报告摘要:

Due to the exhaust of traditional nonrenewable fossil resources and serious environment pollution, there has been an increasing demand in sustainable and clean energy sources. Research on deformable and wearable electronics has promoted an increasing demand for next-generation power sources with high energy/power density, low cost, light weight, as well as thin and flexible features. One key challenge in flexible electrochemical energy storage devices lies in the development of reliable electrodes with open-framework material, robust structure, and high performance. 3D array electrode design is hot due to its favorable electrolyte affinity and ions/electrons transportation, but there is a disequilibrium where extremely rare reports are available on constructing 3D cathode materials both for application in Li- and Na-ion batteries. Moreover, electrode materials for sodium ion batteries (SIB) is relatively slow-moving compared to those for Li-ion batteries (LIB), because most SIB electrode materials show inferior performance to LIB. Here, we report ingenious approaches for fabrication of 3D array and 2D materials and demonstrate its high-rate capability and long-term rate durability. First principles computational investigation and in situ XRD, Raman observations reveal the working mechanism of the electrode and structure evolution during ions insertion/extraction.
