“…Other than proton conduction, Kim and co‐workers also reported a new type of solid lithium‐ion conducting electrolyte by incorporating Li + ions into a 25 ‐based guest‐free COM, which displayed high Li + ion conductivity (about 10 −4 S cm −1 ) and high cationic transference number . Additionally, the solid electrolytes displayed thermally stable even after several temperature cycles.…”

macrocycles. They have been also employed to modify the surface properties of metal nanoparticles via noncovalent host−guest interactions, [31] covering their applications in drug delivery, [32] highly sensitive sensors, [33] selective catalysis, [34] and so on.In addition to their intensive applications based on their host−guest chemistry, macrocycles have also been used as building blocks to construct solid materials including porous organic polymers (POPs), [35,36] metal-organic frameworks (MOFs), [37][38][39][40][41][42][43] and crystalline organic materials (COMs). [44][45][46][47][48][49][50][51][52][53][54][55][56][57] Particular attention should be paid to COMs, a class of organic materials featuring facile preparation, high crystallinity, structural diversity, chemical stability, solution-processability, etc. [58][59][60][61][62][63][64][65][66][67][68][69][70] Different from MOFs that are composed of both inorganic (metal ions) and organic species (organic ligands) through coordination, COMs refer to a kind of crystalline materials composed of pure organics connected by either covalent or noncovalent bonds. [71][72][73] For COMs connected by noncovalent bonds, the typical materials are organic molecular crystals with intriguing properties such as semiconductor, [53] porosity, [68] etc. Owing to the inefficient packing of organic building blocks in the crystal state, some molecular crystals display extrinsic porosity, which are often termed as hydrogen-bonded organic frameworks (HOFs) [74,75] or supramolecular organic frameworks (SOFs). [76][77][78][79][80] For COMs connected by covalent bonds, typical materials are crystalline covalent organic frameworks (COFs), which were firstly reported in 2005 by Yaghi and co-workers [44] Benefitting from rigid chemical bonds and building blocks, COFs show permanent and well-ordered porosity. [45][46][47][48] Supramolecular-macrocycle-based COMs, a class of COMs with macrocycles as the main building blocks, have drawn particular attention in recent years. According to their components, supramolecular-macrocycle-based COMs can be classified into two main categories, the ones composed of pure macrocycles and the others consisting of macrocycles and other simple organic building blocks. Owing to their prefabricated cavities of a certain type, some of macrocycle-based COMs exhibit intrinsic microporosity for guest adsorption in the solid state. On the other hand, the extrinsic porosity of some macrocyclebased COMs may form due to the inefficient packing of these rigid macrocyclic molecules in the crystalline state. In certain circumstances, both intrinsic and extrinsic microporosity can be created in a single lattice of a certain COM, thus leading to Supramolecular macrocycles are well known as guest receptors in supramolecular chemistry, especially host−guest chemistry. In addition to their wide applications in host−guest chemistry and related areas, macrocycles have also been employed to construct crystalline organic materials (COMs) owing to their particular structur...

Conventional liquid electrolytes for lithium batteries usually suffer from irreversible decomposition and safety concerns. Solid state electrolytes (SSEs) have been considered as the key for advanced lithium batteries with improved energy density and safety, whereas challenges remain for polymer and inorganic SSEs. Recently, hybrid solid-state electrolytes (HSSEs) that integrate the merits of different electrolyte systems have been under intensive study. Herein, we summarize the recent progress of HSSEs with different compositions and structures. The design principle of each type of HSSEs are discussed, as well as their ionic conducting mechanism, electrochemical performance and effects of compositional/structural control. Finally, challenges and perspectives are provided for the future development of HSSEs and solid-state lithium batteries.

Creating Lithium‐Ion Electrolytes with Biomimetic Ionic Channels in Metal–Organic Frameworks

et al. 2018

View full text Add to dashboard Cite

Solid-state electrolytes are the key to the development of lithium-based batteries with dramatically improved energy density and safety. Inspired by ionic channels in biological systems, a novel class of pseudo solid-state electrolytes with biomimetic ionic channels is reported herein. This is achieved by complexing the anions of an electrolyte to the open metal sites of metal-organic frameworks (MOFs), which transforms the MOF scaffolds into ionic-channel analogs with lithium-ion conduction and low activation energy. This work suggests the emergence of a new class of pseudo solid-state lithium-ion conducting electrolytes.
