Historical development of theories of the electrochemical double layer

Measurements of the double layer capacitance for electrodes in supercritical CO2/acetonitrile electrolytes

“…In earlier studies [20] we investigated the phase behaviour and conductivity for CO 2 In the experiments presented below the conditions were selected so that the system was always in the single phase region. The mole fractions (x 1 = CO 2 , x 2 = CH 3 CN, x 3 = electrolyte) were dependant on the concentration of electrolyte added and all fell in the range: For the CO 2 /CH 3 CN system our earlier work showed that solutions of reasonably high conductivity (22- For each solution electrochemical impedance measurements were made for a range of potentials where there was little or no background Faradaic electrochemistry.…”

“…Models are well developed for conventional metal/electrolyte solution interfaces with descriptions in terms of the classical Helmholtz, Gouy-Chapman, and Stern Triple layer models [2] based originally in classical experimental studies of the mercury/sodium fluoride system. These models are supported by extensive experimental studies and modelling for aqueous solutions and for high dielectric organic solvents such as acetonitrile.…”

Basic interfacial thermodynamics and related mathematical background

“…Interfacial thermodynamics is the study of the application of thermodynamics to interfacial phenomena, addressing topics, including adsorption, interfacial energies, interfacial tension, and superficial charge, and about relations among them [see e.g., [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Adsorption of one or more of the components, at one or more of the phase boundaries of a multicomponent, multiphase system, is said to occur if the concentrations in the interfacial layers are different from those in the adjoining bulk phases.…”

“…First, to introduce the reader to the topic, a reasonably simple thermodynamic treatment of interfaces, together with a brief description of the models widely used in the literature, is presented (more detailed discussions can be found in several reviews and research papers [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]). …”

Twenty years of the Journal of Solid State Electrochemistry

“…Progress in electroanalysis and electrochemical sensors is currently certainly slower than progress in power sources and storage devices, but some spectacular developments are occurring: the development of dating procedures for metals (see the [34], voltammetry at three-phase junction [35], DOCC site concept [36], voltammetry at three-phase junction [5], corrosion current densities [37], non-Marcus model for electrostatic fluctuations in long-range electron transfer [38], electron transfer [39,40], Tafel slopes [41], convolution [42], IL double layer [43], equivalent circuit for C-based supercapacitors [44], single molecule transistor [45], steady-state voltammetry [46], capillarity and electrocapillarity of solid interfaces [47], normally rather rare in all journals, is another topic which will continue to be cultivated in our journal. We will also continue to draw the attention of our readers to the history of electrochemistry, e.g., history of platinum single crystal electrochemistry [48], double layer effects in electrode kinetics [49], electrochemical phase formation [50], nonaqueous media in electrochemistry [51,52], lithium batteries [53], free energy relationships [54], solid electrolyte fuel cells [55], glass electrode [56], electrochemical stripping techniques [57], electrode kinetics [58], osmotic theory [59], and theories of electrochemical double layer [60], ionic strength and electrode kinetics [61], Nernst equation [62], as we believe that this is a prerequisite for knowing where we have come from and where we have to go. The future of the journal will depend on new and younger editors, who will certainly bring in fresh ideas and enthusiasm.…”
