Summary: Fast charging is crucial for next-generation energy storage devices, but it brings increased security risks and capacity attenuation. To overcome these issues, researchers have developed a novel gel polymer electrolyte (GPE) based on polyvinylene carbonate, poly (ethylene oxide), poly (vinylidene fluoride-co-hexafluor-opropylene), and ionic liquid modified carbon nanotubes (IL-CNTs). This GPE exhibits improved lithium ion transportation, resulting in enhanced ionic conductivity and lithium-ion transference number. The GPE also demonstrates a wide electrochemical window and good cycle life, making it a valuable guideline for designing fast-charging GPEs.

Summary: A non-swelling, solvent-adaptive polymer gel was designed as a quasi-solid state electrolyte for lithium batteries, maintaining high ionic conductivity and mechanical strength. The gel electrolyte showed excellent performance in electrolyte salt dissociation and dendrite inhibition, cycling for over 500 hours under high current density and demonstrating a reversible specific capacity of 70 mAh g(-1) after 300 cycles when paired with LiFePO4 cathode. The rational design of solvophilic/solvophobic zwitterionic elastomers provides guidance for engineering quasi-solid state electrolytes with broad applications in flexible devices.

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.
