35. In-Situ Localized pH, pNa and Dissolved O2 Measurements During Charge-Discharge of Mixed Ni-Co Hydroxide Electrodes.

Author

Abstract

This work reports, for the first time, the use of ion-selective localized electrochemical techniques to elucidate the charge-discharge mechanism of nickel-cobalt hydroxide electrodes for electrochemical energy storage. The charge-discharge mechanism of electrodeposited nickel-cobalt hydroxide electrodes was studied in Na2SO4 0.05 M by localized in situ measurements of pH, pNa and dissolved O2 during cyclic voltammetry. Local pH and pNa distributions were recorded using micro-potentiometric sensors with liquid membrane, while dissolved O2 was monitored using a fiber-optic microsensor. These original results highlight how localized potentiometry can provide new insights to better understand the charge mechanism of metal (hydr)oxide electrodes by directly measuring the concentrations/activities of relevant species at the electrode-electrolyte interface during charge-discharge.

Abstract

Corrosion of AlZnMg coated steel in chloride media is a complicated process, which progress is determined not only by the electrode reactions but also by the local pH and formation of soluble and insoluble corrosion products. In order to adequately describe and predict the corrosion behavior of steel/AlZnMg cut‐edge, a multi‐ion transport, and reaction model (MITReM) is built. Such model takes into account the transport of species in the solution together with their production/consumption in electrochemical and chemical reactions. The main aim of this work is the validation of a numerical model for describing and predicting corrosion of steel/AlZnMg cut‐edge in immersed conditions. This first part describes the experimental work done to obtain model input parameters and validation measurements. The metallic coatings are characterized experimentally with respect to their composition and microstructure, global and local electrochemical behavior (polarization curves, AESEC, and SVET). Local distribution of corrosion products and local pH are also characterized. No blocking effect of the precipitated corrosion products has been observed and dedicated measurements are performed to validate this observation. Based on the experimental input from this part, numerical models of cut‐edge corrosion with different levels of details are developed in Part II. [ABSTRACT FROM AUTHOR]

41. Quasi-simultaneous Mapping of Local Current Density, pH and Dissolved O2.

Author

Taryba, Maryna G., Montemor, M. F., and Lamaka, S. V.

Subjects
*CURRENT density (Electromagnetism), *OXYGEN, *PHOSPHORS, *POTENTIOMETRY, *MICROELECTRODES, *CORROSION & anti-corrosives
Abstract

For the first time we report on quasi-simultaneous mapping of local current density, pH and concentration of dissolved O2. The three micro-probes were positioned 50 micron apart from each other and 50 to 100 µm above the cut-edge metal coated steel sample. The vibrating probe recorded the local current density and glass-capillary micro-electrode measured local pH. Additionally, two different micro-probes were used for DO measurements: either an amperometric micro-probe or micro- optode was coupled with the other two sensors using the triple head stage. The data on local distributions were acquired quasi-simultaneously (within ≤ 2.8 s) and, hence, are correlated in space and time. [ABSTRACT FROM AUTHOR]
