Electrochemical devices such as fuel cells, electrolyzers, lithium–air batteries, and pseudocapacitors are expected to play a major role in energy conversion/storage the near future. Here, it is demonstrated how desirable bulk metallic glass compositions can be obtained using combinatorial approach shown that these alloys serve platform technology for wide variety of electrochemical applications through several surface modification techniques. As service our authors readers, this journal...
Understanding the interactions between catalyst and electrolyte in Li-O2 systems is crucial to improving capacities, efficiencies, cycle life. In this study, supported noble metal catalysts Pt/C, Pd/C, Au/C were paired with popular solvents dimethoxyethane (DME), tetraglyme (TEGDME), dimethyl sulfoxide (DMSO). The effects of these combinations on stability, kinetics, activity assessed. We show evidence a synergistic effect Pt Pd DMSO-based which enhances kinetics oxygen reduction evolution...
An electrode composed of defective NiO nanostructures supported on carbon nanofibers and immersed in an Li<sup>+</sup>-based aqueous electrolyte is studied using Raman spectroscopy under dynamic polarization conditions to address the charge-storage phenomenon.
Abstract Metal–air batteries, such as Li–air, may be the key for large‐scale energy storage they have highest density among all electrochemical devices. However, these devices suffer from irreversible side reactions leading to battery failure, especially when ambient air is used O 2 source, so a deep understanding over surface chemistry evolution imperative building better Herein, multi‐scale (nano‐micro) FTIR analysis made electrode during cell discharge employing synchrotron infrared...
Engineering education is being called upon to move a student-centered teaching. New challenges demand curriculum that considers set of competencies enable engineers learn autonomously and develop solid technical relevant soft skills. We present top-down methodology for developing competency-based curricula, which was employed conceive new chemical engineering at the University Campinas. Our based on four main steps: i) definition desired profile students with bachelor's degree in Chemical...
This work presents a new methodology to interpret the electrochemical behavior of pseudocapacitors (PCs) which is based on theoretical approach denoted as generic model (GE). Based single premise, GE composed two distinct time constants (τ = RC) used represent narrow-deep (n-d) and large-shallow (l-s) heterogeneous surface structures incorporating different defects (e.g., cracks, fissures, pores, etc.), incurs in so-called distributed capacitance resistance phenomena. Five transition metal...
Here we report the influence of anion shape over solvation structure and transport properties commonly employed Li–O<sub>2</sub>electrolytes discuss their implications for device.
Lithium–metal batteries, such as Li–O 2 , are some of the most promising candidates for high-performance energy storage applications, however, their performance is still limited by electrolyte instability.
