Study of degradation of Na2Тi3O7-based electrode during cycling

The degradation of electrodes based on sodium titanate (Na 2 Ti 3 O 7 ) was studied using the methods of galvanostatic cycling, cyclic voltammetry, Raman spectroscopy, and electrochemical impedance spectroscopy. It is established that during the cycling, there is splitting of sodium titanate intergr...

Beschreibung
Zusammenfassung:The degradation of electrodes based on sodium titanate (Na 2 Ti 3 O 7 ) was studied using the methods of galvanostatic cycling, cyclic voltammetry, Raman spectroscopy, and electrochemical impedance spectroscopy. It is established that during the cycling, there is splitting of sodium titanate intergrown plates and constant growth of solid electrolyte interface on the surface of Na 2 Ti 3 O 7 particles. These factors account for the degradation of Na 2 Ti 3 O 7 at cycling.
