Journal ArticleDOI
Vapor-Phase Polymerization of 3,4-Ethylenedioxythiophene: A Route to Highly Conducting Polymer Surface Layers
Bjorn Winther-Jensen,Keld West +1 more
TL;DR: In this article, a base-inhibited vapor-phase polymerization was proposed for poly-3,4-ethylenedioxythiophene (PEDT) with a conductivity exceeding 1000 S/cm.
Journal ArticleDOI
Diffusion impedance in planar, cylindrical and spherical symmetry
Torben Jacobsen,Keld West +1 more
TL;DR: In this article, the Laplace transformed diffusion equation is solved for finite diffusion in planar, cylindrical and spherical geometry with a Nernstian or an impermeable diffusion layer boundary condition.
Journal ArticleDOI
Mechanism of Actuation in Conducting Polymers: Osmotic Expansion
TL;DR: In this article, a thermodynamic description of the osmotic expansion is worked out, and the model is compared with measurements on PPy(DBS) films, showing that the expansion decreases as the electrolyte concentration is increased.
Journal ArticleDOI
Lithium insertion in different TiO2 modifications
TL;DR: In this paper, the insertion of Li into the three titanium dioxide modifications, anatase, rutile, and TiO2(B), was studied primarily by electrochemical techniques.
Journal ArticleDOI
Dynamic Aspects of Solid Solution Cathodes for Electrochemical Power Sources
TL;DR: In this article, the authors discuss the interaction between battery requirements, in particular for vehicle propulsion, and electrochemical and constructional factors, and show that the energy obtainable at a given load is limited by saturation of the surface layers of cathode particles with cations, and that the time before saturation is determined by diffusion of cations and electrons into the host lattice.
