摘要

Abstract

To address the low conductivity and easy agglomeration of transition metal sulfide nanoparticles

FeCoS

nanoparticles embedded in S-doped hollow carbon (FeCoS

@S-HC) composites were successfully fabricated through a combination of hydrothermal processes and sulfidation treatment. The unique bowlshaped FeCoS

/S-HC composites exhibit excellent structural stability with a high specific surface area of 303.7 m

·g

-1

and a pore volume of≥0.93 cm

·g

-1

. When applied as anode material for lithium-ion batteries

the FeCoS

@S-HC anode exhibits efficient lithium storage with high reversible specific capacity (970.2 mA·h·g

-1

at 100 mA·g

-1

) and enhanced cycling stability (574 mA·h·g

-1

at≥0.2 A·g

-1

after 350 cycles

a capacity retention of 84%). The excellent lithium storage is attributed to the fact that the bimetallic FeCoS

nanoparticles with abundant active sites can accelerate the electrochemical reaction kinetics

and the bowl-shaped S-HC structure can provide a stable mechanical structure to suppress volume expansion.
