摘要

Hierarchical layered K_0.27MnO₂ microflowers are firstly synthesized via a facile and efficient route based on a topochemical reaction process. As cathode materials for aqueous sodium-ion battery, such microflowers exhibit high reversible capacity, long cyclic life and excellent rate capability. After 100 cycles, a reversible capacity of 68.5mAhg^-1 at a current density of 0.2Ag^-1 is attained in a full cell with K_0.27MnO₂ as cathode and NaTi₂(PO₄)₃as anode. We propose a sodium storage mechanism in K_0.27MnO₂ by analyzing the evolution of structure and interface during charge/discharge process.
