all-solid-state Li batteries,argyrodite solid electrolytes possess high ionic conductivity,but poor compatibility against Li metal.Here,we report novel Li_(6) PS_(5) I-based argyrodite sulfides with Sn-O dual doping,which is a powerful solution to comprehensively improve the performance of a material.The combination of O and Sn-aliovalent doping not only enables an improved ionic conductivity but more importantly realizes an intensively enhanced interfacial compatibility between argyrodite and Li metal and Li dendrite suppression capability.The assembled battery with Sn-O dual-doped electrolyte and Li anode demonstrates high capacity and decent cycling stability.Dual doping is thus believed to be an effective way to develop high performance sulfide solid electrolytes.Ting Chen Dewu Zeng Long Zhang Meng Yang Dawei Song Xinlin Yan Chuang Yu 2021Journal of Energy Chemistry2021,30,8:1

3Laser photolysis of ionic liquid [bmim][PF_6]显示文摘Photoinduced chemical reactions of 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF_6]) were studied by laser photolysis at a wavelength of 266 nm.Excited triplet state ~3[bmim]^+ was observed,radical cation [bmim]^(2+) and neutral [bmim] radical via photoionization were also formed.Energy transfer from ~3[bmim]^+ toβ-carotene was confirmed.Oxidation via one electron transfer from TMPD to ~3[bmim]^+ was also observed and the rate constant was determined to be 1.2×10.5 L.mol^(-1).s^(-1).The reaction of [bmim][PF_6] with hydrated electron (e_(aq)) was confirmed by laser photolysis in aqueous solution.ZHU Guanglai WU Guozhong LONG Dewu YAO Side 2007Nuclear Science and Techniques2007,18,1:0
