Investigating Pitting Behavior of Stainless-Steel for Canister in Vertical Position Using Electrochemical Acceleration Test J. Electrochem. Soc. (IF 3.9) Pub Date : 2024-04-16 Thuy Chung Nguyen, Jin-Seok Yoo, Jung-Gu Kim
Stainless steel is renowned for its corrosion resistance and is widely used in constructing canisters for nuclear waste containment. These canisters are designed to endure burial in soil for over a century, making it crucial to study the long-term corrosion behavior of SS in this specific context. However, analysis of the corrosion behavior of SS is challenging due to its slow corrosion rate. Therefore

Effects of Pt Loading onto SnO2 Ordered Porous Thin Films on Potentiometric Hydrogen Sensing Properties J. Electrochem. Soc. (IF 3.9) Pub Date : 2024-04-15 Hong Zhang, Zhou Li, Haowei Zhu, Jianxin Yi
Ordered Pt/SnO2 composite porous thin films were prepared for fabrication of planar mixed-potential hydrogen sensors. Characterization of the Pt/SnO2 films revealed that Pt elements were primarily loaded in Pt° form on the SnO2 film surface and did not significantly change the morphology of the film electrodes. The potentiometric response of Pt/SnO2 thin films to hydrogen varied with the Pt loading

Lignin is the second most common biopolymer after cellulose and the most-available renewable source of aromatic groups in nature. The alkaline method was used to extract lignin from Phoenix dactylifera seeds powder. The current research aims to use extracted lignin as a reducing and stabilizing agent for ecofriendly manufacturing of silver nanoparticles (Lig-AgNPs). The prepared Lig-AgNPs were characterized

ATR-SEIRAS Method to Measure Interfacial pH during Electrocatalytic Nitrate Reduction on Cu J. Electrochem. Soc. (IF 3.9) Pub Date : 2024-04-15 Elizabeth R. Corson, Jinyu Guo, William A. Tarpeh
This study reports the accuracy and applications of an attenuated total reflectance–surface-enhanced infrared absorption spectroscopy (ATR–SEIRAS) technique to indirectly measure the interfacial pH of the electrolyte within 10 nm of the electrocatalyst surface. This technique can be used in situ to study aqueous electrochemical reactions with a calibration range from pH 1–13, time resolution down to

Elucidation of Mass Transport Phenomena in Highly Concentrated Electrolytes during Current Cycling Using In-Situ Interferometry and Finite Difference Method J. Electrochem. Soc. (IF 3.9) Pub Date : 2024-04-15 Go Kamesui, Kei Nishikawa, Mikito Ueda, Hisayoshi Matsushima
Understanding electrolyte mass transfer during charge–discharge reactions is essential for developing next-generation storage batteries with high energy densities. In this study, we investigated Li+ transport in a highly concentrated electrolyte (HCE) consisting of an equimolar mixture of lithium bis(fluorosulfonyl)amide (LiFSA) and tetraglyme (G4) under current reversal and re-reversal. Concentration

Degradation of Styrene-Poly(ethylene oxide)-Based Block Copolymer Electrolytes at the Na and K Negative Electrode Studied by Microcalorimetry and Impedance Spectroscopy J. Electrochem. Soc. (IF 3.9) Pub Date : 2024-04-15 Silin Xing, Anna Khudyshkina, Ulf-Christian Rauska, Andreas J. Butzelaar, Dominik Voll, Patrick Theato, Jens Tübke, Fabian Jeschull
The electrode-electrolyte interface of alkali metal electrodes and solid polymer electrolytes (SPE) is challenging to access because solid electrolytes are difficult to remove without damaging the interphase region. Herein, the two non-invasive techniques isothermal microcalorimetry (IMC) and electrochemical impedance spectroscopy (EIS) are combined to explored degradation processes of reactive sodium

Influence of the Complex Interface between Transport and Catalyst Layer on Water Electrolysis Performance J. Electrochem. Soc. (IF 3.9) Pub Date : 2024-04-15 Tien-Ching Ma, Andreas Hutzler, Boris Bensmann, Richard Hanke-Rauschenbach, Simon Thiele
The interface design between anode catalyst layer (ACL) and porous transport layer (PTL) significantly influences the performance of proton exchange membrane water electrolyzers. Lately, the influence of the ACL/PTL interface on performance is more intensively investigated, including modeling approaches. Contrary to other models that apply through-plane resolved modeling, in-plane models better characterize

Examining Performance Loss Mechanisms in Lithium-Ion Batteries with the High-Voltage Mn-Rich Spinel Positive Electrodes J. Electrochem. Soc. (IF 3.9) Pub Date : 2024-04-15 Pavan P. Badami, Stephen E. Trask, Seoung-Bum Son, Marco-Tulio F. Rodrigues, Daniel P. Abraham
The high-voltage spinel, with the nominal composition of LiNi0.5-xMn1.5+xO4 (LNMO), could be a sustainable alternative to the layered-oxide positive electrodes used in lithium-ion batteries. However, commercial acceptance has been limited as LNMO cells display rapid performance loss during cycling. To examine reasons for this loss we prepared cells with LNMO-based positive and either graphite or lithium
