Summary: In this study, the SEI on composite Si-Gr anodes was characterized using multi-modal characterization techniques to reveal the relationship between SEI chemical composition and structure with its functional properties. By combining multiple analysis methods, a comprehensive understanding of the SEI was obtained. The study found that the SEI has a bilayer structure and a direct correlation between elemental Li and F, suggesting that most Li in the SEI exists as lithium fluoride (LiF). Furthermore, there is an inverse relationship between lithium carbonate and LiF concentration in the SEI, providing insight into the detailed chemistry of SEI formation and evolution.

Summary: In this study, binder-free nanocluster Cr-doped NiO thin film electrodes were developed on flexible stainless-steel foils using a one-step co-sputtering technique. The unique nanocluster structure of the electrodes resulted in reduced ion diffusion length, improved charge transport, and increased accessibility of ions onto the active surface area. The electrodes exhibited a high areal capacitance of 429 mF cm-2 (251 mC cm-2) in a 2 M KOH aqueous electrolyte. The developed asymmetric coin cell supercapacitors demonstrated exceptional cycling stability even after 5,000 cycles and good electrochemical performance with minimal capacitance fading after 720 hours of aging test.

Summary: This study investigates the effect of fluorinated phosphazene compounds as electrolyte additives on the formation of the solid electrolyte interphase (SEI) in silicon oxide (SiOx)-based lithium-ion batteries. The results show that the dual-additive approach using fluoroethylene carbonate and hexafluorocyclotriphosphazene-derivatives (HFPN) in state-of-the-art electrolytes leads to synergistic effects, enhancing the electrochemical performance and stabilizing the electrolyte. Furthermore, using HFPN derivatives as an additive compound suppresses the decomposition of the electrolyte. This study is of great significance for improving the performance and practical application of lithium-ion batteries.

The specific heat capacity was determined using differential scanning calorimetry, while a novel method of numerical analysis using a thermal camera was investigated for measuring thermal diffusivity and conductivity. The results showed that the thermal conductivity parallel to the fibers of a non-crimp stitch bonded fabric matched well with the theoretical value, while voids in woven fabrics led to reduced transverse thermal conductivity.

Summary: The main challenge in lithium sulphur (Li-S) batteries is the shuttling of lithium polysulphides (LiPSs) caused by the rapid LiPSs migration to the anode and the slow reaction kinetics in the chain of LiPSs conversion. In this study, the affinity of 1T-MoS2 substrates towards LiPSs and their electrocatalytic effects were examined. The findings suggest that a combination of 1T-MoS2 regions, without or with one and two sulphur vacancies, can improve Li-S battery performance.

Summary: A major challenge in simulating Li-S batteries is that the electrochemical reaction parameters depend on microstructure and cannot be used in material design. This study fits the parameters using a continuum model that considers pore size distribution and tortuosity of cathode and separator. The redox reactions take place in the electrolyte solution rather than in the solid phase. The fitting is conducted based on experimental data of a cyclic voltammetry cycle and UV-vis spectroscopy.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
