Summary: This study investigates the stability of the lithium metal-polymer electrolyte interface and reveals the formation of a passivating solid electrolyte interphase (SEI) layer at the working electrode when in contact with the solid polymer electrolyte. The thickness of the SEI layer increases with temperature. The chemical reaction mechanism involving the reductive cleavage of polymer molecules by lithium atoms is proposed based on spectroscopy data.

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: Solid polymer electrolytes based on dry poly(ethylene oxide) offer stability, mechanical properties, and flexibility for solid-state lithium batteries. Optimizing ionic conductivity involves understanding the relationship between the electrolyte's nature and architecture and the in-plane ionic transport properties. Different local mechanisms contribute to ionic transport, and distinguishing cationic and anionic mechanisms is necessary. This study determines the in-plane ionic conductivities, transference numbers, and diffusion coefficients of various SPEs and explores their hindered anionic transport.

Summary: A stable solid electrolyte interphase (SEI) layer at the interface of lithium metal and polyethylene oxide (PEO) electrolyte has been successfully engineered by incorporating phosphazene molecules. The phosphazene-solid polymer electrolyte (P-SPE) exhibits improved long-term stability against Li metal anode compared to non-modified SPE. Analysis using cryogenic transmission electron microscopy (cryo-TEM) and X-ray photon spectroscopy (XPS) identified Li3N, LiF, Li3P, and Li3PO4 nanocrystals in the SEI layer. Density function theory (DFT) and ab-initio molecular dynamic (AIMD) calculations further reveal the crucial role of phosphazene-modified SEI in enhancing electrochemical performance. This study offers a promising approach towards engineering a stable and ion-conductive Li|polymer electrolyte interface for long lifespan Li metal batteries (LMBs).

Summary: Incorporating Ni3B2O3 (NBO) nanorods into polyethylene oxide (PEO)-based solid polymer electrolyte (SPE) enhances ionic conductivity and enables high-performance lithium batteries at lower temperatures. The improved properties are attributed to decreased crystallinity, increased PEO chain mobility, enhanced lithium salt dissociation, and the creation of a lithium ion migrating pathway between PEO and NBO nanorods.
