| 英文摘要 | Delivery of high-energy density with long cycle life is facing a severe challenge in developing cathode materials for rechargeable sodium-ion batteries (SIBs). Here a composite Na0.6MnO2 with layered-tunnel structure combining intergrowth morphology of nanoplates and nanorods for SIBs, which is clearly confirmed by micro scanning electron microscopy, high-resolution transmission electron microscopy as well as scanning transmission electron microscopy with atomic resolution is presented. Owing to the integrated advantages of P2 layered structure with high capacity and that of the tunnel structure with excellent cycling stability and superior rate performance, the composite electrode delivers a reversible discharge capacity of 198.2 mAh g(-1) at 0.2C rate, leading to a high-energy density of 520.4 Wh kg(-1). This intergrowth integration engineering strategy may modulate the physical and chemical properties in oxide cathodes and provide new perspectives on the optimal design of high-energy density and high-stable materials for SIBs. |
