MOF derived hollow cage Ni Co mixed oxide/CNTs nanocomposites with enhanced electrochemical performance for lithium sulfur batteries
Reasonable design of the cathode host material can effectively improve the electrochemical performance of lithium sulfur batteries. In this work, a metal organic framework (MOF) based strategy was used to synthesize nanocomposites containing carbon nanotubes and nickel cobalt mixed metal oxide (denoted as Ni Co oxide/CNTs) The Ni Co oxide/CNTs/S cathode exhibits excellent electrochemical performance, the high discharge capacity of 1421.7 mAh g 1 at 0.1 C. This means that the porous Ni Co oxide interacts well with excellent conductivity CNTs to improve battery performance; indicate that the Ni Co oxide/CNTs /S is a potential host for the high capacity and cyclic stability lithium sulfur batteries.
