Rational design of Co embedded N, S-codoped carbon nanoplates as anode materials for high performance lithium-ion batteries

Abstract

The construction of specific structures and heteroatom-doped nanomaterials is essential for enhancing electrochemical performance of lithium-ion batteries (LIBs). Herein, three structures of cobalt nanoparticles embedded N, S-codoped carbon (CNSCo-x) nanocomposites are obtained by pyrolysis of different amounts of thioacetamide (TAA) sulfuretted zeolitic imidazolate frameworks (ZIF-67) under Ar/H2 atmosphere. With addition of 0.5 mmol of TAA, CNSCo-0.5 with orderly and porous nanoplate structure is obtained. The CNSCo-0.5 exhibits the best rate behavior and cycling stability with an initial discharge capacity of 1355 mA h g-1 at 200 mA g-1, and high discharge capacities of 1360.4 mA h g-1 at 200th cycles at 200 mA g-1, 647.9 mA h·g-1 at 400th cycles at 1000 mA g-1. The facile synthetic strategy could be extended to other MOFs and is significant for developing new materials for LIBs.
