▎ 摘  要

SnS2 nanoflakes anchored three dimensional graphene foam (SnS2@GF) as flexible lithium ion battery anodes were fabricated via a single mode microwave hydrothermal technique. The flexible SnS2@GF electrode shows high capacity, high rate capability and long cycling life for lithium ion battery. The SnS2 @GF electrode exhibits a high reversible specific capacity 1386.7 mAh/g at 0.1 A/g and a long cycling life with a high capacity of 818.4 mAh/g after 500 cycles at 1 A/g. The excellent performance of flexible SnS2 @GF electrode is attributed to the reduced strain during intercalation/extraction process, shortened ion transport distance, higher conductivity and more electrode/electrolyte contact area.
