WebAug 11, 2024 · Using three Debye relaxations, the static permittivity value, or dielectric constant, is extrapolated to 18.5, which is compared to 18.7 for the neat solvent mixture. The EC solvent is found to strongly coordinate with the Li + cations of the salt, which results in a loss of dielectric contribution to the electrolyte. WebThe Clausius–Mossotti relation expresses the dielectric constant (relative permittivity, εr) of a material in terms of the atomic polarizability, α, of the material's constituent atoms and/or molecules, or a homogeneous mixture thereof. It is named after Ottaviano-Fabrizio Mossotti and Rudolf Clausius. WebA refined use of the same model yields a apparently more general equation for the dielectric constant of a mixture, namely (e 1 3 − e1 1 3 )/ (e2 1 3 −e1 1 3 ) = v2 , where v2 = the volume fraction of the dispersed component, e2 = the dielectric constant of this component and e1 = the dielectric constant of the other component. ヴァイオレットエヴァーガーデン 上巻
