is designed and synthesized by a simple solid-state method and investigated as a positive electrode material for sodium-ion batteries. The attractive long cycling stability is demonstrated by the capacity retention of 85% after 150 cycles at 1 C rate without phase transformation. The reversible Cu/Cu redox couple in P2 phase oxides is proved for the first time.
通过简单的固态方法设计并合成，并作为钠离子电池的正极材料进行研究。在1 C倍率下循环150次后容量保持率为85%，且无相转变，证明了其具有吸引人的长循环稳定性。首次证明了P2相氧化物中可逆的Cu/Cu氧化还原对。
