Electrochemical exfoliation of molybdenum disulfide nanosheets for high-performance supercapacitors
Abstract Two-dimensional (2D) molybdenum disulfide ($ MoS_{2} $) nanomaterials have emerged as promising candidates for constructing excellent supercapacitors, but the lack of large-scale, efficient and low-cost methods for preparing $ MoS_{2} $ nanosheets severely hinders its practical application....

| 520 | |a Abstract Two-dimensional (2D) molybdenum disulfide ($ MoS_{2} $) nanomaterials have emerged as promising candidates for constructing excellent supercapacitors, but the lack of large-scale, efficient and low-cost methods for preparing $ MoS_{2} $ nanosheets severely hinders its practical application. This study demonstrates an accessible and efficient approach for electrochemical exfoliating bulk $ MoS_{2} $ into high-quality $ MoS_{2} $ nanosheets with size distribution in the range of 1–3 μm and a thickness of several nanometers in an easily available inorganic salt solution. Furthermore, we construct symmetric all-solid-state supercapacitors based on exfoliated $ MoS_{2} $ nanosheets. The 2D structure will provide stable channels to facilitate the intercalation/desorption of ions during charge and discharge, and to a certain extent can prevent deposition and agglomeration. Therefore, compared with the unexfoliated $ MoS_{2} $, as-prepared $ MoS_{2} $ nanosheets show great improvement in supercapacitor performance (the specific capacitance increases from the original 130 F $ g^{−1} $ to 215 F $ g^{−1} $ at 5 A $ g^{−1} $, for instance). In detail, the electrode possesses a specific capacitance of 285 F $ g^{−1} $ at a current density of 2 A $ g^{−1} $ and maintains the great capacitance retention of 83.8% at 8 A $ g^{−1} $. Moreover, the supercapacitor exhibits a high energy density of 136.8 Wh $ kg^{−1} $ at a power density of 2550 Wh $ kg^{−1} $. This work provides basic research on the preparation of 2D nanomaterials by electrochemical exfoliation. | ||

Electrochemical exfoliation of molybdenum disulfide nanosheets for high-performance supercapacitors |
| abstract |
Abstract Two-dimensional (2D) molybdenum disulfide ($ MoS_{2} $) nanomaterials have emerged as promising candidates for constructing excellent supercapacitors, but the lack of large-scale, efficient and low-cost methods for preparing $ MoS_{2} $ nanosheets severely hinders its practical application. This study demonstrates an accessible and efficient approach for electrochemical exfoliating bulk $ MoS_{2} $ into high-quality $ MoS_{2} $ nanosheets with size distribution in the range of 1–3 μm and a thickness of several nanometers in an easily available inorganic salt solution. Furthermore, we construct symmetric all-solid-state supercapacitors based on exfoliated $ MoS_{2} $ nanosheets. The 2D structure will provide stable channels to facilitate the intercalation/desorption of ions during charge and discharge, and to a certain extent can prevent deposition and agglomeration. Therefore, compared with the unexfoliated $ MoS_{2} $, as-prepared $ MoS_{2} $ nanosheets show great improvement in supercapacitor performance (the specific capacitance increases from the original 130 F $ g^{−1} $ to 215 F $ g^{−1} $ at 5 A $ g^{−1} $, for instance). In detail, the electrode possesses a specific capacitance of 285 F $ g^{−1} $ at a current density of 2 A $ g^{−1} $ and maintains the great capacitance retention of 83.8% at 8 A $ g^{−1} $. Moreover, the supercapacitor exhibits a high energy density of 136.8 Wh $ kg^{−1} $ at a power density of 2550 Wh $ kg^{−1} $.
