Abstract
- The demand for large-scale and safe energy storage is increasing rapidly due to the strong push for smartphones and electric vehicles. As a result, Li<superscript>+</superscript>/Mg<superscript>2+</superscript> hybrid-ion batteries (LMIBs) combining a dendrite-free deposition of Mg anode and Li<superscript>+</superscript> intercalation cathode have attracted considerable attention. Here, a LMIB with hydrothermal-prepared MoS<subscript>2</subscript> nano flowers as cathode material was prepared. The battery showed remarkable electrochemical properties with a large discharge capacity (243 mAh g<superscript>−1</superscript> at the 0.1 C rate), excellent rate capability (108 mAh g<superscript>−1</superscript> at the 5 C rate), and long cycle life (87.2 % capacity retention after 2300 cycles). Electrochemical analysis showed that the reactions occurring in the battery cell involved Mg stripping/plating at the anode side and Li<superscript>+</superscript> intercalation at the cathode side with a small contribution from Mg<superscript>2+</superscript> adsorption. The excellent electrochemical performance and extremely safe cell system show promise for its use in practical applications. [ABSTRACT FROM AUTHOR]
