Delicate synthesis of quasi-inverse opal structural Na3V2(PO4)3/N-C and Na4MnV(PO4)3/N-C as cathode for high-rate sodium-ion batteries
文献摘要：
Poor conductivity and sluggish Na+diffusion kinetic are two major drawbacks for practical application of sodium super-ionic conductor(NASICON)in sodium-ion batteries.In this work,we report a simple approach to syn-thesize quasi-inverse opal structural NASICON/N-doped carbon for the first time by a delicate one-pot solution-freeze drying-calcination process,aiming at fostering the overall electrochemical performance.Especially,the quasi-inverse opal structural Na3V2(PO4)3/N-C(Q-NVP/N-C)displayed continuous pores,which provides interconnected channels for electrolyte permeation and abundant contacting interfaces between electrolyte and materials,resulting in faster kinetics of redox reaction and higher proportion of capacitive behavior.As a cathode material for sodium-ion batteries,the Q-NVP/N-C exhibits high specific capacity of 115 mAh·g-1 at 1C,still 61 mAh.g-1 at ultra-high current density of 100C,and a specific capacity of 89.7 mAh.g-1 after 2000 cycles at 20C.This work displays the general validity of preparation method for not only Q-NVP/N-C,but also Na4MnV(PO4)3,which provides a prospect for delicate synthesis of NASI-CON materials with excellent electrochemical performance.
