Abstract

Abstract: A spinel phase structure of MnIn2 S4 (MIS) as an anode material is prepared through a facile hydrothermal process for Li-ion batteries (LIBs). The improvement in electrochemical performance of Li-ion storage is achieved by encapsulating reduced graphene oxide (RGO) in the MIS as like MIS/RGO nanocomposite anode. The electrochemical performance of RGO and MIS composition is optimized. The optimized 10 wt% MIS/RGO (MIS-10) nanocomposite anode delivers a reversible capacity of 1256 mAh/g at 100 mA/g and showed an excellent cyclic stability of 679 mAh/g over 100 cycles at 200 mA/g. The dramatic enhancements in electrochemical performance of MIS/RGO are due to RGO's advantages in terms of its high conductivity, excellent flexibility, and high specific surface area. The electrochemical reaction mechanism of the MIS anode is investigated by in - situ XRD measurements. Overall, the results demonstrate that MIS/RGO is a potential novel anode candidate for high-performance LIBs and other ion-storage applications. Graphical abstract: Image 1 Highlights: MnIn2 S4 (MIS) material is synthesized as anode material for Li-ion batteries. Li-ion storage is optimized via different ratio of RGO in MIS as nanocomposite. The 10 wt.% RGO encapsulated MIS (MIS-10) shows better electrochemical performance. MIS-10 delivers a reversible capacity of 679 mAh/g over 100 cycles at 0.2 A/g. The electrochemical reaction mechanism of MIS is predicted by in-situ XRD and cyclic voltammogram tests.
