Abstract

The kinetics of the electrochemical insertion of sodium into V6O13 single crystals from an organic solvent based electrolyte have been studied by using the coulometric titration and impedance analysis techniques. The studies have shown that V6O13 is electrochemically active and highly reversible to sodium. A single-phase region was found in the range 0 ≤ x ≤ 0.16 for NaxV6O13 with no distinct discontinuity. The solid-state diffusion kinetics were found to be quite rapid with values for the chemical diffusion coefficient being about 1.1 × 10−8 cm2 s−1 at 25 °C.
