摘要：
We study the influence of the ultrasonic treatment of pyrophyllite in different media on its structure and charge transfer and analyze the dependences of changes in the Gibbs free energy, resistance to charge transfer, and capacitance of the Helmholtz layer caused by the acoustic action on the amount of “guest” lithium x. It is shown that abnormally high diffusion coefficients of lithium cations for all investigated values of x represent a specific feature of the kinetics of intercalation in LixAL2(OH)2[Si2O5]2.
