Ionic transport properties of LiCoPO4 cathode material

Abstract: LiCoPO4 has been prepared by the Pechini-type polymerizable precursor method. The formation of the compound is confirmed by XRD analysis. Ion transport mechanism has been analyzed using the AC impedance technique. The conductivity parameters such as ion hopping frequency (ω p) and the charge carrier concentration term (K) have been calculated using Almond and West formalisms. The conductivity relaxation time (τ c) is calculated from the peak frequency of the modulus spectra. [Copyright &y& Elsevier]
