英文摘要Sodium ion batteries (SIBs) for large-scale grid applications are facing great challenges in terms of development of high-performance electrode materials and screening of suitable electrolytes. Herein, a versatile and scalable protocol for synthesizing two-dimensional (2D) holey cobalt sulfide (h-Co4S3) nanosheets is demonstrated for high-rate and long-life SIBs in an ether-based electrolyte of 1.0 M NaCF3SO3 in diglyme. The 2D h-Co4S3 nanosheets are prepared by sulfuration of leaf-like cobalt based metal-organic frameworks (CoMOFs), and subsequent annealing treatment. Benefiting from the nanosheet nature of in-plane nanopores (10-30 nm), ultra-thinness (< 30 nm), crumpled morphology, and micron-scale lateral size that can provide more active sites and enhanced sodiation/desodiation kinetics, the resulting h-Co4S3 nanosheets achieve a high reversible capacity of 571 mA h g(-1) at 0.1 A g(-1), and long-life cycling stability with a retention of 80% after 400 cycles for SIBs. Furthermore, theoretical simulation reveals the enhanced structural stability of h-Co4S3 nanosheets with a lower binding energy (0.31 eV) of the Co-O bond in the ether-based electrolyte than that in the carbonate-based electrolyte. Notably, the h-Co4S3 anode offers an exceptional rate capacity of 257 mA h g(-1) at 12 A g(-1), outperforming most reported cobalt sulfide-based anodes. This strategy will pave a new way to rationally construct MOF-derived 2D nanostructures for various energy-related applications.
