Abstract

The compositional variation of the kinetic and thermodynamic processes of sodium insertion into V6O13 single crystal electrodes have been examined using cells of the type Na| (PEO)8·NaCF3SO3|V6SO13 over a range of temperature and stoichiometry. Coulometric titration and ac impedance data have shown sodium to be highly stable and reversible to V6O13. The chemical diffusion coefficient was found to be fairly constant over a wide stoichiometry range with a mean value of about 2.9 ×10-8cm2s-1.
