Summary: Silicon is promising for lithium storage due to its high capacity and low working platform, but volume changes during cycling lead to material pulverization and electrode cracking. A robust binder is essential for maintaining Si electrode integrity, yet its role in modulating the chemical composition and spatial distribution of the SEI layer is often overlooked.

Summary: This study developed a novel inorganic binder, lithium metasilicate (LS), to address the issues of volume variation and limited Li+ diffusion ability in silicon anodes. The LS binder showed favorable compatibility with silicon nanoparticles (SiNPs) and improved the cycling stability and discharge capacity of the silicon anode through strong adhesion effect. The presence of Li+ transport channel within the LS binder further enhanced the Li+ diffusion ability in the silicon anode, resulting in higher discharge capacity.

Summary: LiNi0.8Mn0.1Co0.1O2||SiOx@graphite (NCM811||SiOx@G)-based lithium-ion batteries (LIBs) with the addition of p-tolyl isocyanate (PTI) and 4-fluorophenyl isocyanate (4-FI) in the electrolytes show improved low-temperature performance. Theoretical calculations and experimental results reveal that both PTI and 4-FI can generate stable SEI on the electrode surface and reduce the interfacial impedance. However, 4-FI is more effective in enhancing the low-temperature performance of the battery due to the optimization of F in the SEI membrane components.

Summary: Due to the urgent demand for high-energy-density lithium-ion batteries (LIBs), silicon (Si) with an ultrahigh capacity has gained wide attention. However, the practical application of Si is hindered by the large volume changes during cycling. In this study, a three-dimensional network binder composed of polyacrylic acid (PAA) and lysine (Lys) was constructed. The PAA/Lys binder exhibited strong adhesion to Si particles through hydrogen bonds and the cross-linked structure prevented irreversible slipping of PAA chains. The Si electrode using the PAA/Lys binder showed good cycling stability and high capacity retention, demonstrating the potential of using sustainable Si sources and environmentally friendly binders.

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.

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.
