Summary: The Li+ conductivity of Li7La3Zr2O12 (LLZO) solid electrolytes was optimized by controlling the addition of the dopant (Al) into the crystal structure. A critical dopant concentration of 0.18 mol pfu was required to stabilize the cubic phase and achieve the maximum ionic conductivity of 5.54 x 10-4 S/cm. The enhanced conductivity was achieved by accurately controlling the vacancy density at the active Li octahedral sites.

Summary: LiPON films have been a major focus in Li-ion micro-batteries for low power applications, and understanding the relationship between composition, processing parameters and ionic conductivity has been a challenge for the materials community for the past three decades. A general model is proposed in this study to calculate the ionic conductivity of LiPON solid electrolytes for any composition. The model is based on the fundamental laws of chemical equilibrium and has been successfully used to predict the formation of different oxynitride compounds and their corresponding ionic conductivities.

Summary: Composite solid electrolytes are crucial for all-solid-state lithium batteries, which are considered the next-generation energy storage devices. Numerous studies have shown that fillers in composite solid electrolytes can improve ion transport behavior by optimizing the ion transport path. The performance is closely related to filler structure and its interaction with other electrolyte components. This review focuses on dimensional design of fillers, as well as ion transport mechanism and filler-electrolyte interaction in advanced composite solid electrolytes. Strategies for designing composite solid electrolytes with high room temperature ionic conductivity are summarized to assist research for high-performance composite solid electrolytes.

Summary: This paper investigates the synergistic effect of the sol and intermediate layer on the performance of YSZ nanofiltration membranes. It was found that the performance of YSZ membranes strongly depends on the sol concentration and the pore size of the intermediate layer. Maintaining compatibility between the sol and intermediate layer is essential for fabricating high-performance NF membranes.

Summary: Lithium zirconium phosphate (LiZr2P3O12) thin films were prepared using a chemical solution deposition approach at temperatures between 700°C and 775°C, with post-annealing significantly affecting the crystallinity, grain size, and ion conductivity properties of the films. Single high-temperature annealing improved ion conductivity, while per-layer annealing showed a more complex effect with an initial increase followed by a decrease in ion conductivity. These results suggest that different post-deposition processing methods can greatly influence the ion conducting properties of LiZr2P3O12 thin films.
