| 英文摘要 | MnO_2 has attracted great interest in working as the cathode of zinc ion batteries. However, the development of high-capacity, high-energy-density, and durable manganese-based cathodes with an easy synthesis strategy and proper energy storage mechanism remains an ongoing challenge. Herein, a facile plasmainduced strategy was demonstrated to introduce oxygen vacancies into the ε-MnO_2 , and the obtained oxygen vacancies-rich ε-MnO_2 nanosheets(ε-MnO_(2-x)) show satisfactory electrochemical performances.Furthermore, an appropriate energy storage mechanism for dissolution/deposition was proposed. Thanks to a synergistic effect of the oxygen vacancies in ε-MnO_2 nanosheets and the exposed free-standing collector for Mn~(2+) dissolution/deposition, the ε-MnO_(2-x)nanosheets electrode delivers a remarkable capacity(337 mAh g~(-1) at 0.1 A g~(-1)) and exhibits an ultrahigh energy density of 462 Wh kg~(-1)(based on the weights of the cathode active material). Furthermore, impressive durability with 85.9% capacity retention after 1000 cycles was obtained. The superior electrochemical performance makes the plasma-induced strategy promising for designing advanced metal oxide electrode materials for high-performance aqueous zinc ion batteries. |
