Triethylammonium-propanesulfonic acid tetrafluoroborate (TEA-PS center dot BF4) is used as an electrolyte in the water electrolysis. The electrolysis of water with this ionic conductor produces high current densities with high efficiencies, even at room temperatures. A system using TEA-PS center dot BF4 in an electrochemical cell with platinum electrodes has current densities (i) up to 1.77 A cm(-2) and efficiencies between 93 and 99% in temperatures ranging from 25 degrees C to 80 degrees C. The activation energy observed with TEA-PS center dot BF4 is ca. 9.3 kJ mol(-1), a low value that can be explained by the facilitation of proton transport in the organised aqueous ionic liquid media. The unexpectedly high efficiency of this system is discussed by taking into account the high conductivities associated with the Bronsted and Lewis acidity characteristics associated with these ionic conductive materials.

Synthesis and Adsorbent Properties of Silica-Titanate Nanoarchitectures Produced by Unrolling Titanate Tubular Sheets

Anderson J. Schwanke, Wesley Monteiro, Leticia G. da Trindade, Elson Longo, Katia Bernardo-Gusmao, Michele O. de Souza

Summary: Microporous and mesoporous nanocomposites based on silica and titanate were synthesized by unrolling sodic titanate nanotubes and introducing surfactant species and silica species between the unrolled titanate nanotubes. The resulting nanoarchitectures exhibit higher specific surface areas and improved adsorption capacities compared to the pristine titanate nanotubes. Kinetic and isotherm analyses indicate that the adsorption process follows pseudo-second-order kinetics and occurs through multilayer adsorption onto the nanocomposites, rather than onto uniform sites.

Examining the effects of silicon based additives on the long-term cycling capabilities of cylindrical cells

Anmol Jnawali, Matt D. R. Kok, Francesco Iacoviello, Daniel J. L. Brett, Paul R. Shearing

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: An efficient phase inversion-impregnation approach is developed to fabricate BaO-decorated Ni8 mol% YSZ anode-supported tubular solid oxide fuel cells (SOFCs) with anti-coking properties. BaO nanoislands are successfully introduced inside the Ni-YSZ anode, leading to higher peak power densities and improved stability in methane fuel. Density functional theory calculations suggest that the loading of BaO nanoislands facilitates carbon elimination by capturing and dissociating H2O molecules to generate OH.

Summary: Li-CO2 batteries, which utilize CO2 and have a high energy density, are hindered in practical applications due to slow kinetics and safety hazards. This study introduces a stable and highly conductive ceramic-based solid electrolyte and a metal-organic framework catalyst to improve the safety and performance of Li-CO2 batteries. The optimized Li-CO2 cell shows outstanding specific capacity and cycle life, and the post-cycling analysis reveals the degradation mechanism of the electrodes. First-principles calculations based on density functional theory are also performed to understand the interactions between the catalyst and the host electrode. This research demonstrates the potential of MOF cathode catalyst for stable operation in Li-CO2 batteries.

Towards understanding the functional mechanism and synergistic effects of LiMn2O4-LiNi0.5Mn0.3Co0.2O2 blended positive electrodes for Lithium-ion batteries

Dimitrios Chatzogiannakis, Marcus Fehse, Maria Angeles Cabanero, Natalia Romano, Ashley Black, Damien Saurel, M. Rosa Palacin, Montse Casas-Cabanas

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
