Sb nanoparticles uniformly dispersed in 1-D N-doped porous carbon as anodes for Li-ion and Na-ion batteries

Abstract

The Sb nanoparticles encapsulated in 1-D N-doped porous carbon (denoted as Sb/NPC) have been fabricated by an in-situ nanoconfined replacement reaction between SbCl3 and the intermediats Ni/NPC, in which Ni/NPC was obtained by annealing the hydrothermally synthesized nickel-nitrilotriacetic acid (Ni-NTA) precursor in an argon atmosphere. The Sb nanoparticles with a size of 10-20 nm were uniformly encapsulated in the 1-D N-doped porous carbon scaffolds. When the Sb/NPC composite was applied as anode materials in the batteries, it exhibited a high reversible capacity of 556 mAh g-1 at 200 mA g-1 after 100 cycles for Li-ion batteries (LIB) and a reversible capacity of 400.9 mAh g-1 at 100 mA g-1 after 100 cycles for Na-ion batteries (NIB). Such enhanced electrochemical performance of the designed Sb/NPC can be attributed to the synergistic effect between uniformly dispersed Sb nanoparticles and the 1-D N-doped porous carbon matrixes.
