Interference blockage of electron tunneling and pseudo-Faraday hypercapacity for C-SiO2 nanocomposites

The thermodynamic and kinetic regularities of the intercalation of lithium into C-SiO 2 nanocomposites are studied. The dependence of the differential capacity and kinetic intercalation parameters on the size of nanocomposite particles is established. According to theoretical analysis, the obtained...

Description
Summary:The thermodynamic and kinetic regularities of the intercalation of lithium into C-SiO 2 nanocomposites are studied. The dependence of the differential capacity and kinetic intercalation parameters on the size of nanocomposite particles is established. According to theoretical analysis, the obtained results are explained as resulting from the quantum-mechanical effect of the interference blockage of the tunneling of an electron into a nonmetallic nanoparticle. An impedance model of processes and its parametric identification are given. A new class of electrochemical energy generators is proposed.
