Nonlinear impedance spectroscopy of composite materials based on potassium~polytitanate

Experimental studies of the electrochemical and electrophysical properties of protonated potassium polytitanate and sodium-modified pryderite were carried out using the method of nonlinear impedance spectroscopy. The frequency dependencies of the resistance of the volume of grains and grain boundaries were determined depending on the magnitude of the polarization voltage (DC) and on the value of the perturbation signal (AC).

Nonlinear effects in a cell with a solid electrolyte based on protonated potassium polytitanate

In this paper, the electrochemical and electrophysical properties of protonated potassium polytitanate synthesized at pH values varying from 3.11 to 8.88 depending on the magnitude of the polarization voltage and the magnitude of the measured signal were studied by the method of impedance spectroscopy. The values of effective conductivity, relaxation times, frequency dependences of the loss tangent, and dielectric permittivity are determined.
