Quantum mechanic tunelling and effciency of Faradey current-generatig process in porous nanostructures

Abstract

Thermodynamics and kinetics of lithium intercalation into C-SiO 2 nanocomposites are investigated. Dependencies of both differential capacity and intercalation kinetics on the nanocomposite size are established. The processes are analyzed in terms of the impedance model. The obtained results are explained based on the quantum effect of interference blockade of electron tunneling into a nonmetallic nanoparticle. Propositions for the new electrochemical energy storage technology are presented.

Lithium–Iron Fluoride Battery with In Situ Surface Protection

“…The majority of pores within AC are distributed within 1–4 nm. As a result, less than 2 nm separation distances exist between the center of FeF 2 and conductive pore walls, which permits quantum mechanical tunneling of electrons to/from electrochemical reaction sites . The smooth surface of the FeF 2 infiltrated AC particles indicated a good efficiency of our synthesis procedure, where no nanoparticles present outside the carbon pores.…”

INCREASE OF EFFICIENCY OF Li+-INTERCALATED CURRENT GENERATION IN SUPRAMOLECULAR ENSEMBLES WITH HIERARCHICAL ARCHITECTURE MCM-41〈HYDROQUINONE〉

“…The main conclusion of the above mentioned analysis, (see also 27 ), is the nonmonotonic change of electron tunneling into the host. Since the tunneling determines the current generation phenomenon in the doublet-matrix structure, the result can be regarded as an explanation for the experimentally observed behavior of the current generation characteristics.…”
