Structural and conductivity studies of LiNi0.5Mn0.5O2 cathode materials for lithium-ion batteries

, AC conductivity exhibits dispersion and increases with an increase in frequency and temperature [43] . The maximum AC conductivity of the synthesized sample is 1.03 × 10 −6 S/cm at 60 °C. Fig. 6 Variation of AC conductivity of LiNi 0.5 Mn 0.5 O 2 material as a function of frequency at different temperatures. The activation energies for AC conductivity at different temperature regions were obtained by measuring the slope of the curves and using the Arrhenius relationship: σ ac = σ 0 exp ( − E a k B T ) $${\sigma _{{\text{ac}}}} = {\sigma _0}\exp
