Influence of laser treatment on thermodynamic and kinetic parameters of lithium intercalation process into nanosized SiO2

“…5(a) and (b). The absence of any anomalous behavior in the diffusion coefficient dependence which is calculated from the low frequency range of the Nyquist diagram is just concerned with a nonessential contribution of the Wagner factor into the chemical diffusion coefficient compared to the self-diffusion coefficient change [21].…”

Intercalation current generation in oxygen- and sulfur-doped talc

“…This can be explained by the change in the number of vacancy sites [25], the height of the energy barrier, and the energy of lithium interaction with the matrix. The first two factors determine the changes in the structure of the material and partial amorphization of talc due to the degradation of its crystal structure and the reduc tion of certain elements.…”

“…We can take into account the known [6] equation for the electromotive force of Faraday current generation (2) where is the change in the molar Gibbs energy of the reaction, U(x) is the electromotive force of Li + intercalation, e is the electron charge, is the chemical potential of incorporate lithium in talc, and μ 0 is the chemical potential of lithium in the metallic anode. We can easily see that the form of the discharge curve (except the initial stage of intercalation), which has a considerable contribution from the first and fourth terms of (1), is determined by the concentration dependences of the interaction energy in the intercal ant subsystem and the change in the position of the Fermi level.…”

“…In recent decades, researchers have actively sought for effective cathode materials for electrochemical power sources with lithium anodes [1][2][3][4][5]. These mate rials should satisfy a number of requirements such as the presence of a system of guest sites with the corre sponding energy of incorporation of lithium cations, good diffusion characteristics, and chemical and elec trochemical stability.…”

Fabrication of Electrochemical Sensors Based on Nanostructured Titanium Dioxide Formed through Anodic Oxidation

“…At the same time, titanium oxide film electrodes doped by micro-quantities of metal platinum are known to be efficient catalysts of many electrochemical processes [10,11]. The advantages of such electrode systems include relatively low cost due to low content of the noble metal and high electrocatalytic activity, which in some cases exceeds that of the platinum electrode because of high dispersity of platinum particles in the titanium oxide matrix.…”
