The study investigates the Na-ion storage performance of TiO2 nanosheets in a diglyme-based electrolyte, focusing on capacity and cycling stability.
Anodes were constructed using TiO2 nanosheets and tested in diglyme/NaPF6 electrolyte.
Interfacial properties were analyzed using ATR-FTIR and XPS techniques.
Cycling performance was compared with conventional carbonate-based electrolytes.
Achieved a specific capacity of 214 mAh g-1 at 25 mA g-1 and retained 67% capacity after 6000 cycles.
Demonstrated 135 mAh g-1 rate capability at 1 A g-1 and nearly 100% Coulombic efficiency.
Pseudocapacitive contribution from TiO2 was significantly higher (∼59%) than conventional systems (18%).
