Abstract
- The construction of specific structures and heteroatom-doped nanomaterials is essential for enhancing the electrochemical performance of lithium-ion batteries (LIBs). Herein, three structures of cobalt nanoparticle 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 an Ar/H<subscript>2</subscript> atmosphere. With the addition of 0.5 mmol of TAA, CNSCo-0.5 with an 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<superscript>−1</superscript> at 200 mA g<superscript>−1</superscript>, and high discharge capacities of 1360.4 mA h g<superscript>−1</superscript> at the 200<superscript>th</superscript> cycle at 200 mA g<superscript>−1</superscript>, and 647.9 mA h·g<superscript>−1</superscript> at the 400<superscript>th</superscript> cycle at 1000 mA g<superscript>−1</superscript>. This facile synthetic strategy could be extended to other MOFs and is significant for developing new materials for LIBs. [ABSTRACT FROM AUTHOR]
