Here, novel interlaced SnO<sub>2</sub> 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 SnO<sub>2</sub>@PPy on the carbon cloth exhibits a high initial capacity of 1172.1 mAh g<sup>–1</sup> and an outstanding cycling stability with 85% capacity retention after 300 cycles at 0.1 A g<sup>–1</sup>, which can be contributed to the interlaced SnO<sub>2</sub> nanoflakes as well as the coating of PPy. This result shows promising potential for construction of an electrode in high-performance energy storage fields.
