Furthermore, the imaginary electric modulus, as studied by the Kohlrausch-Williams-Watts function, showed non-Debye relaxation behavior, with compositional effects becoming more significant at higher frequencies.Temperature-dependent impedance investigation and modeling with an analogous circuit indicated that ionic and polaronic conduction, as well as Li<sup>+</sup> ion diffusion, occurs simultaneously in LVB4, LVB5, and LVB6 glasses. The activation energy estimated from conductivity, electric modulus, and impedance analyses revealed a significant connection, confirming the consistency of the results.
