Electrochemical cells were prepared by depositing a fast ion conducting Li2O-P2O5-Nb2O5 glass layer, and a metallic Li layer, onto a cathode which was in the form of thin layers or bulk samples of V2O5-40TeO2. Alternating-current impedance measurements were used to determine the Li diffusivity (table 142).
