Summary: In this study, a simple in situ polymerization method of 1,3-dioxolane electrolytes was used to fabricate integrated solid-state lithium batteries. The key to achieving a high-performance battery with excellent interfacial contact among carbon nanotubes (CNTs), active materials, and electrolytes is the in situ polymerization and formation of solid-state dioxolane electrolytes on interconnected CNTs and active materials. These batteries demonstrated high energy density, amazing charge/discharge rate, and long cycle life, thanks to the low resistance of 4.5 omega (-1) and high lithium-ion diffusion efficiency of 2.5x10(-11) cm(2) s(-1).

Summary: Lithium metal batteries (LMBs) are known for their high energy density and low redox potential, but they face a major issue with lithium dendrites. Gel polymer electrolytes (GPEs) have emerged as a promising solution, thanks to their good interfacial compatibility, comparable ionic conductivity to liquid electrolytes, and improved interfacial tension. This review examines the mechanisms and advantages of GPEs in suppressing lithium dendrites, explores the relationship between GPEs and solid electrolyte interfaces (SEIs), and summarizes the effects of GPE preparation methods, plasticizer selections, polymer substrates, and additives on the SEI layer. The challenges and prospects of using GPEs and SEIs for dendrite suppression are also discussed.

Summary: Lithium batteries are highly efficient energy storage devices that have greatly impacted the development of electronic products, particularly electric vehicles. However, due to energy density limitations and safety concerns, traditional liquid lithium batteries are expected to be replaced by a new generation of energy storage devices in the future. All-solid-state lithium batteries, specifically sulfide all-solid-state lithium batteries, have gained significant attention and development in recent years due to their advantages in terms of ionic conductivity, mechanical ductility, and electrode interface contact. This review discusses the exceptional advantages and key challenges of sulfide all-solid-state lithium batteries, as well as proposes future directions for commercially viable batteries.

Summary: The development of solid-state batteries with considerable energy densities and favorable safety is highly promising. However, the challenge lies in developing solid-state batteries with higher energy density and more durable and stable cycle life to meet the demand for large-scale energy storage and the rapidly growing lithium battery market. Inorganic solid electrolytes (ISEs) and composite solid electrolytes (CSEs) are advantageous solid-state electrolytes but also face stability issues. Various improvement strategies, such as modified particle filling, electrolyte pore adjustment, electrolyte internal structure arrangement, and interface modification, have been proposed.

Summary: Polymer electrolytes with good flexibility and processability have potential applications in the battery field. To overcome the limitations of low ionic conductivity, narrow electrochemical window, and poor mechanical properties, a PVDF-HFP based composite electrolyte filled with lithium magnesium silicate was designed. The addition of lithium magnesium silicate disrupted the ordered arrangement of polymer chain segments and improved the electrochemical stability of the electrolyte membrane. With the addition of polyethylene membrane, the mechanical properties of the electrolyte membrane were enhanced. The modified PVDF-HFP based polymer composite electrolyte showed high ionic conductivity and lithium ion migration number, as well as improved oxidation potential and ability to suppress lithium dendrite growth.

Summary: The next generation of lithium batteries requires high energy density, which can be achieved by shifting from conventional intercalation-based anode (such as graphite) to lithium metal anode. However, the highly reactive nature of Li metal and the hostless deposition and stripping reactions hinder its practical use as an anode. The solid electrolyte interphase (SEI) plays a vital role in protecting the Li metal surface, but the SEI layers formed in different electrolyte systems have distinct properties, leading to different interfacial issues. This report compares the interfacial issues and provides different strategies for SEI modification to overcome these challenges.

Summary: Understanding the reaction mechanisms of aluminosilicate glass dissolution in aqueous environments is crucial for various technological applications. Molecular dynamics simulations were used to investigate the interfacial reactions of sodium aluminosilicate (NAS) glasses with different compositions. The results showed that coordination defects and non-bridging oxygens play a crucial role in the initial hydration reaction process. The formation of silanol and aluminol species, as well as ion-exchange reactions, were observed. The insights into the role of aluminum in these reactions can contribute to the design of more durable glasses.

Summary: Molecular dynamics simulations were used to study the structural and property changes in yttrium aluminosilicate glasses with varying silica contents. The results showed that the majority of Al3+ ions had a coordination number of four, with a small percentage in higher coordination states that increased with decreasing silica content. Significant concentrations of oxygen tri-clusters and small amounts of free oxygen were also observed, indicating a perturbed glass network structure. The glass transition temperatures were relatively unaffected by composition, consistent with experimental findings. A decrease in silica content resulted in an increase in Young's and bulk moduli, attributed to the strong Y-O bond and the formation of oxygen tri-clusters aggregating higher coordinated Al species. These findings were relevant to the optical and acoustic properties of YAS optical fibers with reduced nonlinearities.

Summary: Lithium aluminum germanium phosphate (LAGP) is a promising solid state electrolyte system for all solid state lithium ion batteries. This study investigates the nucleation and crystallization processes of LAGP through in situ synchrotron X-ray diffraction. The results show a compressive stress on the grains in the early stage of nucleation, increasing the solubility of aluminum in the nuclei. It is also found that aliovalent ion-substituted pure phase LAGP can be obtained at a significantly lower temperature through a two-step heat treatment.

Summary: A transparent Eu2+ doped fluorosilicate glass-ceramic has been developed to enhance the UV resistance and maintain the high photovoltaic performance of organic solar cells. Through theoretical design and experimental preparation, glass samples with immiscible fluoride and silicate glass sub-phases are created, and a thermal treatment is applied to grow EuSiO3 constrained BaF2:Eu nanocrystals. These nanocrystals enable spectral conversion with high optical transmittance and a relatively high quantum yield. Applying this spectral converting glass-ceramic to the organic active layer significantly improves the UV resistance without compromising the photovoltaic performance.

Summary: Although molecular dynamics (MD) simulation is a powerful tool for investigating the atomic-scale structures of complex materials, its reliable and accurate application to multi-component glass systems faces challenges due to limited force fields (FFs) and the complexity of chemical environments. This study demonstrates the feasibility of efficient and accurate large-scale density functional theory (DFT) calculations for multi-component glass systems. The evaluation of classical FFs based on the results of large-scale DFT calculations reveals low accuracy for non-bridging oxygen atoms, and differences in Si-O-Si angle distribution and electronic structure for X = Mg.

Summary: In this study, vanadium oxide xerogel samples were successfully synthesized through a liquid phase reaction and the interaction of films with water. The samples were thoroughly analyzed using X-ray diffraction and Raman spectroscopy, revealing the existence of two distinct phases. It was also discovered that previous misinterpretations regarding the high-pressure polymorph structure were due to the formation of a high-temperature phase. These findings highlight the potential for further refining and expanding the current structural models of vanadium oxide xerogel in future research efforts.
