SnO sub(2)/Graphene Composites with Self-Assembled Alternating Oxide and Amine Layers for High Li-Storage and Excellent Stability

An alternating stack (SG/GN) consisting of SnO sub(2)-functionalized graphene oxide (SG) and amine-functionalized GO (GN) is prepared in solution. The thermally reduced SG/GN (r(SG/GN)) with decreased micro-mesopores and completely eliminated macropores, results in a high reversible capacity and exc...

Zusammenfassung:An alternating stack (SG/GN) consisting of SnO sub(2)-functionalized graphene oxide (SG) and amine-functionalized GO (GN) is prepared in solution. The thermally reduced SG/GN (r(SG/GN)) with decreased micro-mesopores and completely eliminated macropores, results in a high reversible capacity and excellent capacity retention (872 mA h g super(-1) after 200 cycles at 100 mA g super(-1)) when compared to a composite without GN.
