| الوصف: | Lithium sulfide (Li2S) is a promising cathode material for LiS batteries with high capacity (theoretically 1166 mAh g(1)) and can be paired with nonlithiummetal anodes to avoid potential safety issues. However, the cycle life of coarse Li2S particles suffers from poor electronic conductivity and polysulfide shuttling. Here, we develop a flexible slurryless nano-Li2S/reduced graphene oxide cathode paper (nano-Li2S/rGO paper) by simple drop-coating. The Li2S/rGO paper can be directly used as a free-standing and binder-free cathode without metal substrate, which leads to significant weight savings. It shows excellent rate capability (up to 7 degrees C) and cycle life in coin cell tests due to the high electron conductivity, flexibility, and strong solvent absorbency of rGO paper. The Li2S particles that precipitate out of the solvent on rGO have diameters 2550 nm, which is in contrast to the 35 mu m coarse Li2S particles without rGO. ; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000351188000054&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Test ; Chemistry, Multidisciplinary ; Chemistry, Physical ; Nanoscience & Nanotechnology ; Materials Science, Multidisciplinary ; Physics, Applied ; Physics, Condensed Matter ; SCI(E) ; EI ; PubMed ; 29 ; ARTICLE ; chenjitao@pku.edu.cn; huangyh@mail.hust.edu.cn; liju@mit.edu ; 3 ; 1796-1802 ; 15 |
