Molecular‐Level Encapsulation Strategy: Host–Guest‐Inclusion‐Complex‐Derived Carbon‐Encapsulated Nanocomposites for High Performance Lithium‐Ion Storage

Abstract

and 3D walnut structure. [15,16] Then, how to encapsulate nanoparticles with smaller particle size inside porous carbon material dispersion is a key technique problem. Compared with encapsulation of nanoparticles in synthesized porous carbon materials, the bottom-up synthesis and in situ assembly of carbonencapsulated nanomaterials are more flexible and attractive.

Boosting the Kinetics and Stability of Zn Anodes in Aqueous Electrolytes with Supramolecular Cyclodextrin Additives

“…The exterior of the cavity is highly polar due to the bristling hydroxyl groups, while the interior is nonpolar with lipophilic character . This structure gives CD molecules a relatively hydrophobic central cavity and a hydrophilic outer surface, providing enzyme-like properties for molecular recognition and capture . Hence, we envision that CD could regulate the electrodeposition dynamics and complex interfacial reactions, which torture metal electrodes in electrochemical devices such as aqueous Zn batteries (AZBs). − …”

“…22 This structure gives CD molecules a relatively hydrophobic central cavity and a hydrophilic outer surface, providing enzyme-like properties for molecular recognition and capture. 23 Hence, we envision that CD could regulate the electrodeposition dynamics and complex interfacial reactions, which torture metal electrodes in electrochemical devices such as aqueous Zn batteries (AZBs). 24−26 AZB is a promising technology for large-scale energy storage because of high safety, material abundance, and inherent merits of metallic Zn including high theoretical capacity (820 mA h g −1 ) and low redox potential (−0.76 V vs standard hydrogen electrode).…”

Host/Guest Nanostructured Photoanodes Integrated with Targeted Enhancement Strategies for Photoelectrochemical Water Splitting

“…Host/guest architectures are not only applicable for PEC water splitting, but also for electrocatalyst, [138] solar cell, [139] and ion battery. [140,141] Based on the review of various nanostructured host scaffolds, an ideal host scaffold should fulfill the following requirements: low cost, high chemical stability, superior electrical conductivity, and periodic architectures. With the help of host scaffolds, the optical and electrical properties of various guest materials can be improved simply in constructing host/guest structures.…”
