Rational Design and Engineering of One‐Dimensional Hollow Nanostructures for Efficient Electrochemical Energy Storage

Abstract

The unique structural characteristics of one‐dimensional (1D) hollow nanostructures result in intriguing physicochemical properties and wide applications, especially for electrochemical energy storage applications. In this Minireview, we give an overview of recent developments in the rational design and engineering of various kinds of 1D hollow nanostructures with well‐designed architectures, structural/compositional complexity, controllable morphologies, and enhanced electrochemical properties for different kinds of electrochemical energy storage applications (i.e. lithium‐ion batteries, sodium‐ion batteries, lithium‐sulfur batteries, lithium‐selenium sulfur batteries, lithium metal anodes, metal‐air batteries, supercapacitors). We conclude with prospects on some critical challenges and possible future research directions in this field. It is anticipated that further innovative studies on the structural and compositional design of functional 1D nanostructured electrodes for energy storage applications will be stimulated.

1D confined materials synthesized via a coating method for thermal catalysis and energy storage applications

“…The synthesis methods of accurately trapping the guest materials in the channels of the 1D host and depositing them on the outer surface of the host are very important. [63][64][65][66] This is a prerequisite to clarify the connement effect by comparing the conned and supported material. However, when preparing conned/supported materials, the active materials always inevitably appear outside/inside these 1D nanomaterials.…”

Customizing Heterointerfaces in Multilevel Hollow Architecture Constructed by Magnetic Spindle Arrays Using the Polymerizing‐Etching Strategy for Boosting Microwave Absorption

“…[ 47 ] However, traditional methods to construct hollow structures usually involve time‐consuming and additional etching reagents to remove the templates. [ 48 , 49 , 50 ] And the internal cavity and distribution of heterogeneous interfaces are hard to control in hollow architectures. Therefore, it is necessary to develop a facile and efficient strategy to customize electromagnetic interfaces in hierarchically hollow structures, which plays the fundamental guide in heterointerface engineering for MA applications.…”

A Facile Pre-Lithiated Strategy towards High-Performance Li2Se-LiTiO2 Composite Cathode for Li-Se Batteries

“…However, the development of Li-Se batteries still faces many problems, such as notorious shuttle effect and volume expansion in Li + insert/extract processes, which cause the loss of active material and low Coulombic efficiency. Meanwhile, the intermediate products (polyselenides) dissolve in ether-based electrolyte and further migrate to the anode side, which will not only passive the surface of lithium metal anode, but also severely reduce the cyclic performance [ 22 , 23 , 24 , 25 , 26 , 27 ].…”
