原始语种摘要: Abstract(#br)Tin selenide (SnSe) shows great potential as a promising anodic candidate of commercial graphite in Li-ion batteries (LIBs), but its practical application is hampered by huge volume change-induced poor cycle span. Herein, a gel-enabled selenization route has been developed for uniformly confining SnSe nanobelts within reduced graphene oxide aerogel (SnSe NB@rGO framework). These unique structural and compositional features make the SnSe NB@rGO framework electrode to show high revisable capacities (620 mA h g −1 after 200 cycles at 0.1 A g −1 ), high rate capability (626 and 551 mA h g −1 at 0.5 and 1 A g −1 , respectively) and ultralong cycle span (412 mA h g −1 after 800 cycles at 1 A g −1 ).
