Plasma-induced ε-MnO2 based aqueous zinc-ion batteries and their dissolution-deposition mechanism
文献摘要：
MnO2 has attracted great interest in working as the cathode of zinc ion batteries.However,the develop-ment of high-capacity,high-energy-density,and durable manganese-based cathodes with an easy synthe-sis strategy and proper energy storage mechanism remains an ongoing challenge.Herein,a facile plasma-induced strategy was demonstrated to introduce oxygen vacancies into the ε-MnO2,and the obtained oxygen vacancies-rich ε-MnO2 nanosheets(ε-MnO2-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-Mn02 nanosheets and the exposed free-standing col-lector for Mn2+dissolution/deposition,the ε-MnO2-x nanosheets electrode delivers a remarkable capac-ity(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.
