Summary: Utilizing Spark Plasma Sintering technique to enhance the Li-ion conductivity of Li1+2xCaxZr2-x(PO4)(3) solid electrolytes resulted in high conductivity rhombohedral phase, especially at x = 0.1-0.3. The overlap of Ca and Zr elemental distributions indicates Ca incorporation into the lattice, with Ca-rich grain boundary phase observed in conventionally sintered samples. The technique is beneficial for achieving well-sintered pellets with high Li-ion conductivity.

Summary: A novel lithium-ion conductor with microporous channels was prepared using a hydrothermal-assisted sol-gel method, and composites with enhanced conductivity were obtained by infiltrating the prepared material. The interaction between microporous channels and dense lithium-ion conducting areas contributed to the increased conductivity of the composites, showing promising results for the preparation of solid lithium-ion conductors.

Summary: The drive towards all solid state lithium ion batteries necessitates the discovery of new synthesis methods for hybrid solid electrolytes that simultaneously optimize lithium ion conductivity and processability by chemically associating organic and inorganic components. In this study, a mechanochemical milling synthesis method is presented for the first time to produce an ambient processable hybrid lithium aluminum germanium phosphate (Li1.5Al0.5Ge1.5(PO4)3)/polyethylene glycol (PEG) solid electrolyte. Fourier transform infrared (FTIR) spectroscopy and thermogravimetric analysis (TGA) confirm that the mechanochemical milling procedure induces a condensation reaction between the ceramic and organic phases, resulting in the formation of water. Solid state nuclear magnetic resonance (NMR) spectroscopy verifies the bonding proximity between protons from the polymer or the water product to the Q2 metaphosphate sites of the glassy phase of the ceramic. This work establishes the viability of mechanochemical milling as a synthetic pathway for a class of promising ambient processable hybrid electrolytes.

Summary: In this study, garnet material with the composition of Li6.4Ga0.2La3Zr(2-x)YxO12(x = 0,0.1,0.3,0.5) was synthesized using the combustion sol-gel method. The phase evolution, microstructure, and ionic conductivity were analyzed. Yttrium was found to promote densification and grain growth, but excessive yttrium resulted in the formation of a secondary phase. The highest ionic conductivity was achieved in the Li6.4Ga0.2La3Zr1.7Y0.3O12 sample with a relative density of 96.6%. Lower sintering temperature and holding time were used compared to previous reports with similar densities and conductivities, thanks to the effectiveness of Ga/Y in promoting sintering and the good sinterability of the synthesized powders. This synthesis method has the potential for large-scale production due to its reduced energy and time requirements.

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: This study investigates the potential of sodium batteries as alternatives to lithium batteries, exploring the effects of sodium content and sintering temperature in solid electrolytes, as well as using natural substances and organic materials as pore-formers and freeze casting to achieve enhanced room temperature conductivity in porous ceramic electrolyte samples. Porous NASICON samples show an order of magnitude increase in conductivity compared to pore-free samples, making them a potential functional macroporous inorganic separator for sodium ion batteries.
