SnO<sub>2</sub> has been extensively studied as an anode material
for sodium-ion batteries, which, however, has long been subjected
to poor conductivity and large volume expansion accompanied with an
unsatisfactory electrochemical performance. 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.
