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 introducing a functional organic molecule to couple with polysulfide intermediates, a fast internal cycle of promotors has been created to promote the slow external cycle of sulfur conversions. This strategy not only greatly improves the sulfur-electrode process kinetics and eliminates the shuttle effect, but also modifies the morphology of the final discharge product into a uniform covering film, leading to excellent rate performance and cycling stability of lithium-sulfur batteries.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
