摘要 | Sodium-ion batteries (SIBs) have been investigated as promising alternatives to lithium-ion batteries (LIBs) because of the rich sodium natural resource. Exploring suitable electrode materials is still a great challenge for the practical applications of SIBs. Herein, we demonstrate a novel three-dimensional porous carbon-coated graphene (3D PG@C) anode for SIBs using silica as the porous template combined with a subsequent polyaniline (PANI)-converted carbon coating. The synthesis process mainly consists of deposition of SiO2 nanoparticles on graphene surface, in situ polymerization of aniline monomers and carbonization of PANI and etching of SiO2. The resultant 3D PG@C composite possesses high electrical conductivity, rapid ion insertion, sufficient active sites, short ionic diffusion distance and stable structural integrity for efficient Na-storage. As an anode material for SIBs, the 3D PG@C composite delivers excellent Na-storage performance, in terms of high initial discharge capacity (824 mAh g(-1) at 50 mA g(-1)), large reversible capacity and long cyclability (323 mAh g(-1) after 1000 cycles at 1000 mA g(-1)) and remarkable rate capability (207 mAh g(-1) at 10000 mA g(-1)). The design strategy reported in this work would provide a promising approach toward high-stable and long-life carbonaceous anode materials for SIBs. (C) 2017 Elsevier B.V. All rights reserved. |
