摘要：
The sodium super ionic conductor (NASICON) structured Na3MnTi(PO4)(3) is attractive due to the eco-friendly and low-cost Na-Mn-Ti-P-O system. However, Na3MnTi(PO4)(3) suffers from low Coulombic efficiency, inferior electronic conductivity and limited specific capacity basing on two-sodium-exchange. To address these multifaceted issues, herein, an interpenetrating graphene encapsulated Na3MnTi(PO4)(3) particles with carbon-shell covering material (rGO@NMTP-C) was synthesized. By regulating cut-off voltages, a three-electron reaction was realized and Coulombic efficiency of the rGO@NMTP-C was found to increase from <96% to 100% due to the fast kinetics that enhanced by Ti3+/Ti4+ redox, which was verified by EIS and GITT. Sodium storage mechanism of the multielectron reaction was deeply studied by ex-situ XRD and DFT calculations. It shows that the enhanced reversibility synergizing with multifunctional 3D conductive network and the contribution of pseudocapacitance, makes rGO@NMTP-C a promising cathode candidate, which can exhibit a remarkable discharge capacity of 173 mA h g(-1). Additionally, for the first time, the rGO@NMTP-C achieves outstanding high rate capability of 92.4 mA h g(-1) at 50C, and cycling stability of 74.5% of capacity retention after 3500 cycles at 20C. High performance full cells were also realized for practical utilization of SIBs.
