| 英文摘要 | the introduction of a secondary phase is an efficient and effective way to improve the electrochemical performance of graphene towards energy storage applications. two fundamental strategies including pre-graphenization and post-graphenization were widely employed for graphene-based hybrids. however, there is still an open question of which way is better. in this contribution, we investigated the differences in the structure and electrochemical properties of pre- and post-graphenized graphene-sno2 hybrids. the pre-graphenization is realized by synthesis of thermally reduced graphene and subsequent impregnation of sno2, while the post-graphenization is realized by introducing a sn-containing phase onto go sheets followed by chemical reduction. the pre-graphenization process provides a large amount of pores for ion diffusion, which is of benefit for loading of sno2, fast ion diffusion for supercapacitors, and higher capacity for li-ion batteries, but poor stability, while the post-graphenization process offers compact graphene and good interaction between the sno2 and graphene, which provides stable structure for long term stability for supercapacitor and li-ion battery use. |
