▎ 摘 要
Ce0.05SnS2/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 Ce0.05SnS2 particles with a petal size of 50-100 nm were distributed on graphene sheets. The Ce0.05SnS2/GNS(2) composites exhibited an initial discharge capacity of 1638.3 mAh g(-1) at 0.5 C, a retention capacity of 707 mAh g(-1) after 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.
