Mitigating concentration polarization for highly reversible plating/stripping electrochemistry: Li versus Na

Journal of Materials Chemistry A, 2019
Li and Na metal anodes have quite different plating/stripping reversibilities in literature; here we find that weaker concentration polarization is responsible for the better reversibility of Na metal anodes than that of Li metal anodes.

ELECTROCHEMISTRY OF THE NICKEL OXIDE ELECTRODE: PART III. ANODIC POLARIZATION AND SELF-DISCHARGE BEHAVIOR [PDF]

Canadian Journal of Chemistry, 1962
Further evidence that the rate-controlling process in self-discharge of the nickel oxide electrode is the anodic partial reaction of oxygen evolution is reported and is based on: (a) comparison of the heats of activation for open-circuit oxygen evolution and for d-c.

Correlation of surface concentration polarization with the surface electrochemistry of a permselective Membrane: An ex situ electrical impedance spectroscopy study

Journal of the Taiwan Institute of Chemical Engineers, 2017
Abstract Surface concentration polarization induces fouling processes accompanied by changes in the resistance of a semipermeable membrane, but the connection between these two phenomena has not yet been evaluated. Here, we propose to connect them by introducing the concept of pH equivalent (pHeq), which is used to describe the electrical properties ...

Induced polarization and surface electrochemistry

GEOPHYSICS, 2007
Induced-polarization (IP) responses arising from activation overvoltage are investigated, with the goal of relating established electrochemical properties and processes to IP time constants. In activation overvoltage, an electrical double layer with a well-defined areal capacitance forms at the mineral-electrolyte interface.

Electrochemistry of indium. Part II. Electrolytic polarization at n-type indium oxide electrode

Journal of the Chemical Society A: Inorganic, Physical, Theoretical, 1970
Anodic polarization of n-type indium oxide has been studied both in the presence and absence of redox systems. Comparison of potential/current curves for the systems showed that the current multiplication factor, α, was in the range 1·88–2·73. These results taken together with the other electrochemical properties of the oxide are consistent with it ...

Crystal Structure, Spin Polarization, Solid-State Electrochemistry, and High n-Type Carrier Mobility of a Paramagnetic Semiconductor: Vanadyl Tetrakis(thiadiazole)porphyrazine

Inorganic Chemistry, 2011
We report the synthesis, crystal structure, and magnetic, electrochemical, and carrier-transport properties of vanadyl tetrakis(thiadiazole)porphyrazine (abbreviated as VOTTDPz) with S = ½. X-ray crystal analysis reveals two polymorphs, the α and β forms; the former consists of a 1D regular π stacking, while the latter forms a 2D π network.

Dynamic polarization of lipid bilayers as a special case in the electrochemistry of liquid/liquid interfaces

Analytica Chimica Acta, 1987
Abstract Dynamically obtained current/voltage curves of bilayer lipid membranes partitioning a solution of lipophilic ions are compared with the results of the type expected in a voltammetry experiment involving ionic transport across a liquid/liquid interface.

The Electrochemistry of Nickel

Journal of The Electrochemical Society, 1963
Abstract : The anodic dissolution of Ni was studied in acidified chloride, sulfate, and perchlorate solutions under a variety of non-passivating conditions. The Tafel slopes at 45 deg C are approximately 0.085, 0.115, 0.12, respectively. The lower value of the Tafel slope in chloride solutions is attributed to specific adsorption.
