Summary: The study investigates the impact of host material porosity on the performance of Li-S batteries using a sulfur-rich copolymer as the cathode active ingredient. Two types of porous CNF samples were designed to study the effects, and it was found that using microporous CNFs led to stable capacity over a larger number of cycles compared to mesoporous CNFs. The research highlights the significant role of cathode host porosity in battery performance, despite the positive effect of C-S bond formation in the active material.

Summary: By coating ordered mesoporous Mn2O3 (m-Mn2O3) and highly conductive Super P (SP) on polyethylene (PE) separators, we have designed a multifunctional composite separator to enhance the reversibility and cycling stability of lithium-sulfur batteries (LSBs). The m-Mn2O3 offers fast chemisorption of polysulfides dissolved in electrolyte, and the highly conductive SP physically mitigates the crossover of polysulfides and reversibly reutilizes them during cycling. In practice, the LSB cell assembled with the separator coated with m-Mn2O3 and SP delivers a high reversible capacity of 553 mAh g-1 at a current density of 0.5 C, even after 300 cycles.

Summary: The electrolyte-to-sulfur (E/S) ratio has a significant impact on the electrochemical performance of Lithium-Sulfur (Li-S) batteries. An optimal E/S ratio should balance the migration of active materials and the wetting of the active material. Low E/S ratios may result in capacity decay due to electrolyte depletion, while high E/S ratios may lead to dissolved lithium polysulfide species diffusing to the lithium anode surface.

Summary: In this study, the influence of gold nanoparticles (AuNPs) on the photoluminescence behavior of cadmium selenide (CdSe) quantum dots (QDs) confined in spatially separated soft nanoscale cylindrical domains was investigated. It was found that the presence of AuNPs can manipulate the photoluminescence intensity of CdSe QDs, with low fraction of AuNPs leading to enhancement and further increase causing quenching of the intensity. The interaction between energy transfer mechanisms and FRET/electron transfer processes between QDs and AuNPs could explain the observed phenomena.

Summary: This study explores the impact of functionalization and distribution of carbon nanotubes (CNTs) in polymer matrices or blends on the electromagnetic interference (EMI) shielding performance of nanocomposites. It is found that despite a decrease in electrical conductivity, ball-milled CNTs may not necessarily lead to a drastic decrease in shielding effectiveness. In addition to the compartmentalization of CNTs, the state, dispersion, and distribution of CNTs also play a significant role in determining the final properties of the composites.

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: 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.
