Abstract

Optical characterization from 300-1600 nm shows that lithium intercalated V₂0₅ exhibits cathodic coloration in the near-infrared and anodic coloration on the blue and near-UV (<450 nm). The anodic coloration is associated with a shift in the optical gap to shorter wavelengths. The spectral coloration efficiency in the near-IR (600-1600 nm) is quite low, typically less than 15 cm²/C. Absorption coefficients and solar transmittance of Li_xV₂O₅ are reported as a function of Li concentration (x).
