Abstract

Ce_0.05SnS₂/graphene (GNS) nanocomposites were synthesised via the hydrothermal method and sintering. The structure and electrochemical performance of the materials were characterised using X-ray diffraction, field emission transmission electron microscopy and electrochemical measurements. The flower-like Ce_0.05SnS₂particles with a petal size of 50-100 nm were distributed on graphene sheets. The Ce_0.05SnS₂/GNS- 2 composites exhibited an initial discharge capacity of 1638.3 mAh g^-1at 0.5 C, a retention capacity of 707 mAh g^-1after 50 cycles, and an improved rate capability because of the support of the nanographene. After their sintering, the Ce0.05SnS2/GNS nanocomposites displayed better electrochemical performance than before sintering.
