【 摘 要 】

Influence of the ultrasound on talc (Mg3Si4O10(OH)2) cathode material was experimentally investigated. The Gibbs׳ energy change of the Li+-intercalation process, the diffusion coefficient in LixMg3Si4O10(OH)2, the charge transfer resistance and the capacitance of the electric double layer were studied in electrochemical cells, based on initial and ultrasonic treated talc. The obtained results were interpreted within the nonlinear diffusion-deformation model, which involved formation of vacancy nanoclusters under ultrasonic influence at temperatures lower than a critical value.
