Superionics

Abstract

The correlation between the infrared and Raman spectra of lithium borate glasses and their structure has been investigated. The results are consistent with the increasing incorporation of tetrahedrally coordinated boron into the boroxol rings with increasing Li2O content. The spectra reveal the onset of crystallization as the annealing temperature increases. The variation of the ionic conductivity with temperature and composition is shown to be well described by a weak electrolyte theory. The conductivity increases by an order of magnitude when the fractional content of Li2SO4 increases from 0.00 to 0.15. A tight binding method has been used to calculate the energy bands of InSe and the activation energy for motion of Li+ in the Van der Waals gap of InSe. The increase in resistance of a lithium borate glass sample when the Li+ ions are required to flow into the Van der Waals gaps of a contiguous InSe sample has been investigated. Keywords: Solid state battery, Fast ion conductor, Intercalation.
