英文摘要	To improve electron transfer and ion diffusion for lithium ion batteries (LIBs) and sodium ion batteries (SIBs), multi-layered sandwich-like CuCo2S4/rGO architectures (MS-CuCo2S4/rGO) are fabricated, in which the inserted CuCo2S4 spheres are anchored on the surface of rGO tightly due to strong chemical bonding. The MS-CuCo2S4/rGO architectures exhibit impressive electrochemical performance as anodes for both LIBs and SIBs. They show a high and stable capacities of 792 mAh g(-1) at 500 mA g(-1) after 1000 cycles for LIBs and 344.5 mAh g(-1) at 1000 mA g(-1) after 800 cycles for SIBs, which are 5 and 3.5 times that of pure CuCo2S4 for LIBs and SIBs, respectively. The electrochemical results show about 77.8% and 68.4% charge contribution from capacitive-controlled capacity for LIBs and SIBs, leading to excellent electrochemical performance. The in-situ XRD tests also prove that a conversion-type sodium storage mechanism is beneficial to high capacity. Additionally, the successfully paired Na3V2(PO4)(3)parallel to MS-CuCo2S4/rGO full sodium ion cell displays a reversible capacity of 225 mAh g(-1) at 500 mA g(-1) after 100 cycles. These results will shed light on the practical application of MS-CuCo2S4/rGO as high-performance electrode with long-term cycling stability for next generation LIBs and SIBs. (C) 2020 Elsevier B.V.
