| مستخلص: |
For the first time, environmentally friendly sulfur‐rich pyramidal MnS2 synthesized via a single‐step hydrothermal process is used as a high‐performance anode material in Li‐ion and Na‐ion batteries. The superior electrochemical performance of the MnS2 electrode along with its high compatibility with ether‐based electrolytes are analyzed in both half‐ and full‐cell configurations. The reversible capacities of ≈84 mAh g−1 and ≈74 mAh g−1 at a current density of 50 mA g−1 are retained in the Li‐ion and Na‐ion full‐cells, respectively, over 200 cycles with excellent capacity retentions. Moreover, important findings regarding activation processes in the presence of a new phase transition and protective electrolyte interphase layer are revealed using ab initio density function theory calculation and in situ potentio‐electrochemical impedance spectroscopy. The detailed complex redox mechanism of MnS2 in Li/Na half‐cells is also elucidated by ex situ X‐ray photoelectron spectroscopy. [ABSTRACT FROM AUTHOR] |
