Summary: All-solid-state lithium-ion batteries (ASSLIBs) are promising alternatives to conventional organic electrolyte-based batteries due to their higher safety and higher energy densities. This study investigates the use of composite electrolytes based on garnet-type materials for ASSLIBs and explores the effects of different compositions on ionic conductivity. The results show that the addition of succinonitrile can significantly improve the ionic conductivity.

Summary: Pyrochlore structure materials have unique crystal structure, electrical properties, and thermal stability, making them widely applicable in catalysis, nuclear waste encapsulation, sensors, and electronic devices. The ionic/electronic conductivity of these materials is crucial for their performance in solid oxide fuel cells, where factors like cation radius ratio, oxygen migration, vacancy formation, and dopant addition play significant roles in enhancing the conductivity. Research has shown that controlling these factors can improve the ion and electron transport properties of pyrochlore materials, ultimately leading to better performance in various applications.

Summary: One of the main challenges in oxide-based solid-state batteries is the densification of components to improve interfacial contact. The common method of co-sintering at high temperatures often leads to element inter-diffusion and degradation of cathode performance. This study evaluates the impact of different carbon grades on thermal response and chemical compatibility, showing that low surface area carbons are more suitable due to higher oxidation temperatures and lower reactivity.

Summary: This study investigates the influence of different electrolytes on the electrochemical performance of LSCF nanostructured electrodes. The results show that the ionic conductivity of the electrolyte has a significant impact on the polarization resistance of LSCF. Additionally, the rate-limiting steps for the oxygen reduction reaction (ORR) remain the same regardless of the electrolyte used.

Summary: With excellent energy densities and highly safe performance, solid-state lithium batteries (SSLBs) are regarded as promising energy storage devices. This review focuses on composite polymer electrolytes (CPEs), which are considered as one of the most promising candidates among all solid-state electrolytes. It discusses the two major obstacles affecting the development of CPEs, such as low ionic conductivity and high interfacial impedance, and provides feasible solutions for modifying CPEs through improving ion conduction mechanisms and electrode-electrolyte interface compatibility.

Summary: This study investigated the synthesis and analysis of lanthanum and tin pyrochlores electrolytes for solid oxide fuel cell (SOFC) applications. Ceramic samples with different compositions were synthesized and characterized. The doping of strontium had a positive effect on the structural and electrical properties, leading to an increase in ionic conductivity and a decrease in activation energy. The La2-xSrxSn2O7-delta electrolyte shows potential for intermediate temperature SOFC applications.

Summary: Inorganic-organic solid composite electrolytes (SCEs) have attracted wide attention due to their desirable properties, but their high polymer crystallinity hampers their ionic conductivity. This study utilized an unsupervised learning model to discover new SCEs with high conductivity based on limited experimental data. The findings not only shortened the screening period of SCEs, but also provided insights for the rapid discovery and design of solid-state battery materials.

Summary: The microstructure and electrochemical properties of Li1.125Ta0.875-xNbxZr0.125SiO5 ceramics prepared via the solid-phase reaction method were investigated. The conductivity of the ceramics increased and then decreased as the Nb doping concentration increased. Nb doping at 0.1875 mol facilitated the fusion and connection between grains, reducing the number of grain boundaries and increasing the conductivity. The structural distortion caused by the discrepancy in ionic radii of Ta5+ and Nb5+ allowed for more accommodation of Li ions and promoted Li+ diffusion, reducing the energy potential barrier for ion transport. The Li1.125Ta0.6875Nb0.1875Zr0.125SiO5 ceramic exhibited the highest conductivity, making it a potential candidate for all-solid-state batteries.

Summary: This study comprehensively investigates phase formations between different LSGM and LDC compositions and finds that only one combination does not result in additional phases. For other combinations, at least one additional phase is formed. It is suggested to use combinations that do not result in additional phases or to use LDC50 as a buffer layer or lower Sr content LSGM compositions as electrolytes in SOFC studies, as these combinations are likely to lead to better long-term performance.

Summary: Blending Al-doped Li7La3Zr2O12 in PEG-LiClO4 matrix enhances ionic conductivity and cycling reversibility. Garnet oxide fillers enlarge amorphous region and improve electrochemical stability, facilitating rapid Li+ migration. The empirical equation proposed simulates the relationship of fillers' mass and volume ratios in composite electrolyte membrane.

Summary: The water-gas-shift (WGS) reaction was studied on Cu catalysts supported on modified MgAl2O4 (MAO) support using Atomic Layer Deposition (ALD) method. The study found that Cu/MAO catalysts prepared by ALD exhibited higher activity, while Cu catalysts with ZnO, CeO2, and Mn2O3 films showed minimal differences in activity compared to Cu/MAO catalyst. Cu catalysts prepared on CoO films showed slightly lower activity.

Summary: A simple method for incorporating various catalytic metals into the pores of SBA-15 using vapor-phase infiltration is presented. The study utilized Atomic Layer Deposition (ALD) to expose metal precursors on SBA-15, forming monolayer films inside the mesopores. The size and loading of the metal particles were determined using characterization techniques. The effect of surface composition on catalytic performance was also investigated.
