英文摘要	Being simple, inexpensive, scalable and environmentally friendly, microporous biomass biochars have been attracting enthusiastic attention for application in lithium-sulfur (Li-S) batteries. Herein, porous bamboo biochar is activated via a KOH/annealing process that creates a microporous structure, boosts surface area and enhances electronic conductivity. The treated sample is used to encapsulate sulfur to prepare a microporous bamboo carbon-sulfur (BC-S) nanocomposite for use as the cathode for Li-S batteries for the first time. The BC-S nanocomposite with 50 wt.% sulfur content delivers a high initial capacity of 1,295 mA center dot h/g at a low discharge rate of 160 mA/g and high capacity retention of 550 mA center dot h/g after 150 cycles at a high discharge rate of 800 mA/g with excellent coulombic efficiency (a (c) 3/495%). This suggests that the BC-S nanocomposite could be a promising cathode material for Li-S batteries.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000348200300009&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Chemistry, Physical; Nanoscience & Nanotechnology; Materials Science, Multidisciplinary; Physics, Applied; SCI(E); 中国科学引文数据库(CSCD); 43; ARTICLE; hou@pku.edu.cn; s.zhang@griffith.edu.au; 1; 129-139; 8
