Summary: In this study, a simple in situ polymerization method of 1,3-dioxolane electrolytes was used to fabricate integrated solid-state lithium batteries. The key to achieving a high-performance battery with excellent interfacial contact among carbon nanotubes (CNTs), active materials, and electrolytes is the in situ polymerization and formation of solid-state dioxolane electrolytes on interconnected CNTs and active materials. These batteries demonstrated high energy density, amazing charge/discharge rate, and long cycle life, thanks to the low resistance of 4.5 omega (-1) and high lithium-ion diffusion efficiency of 2.5x10(-11) cm(2) s(-1).

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.
