Summary: The study demonstrates that incorporating a pyrrolidinium cation with an oligo(ethylene oxide) substituent in SPEs can enhance lithium-ion transport speed. This not only accelerates the conduction modes of PEO, but also enables new conduction modes associated with the solvation of lithium by a single IL cation, leading to improved performance on lithium-metal polymer batteries.

Summary: In this study, hybrid gel polymer electrolytes (HGPEs) composed of PMMA-PLA with LiTFSI were investigated. The addition of LiTFSI decreased the glass transition temperature of HGPEs and enhanced the amorphous phase, resulting in increased ionic conductivity. The dielectric response approach revealed that the ion dissociation and transport properties of the PMMA-PLA-LiTFSI systems followed the trend of ionic conductivity.

Summary: Solid-state batteries can provide high energy density and safety, while polymer electrolytes face challenges due to slow ion kinetics and low selective transport of Li+. Metal-organic frameworks (MOFs) are proposed as fillers for solid-state electrolytes, but developing functionalized MOFs and understanding their role in ion transfer is difficult. This study demonstrates that functional group regulation in MOFs can effectively control charge distribution and limit anion movement, leading to improved performance in composite electrolytes for high-performance solid-state batteries.

Summary: Lithium salts with low coordinating anions such as bis(trifluoromethanesulfonyl)imide (TFSI) have been widely used in polyethylene oxide (PEO)-based dry polymer electrolytes. Recent research has shown that plasticizing PEO with TFSI-based ionic liquids (ILs) can increase conductivity and Li+ diffusivity. However, the Li+ transport mechanism remains unchanged and is limited by the polymer host matrix. This study suggests a new paradigm of using more coordinating anions such as trifluoromethanesulfonyl-N-cyanoamide (TFSAM) to enhance Li+ transport and achieve higher Li+ transference number.

Summary: The relationship between formation procedure and interfacial characteristics of electrodes in sodium-ion batteries is crucial for cell performance. We successfully shortened the formation time and improved the cycling performance of the sodium-ion half cell through optimized formation protocols in superconcentrated ionic liquid electrolytes. Our findings show that high C-rate formation contributes to a highly conductive and thinner solid-electrolyte interphase (SEI) layer, facilitating Na+ diffusion kinetics. This work provides a cost-effective and time efficient formation protocol for NIBs.

Summary: In order to utilize the advantages of high energy density lithium-metal batteries, their cycle life and safety need to be improved. External compression has been shown to enhance the performance of these batteries by reducing dendrite growth and improving lithium deposition morphology. This study investigates the behavior of high-capacity Li||LFP pouch cells in pyrrolidinium-based ionic liquid electrolytes under different levels of compression and discusses the mechanisms that affect the cell performance and failure. The results indicate that higher compression leads to more uniform and less dendritic lithium deposition.

Summary: Ion transport in composite electrodes is crucial for the performance of lithium-metal batteries, and the use of ionic conducting polymers as binders has been suggested. In this study, two poly(ionic liquid) polymers were analyzed as binders in LiFePO4 cathodes, and PMTFSI-Li showed the best performance with high specific capacity and long lifespan. Surprisingly, the presence of ionic binders also affected the lithium metal deposition morphology, leading to a more homogeneous plating and mitigating mossy lithium growth.
