Abstract
Solvent effects on the intercalation of lithium ions in niobium triselenide electrodes have been investigated by cathodic polarization measurements in propylene carbonate (PC), acetonitrile (AN), 1,2-dimethoxyethane (DME), tetrahydrofuran (THF) and their 50% vol./vol. mixtures with PC, using 1 M LiClO4 as the supporting electrolyte. The polarization follows the general order PC≈PC/AN≈PC/THF>THF>PC/DME>DME>AN which reflects the probable size of the solvated lithium ion. This suggests that intercalation of Li+ into the host lattice occurs without desolvation. Lattice diffusion coefficients of Li+ in NbSe3 in the various solvents have been determined by an intermittent galvanostatic technique and found to be in the order AN>DME≈PC/DME>PC/AN>PC. This has also been explained in terms of solvation effects and the composition of the resultant Li+ solvation shell.
