Summary: The research addresses the insufficient stability of the electrolyte towards oxidation in high-voltage lithium-ion cathode materials, and introduces a new combination of electrolyte additives to improve battery performance. The synergistic effect of TTSPi and TFEC additives significantly enhances cycling stability, capacity, and coulombic efficiency in lithium-ion cells with a voltage higher than 4.5 V, which can be further improved with the addition of lithium bis(oxalato)borate.

Summary: In this study, the failure mechanism of stored NCM811 cathode material was investigated from the perspective of electrolyte/electrode interfaces. The impurities generated on the NCM811 surface during storage were found to catalyze the oxidative decomposition of electrolytes, leading to fast capacity fading. However, the adverse effects of surface impurities can be eliminated by introducing a Lewis acid additive, which not only dissolves contaminants but also forms a stable electrode/electrolyte interphase film. This research provides insights into the degradation mechanism of nickel-rich materials and offers a viable strategy for self-repairing moderately degraded materials.

Summary: This study proposes a strategy of interface reconstruction for the anatase TiO2 cathode, which combines ultrathin carbon coating and oxygen vacancies, to achieve fast surface-redox pseudocapacitance charge storage mechanism. The reconstructed cathode/electrolyte interface promotes the kinetics of active cations and induces the less potential-dependent charge storage process, resulting in remarkable rate performance and long lifespan.

Summary: This study regulates the interfaces at both Zn anode and vanadium oxide cathode in aqueous batteries with a high donor number electrolyte additive. By introducing N-methylpyrrolidone (NMP) molecule to the ZnSO4 electrolyte, the researchers are able to protect the Zn anode from corrosion and achieve high coulombic efficiency of plating-stripping. The formation of cathode-electrolyte interface effectively suppresses vanadium dissolution and enhances the capacity retention over cycling.

Summary: Detecting unintentional islanding is crucial for ensuring personal safety and preventing equipment damage in microgrids. Most islanding detection techniques rely on monitoring deviations in frequency, voltage, current, and power. However, fluctuations within permissible limits defined by grid codes can render these methods ineffective, creating a non-detection zone (NDZ). This study surveys the benefits of different islanding detection techniques, calculating the NDZ sizes for common passive methods and comparing them with industry standards.

Summary: Nanomaterials have unique properties that make them highly attractive, and various solution fabrication methods have been developed for synthesizing metal and metal oxides nanoparticles. However, solid-state methods for obtaining nanomaterials are relatively scarce. This review discusses current solid-state methods and introduces a new general method for obtaining nanomaterials. By using macromolecular complexes as precursors, nanoparticles of metals and metallic oxides can be obtained via solid-state pyrolysis. The size and morphology of the nanoparticles depend on the polymer and metal arrangement. The paper also highlights the applications and challenges in this field.

Summary: High-temperature technologies like solid oxide cells (SOC) are being used for power-to-fuel and vice versa conversion, but durability and compatibility issues at high temperatures are still being addressed. Thus, there is a growing focus on optimizing the physical, mechanical, and chemical properties of SOC materials at lower temperatures. Finding suitable air electrodes remains a significant challenge. Lanthanide nickelates with Ruddlesden-Popper (RP) and perovskite structures are emerging alternatives due to their fast ion and electron transport, as well as flexible oxygen stoichiometry. This review aims to document the research and development status of RP nickelate air electrodes and compare their electrochemical performance.

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: 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.
