Abstract
- Transition metal organic framework materials and their selenides are considered to be one of the most promising cathode materials for nickel-zinc (denoted as Ni-Zn) batteries due to their low cost, environmental friendliness, and controllable microstructure. Yet, their low capacity and poor cycling performance severely restricts their further development. Herein, we developed a simple one-pot hydrothermal process to directly synthesize NiSe<subscript>2</subscript> (denotes as NiSe<subscript>2</subscript>-X based on the molar amount of SeO<subscript>2</subscript> added) stacked layered sheets. Benefiting from the peculiar architectures, the fabricated NiSe<subscript>2</subscript>−1//Zn battery based on NiSe<subscript>2</subscript> and the Zn plate exhibits a high specific capacity of 231.6 mAh g<superscript>−1</superscript> at 1 A g<superscript>−1</superscript>, and excellent rate performance (162.8 mAh g<superscript>−1</superscript> at 10 A g<superscript>−1</superscript>). In addition, the NiSe<subscript>2</subscript>//Zn battery also presents a satisfactory cycle life at the high current density of 8 A g<superscript>−1</superscript> (almost no decay compared to the initial specific capacity after 1000 cycles). Additionally, the battery device also exhibits a satisfactory energy density of 343.2 Wh kg<superscript>−1</superscript> and a peak power density of 11.7 kW kg<superscript>−1</superscript>. This work provides a simple attempt to design a high-performance layered cathode material for aqueous Ni-Zn batteries. [ABSTRACT FROM AUTHOR]
