Article Abstract
Covalent organic frameworks (COFs) are a class of crystalline porous organic polymers with periodic networks that are constructed from small molecular units via covalent bonds, which have low densities, high porosity, large specific surface area, and ease of functionalization. The one-dimension nanochannels in COFs offer an effective means of transporting lithium ions while maintaining a stable structure over a wide range of temperatures. As a new category of ionic conductors, COFs exhibit unparalleled application potential in solid-state electrolytes. Here, we provide a comprehensive summary of recent applications and research progress for COFs in solid-state electrolytes of lithium metal batteries and discuss the possible development directions in the future. This review is expected to provide theoretical guidance for the design of high-performance solid-state electrolytes.

As a new generation of high-energy-density energy storage system, solid-state aluminum-ion batteries have attracted much attention. Nowadays polyethylene oxide (PEO)-based electrolytes have been initially applied to Lithium-ion batteries due to their flexible processing and good interfacial compatibility, their application in aluminum-ion batteries still faces problems. To overcome the limitations in aluminum-ion batteries-specifically, strong Al coordination suppressing ion dissociation, high room-temperature crystallinity, and inadequate mechanical strength-this study develops a blended polymer electrolyte (BPE) of polypropylene carbonate (PPC) and PEO.

Covalent organic frameworks (COFs) exhibit outstanding structural tunability, clearly defined ion pathways, and remarkable thermal/chemical stabilities, rendering them highly promising candidates for applications in solid-state electrolytes. However, it remains a challenge to develop a versatile method to incorporate both ionic groups and electron-withdrawing units into a single framework for effectively improving the lithium-ion conductivity. Herein, a series of novel [3+3] defective COFs is successfully synthesized featuring active amine/aldehyde anchoring sites for subsequent post-modification, and regulates the ion conductivity through elaborately tuning the anionic/cationic groups and weak/strong electron-withdrawing units.

Sulfide solid electrolytes (SEs) exhibit excellent ionic conductivity and good mechanical properties, but their poor air stability and solid-solid contact performance seriously hinder the wide application of sulfide all-solid-state batteries (ASSBs). Herein, this paper reviews the history and the major breakthroughs in the development of sulfide SEs. The theories of hard-soft-acid-base theory and glass structure theory, as well as several strategies to improve the chemical stability of sulfide SEs, are discussed emphatically.

We report the performance of solid-state ceramic supercapacitors (SSCs) based on a novel composite electrolyte comprising aluminum-doped lithium lanthanum titanate perovskite, LiLaTiAlO (Al-doped LLTO), and the ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIM BF). Rietveld refinement of X-ray diffraction data confirms the preservation of the tetragonal perovskite phase after Al substitution, indicating structural stability of the host lattice. X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy further corroborate the successful incorporation of Al without forming secondary phases.
