研究目的
To study the degradation of Na2Ti3O7-based electrodes during cycling and to understand the underlying mechanisms.
研究成果
The degradation of Na2Ti3O7-based electrodes during cycling is attributed to the splitting of sodium titanate intergrown plates and the constant growth of solid electrolyte interface on the surface of Na2Ti3O7 particles. The rate of degradation decreases with increasing cycling current.
研究不足
The study focuses on the degradation mechanisms of Na2Ti3O7-based electrodes but does not explore the optimization of electrode materials or cycling conditions to mitigate degradation.
1：Experimental Design and Method Selection:
The study employed galvanostatic cycling, cyclic voltammetry, Raman spectroscopy, and electrochemical impedance spectroscopy to investigate the degradation of Na2Ti3O7-based electrodes.
2：Sample Selection and Data Sources:
Sodium titanate was prepared by a citric method and characterized using XRD, SEM, BET-specific surface area, and Raman spectroscopy.
3：List of Experimental Equipment and Materials:
Equipment included a Rigaku D/MAX 2200 diffractometer, Carl Zeiss NVision 40 station, Sorbtometer-M analyzer, DXRxi Raman Imaging Microscope, AZRVRIK 50 mA–10 V battery test system, and Solartron 1255 frequency analyzer. Materials included tetrabutyl titanate, anhydrous sodium carbonate, and carbon black.
4：Experimental Procedures and Operational Workflow:
Electrodes were prepared using a standard paste method, and electrochemical measurements were conducted in three-electrode sealed cells with sodium auxiliary and reference electrodes.
5：Data Analysis Methods:
XRD patterns were processed with Rigaku Application Data Processing software, and impedance spectra were analyzed using Zplot? software.
