Abstract

An ultrathin sulfur layer (10 nm) wrapped polyaniline (PANI) nanofiber composite (S–PANI) with a core–shell structure was prepared via facile heterogeneous nucleation of sulfur on a water-dispersed PANI nanofiber, which displayed an initial discharge capacity of 977 mA h g⁻¹ and a capacity retention of 88.3% after 100 cycles at 1 C.
