Summary: Lithium iron phosphate (LiFePO4, LFP) was investigated as an additive in the cathode of lithium-sulfur (Li-S) batteries, which showed improved sulfur utilization and cycling performance. LFP was found to attract polysulfides, reducing the shuttle effect. Postmortem characterization revealed dynamic reconstruction of LFP during cycling, which could have contributed to the observed performance.

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: 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).
