Lithium conducting glasses; electrical conductivity; nucleation and crystallization; glass transition temperature.

The study of electrical conductivity of 30Li₂O : (70 – 𝑥) B₂O₃ : 𝑥V₂O₅ glass samples has been carried out. The results have been explained by dividing the temperature range into two regions. In region I, conductivity shows Arrhenius behaviour for all the samples. The conductivity increases with addition of V₂O₅. The results have been explained in the light of Anderson and Stuart Model. In region II, an anomalous enhancement in the conductivity is observed for all the samples up to certain temperature beyond which the conductivity decreases. The enhancement in the conductivity in the annealed glass sample has been attributed to nanocrystallization.
