Here, novel interlaced SnO2 nanoflakes are synthesized directly on a carbon cloth collector via hydrothermal and annealing treatment and then coated with polypyrrole (PPy) via electrodeposition. The as-prepared flexible SnO2@PPy on the carbon cloth exhibits a high initial capacity of 1172.1 mAh g–1 and an outstanding cycling stability with 85% capacity retention after 300 cycles at 0.1 A g–1, which can be contributed to the interlaced SnO2 nanoflakes as well as the coating of PPy. This result shows promising potential for construction of an electrode in high-performance energy storage fields. %I ACS Publications
