Abstract
Heteroatom-enrichedamorphouscarbonwithhierarchicalporousstructure(HAC-HPS)waspreparedfor use asanodematerialforLi-ionbatteries.ThepreparedHAC-HPShadopenmacroporousstructurewitha large numberofnanoporesandexhibitedahighspecific surfaceareaof1265.9m2/g. Inaddition,the preparedHAC-HPShadnumerousheteroatoms,with9.8at%oxygen,7.3at%nitrogen,and7.6at%sulfur. The HAC-HPSshowedsuperiorelectrochemicalperformance,includingahighreversiblecapacityof 935 mAh/g,goodrateperformance,andgreatcyclestabilityover275cycles.Thespecific capacity increased continuouslyandreached1090mAh/gbythe270thcycle.
