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.

Modification of carbon nanofibers for boosting oxygen electrocatalysis

“…The rapid development of society and increasing energy demand in people's daily life have stimulated researchers to explore more efficient energy conversion and storage technologies. [1][2][3][4][5][6] During the search for advanced energy conversion and storage devices to alleviate the dependence on conventional fossil fuels, fuel cells, [7][8][9] water electrolysis, [10][11][12] and metal-air batteries [13][14][15][16] have attracted extensive attention due to their high efficiency and environmental friendliness. Oxygen electrochemical reactions such as the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER) are indispensable, and determine the cost and efficiency of these technologies.…”

Enhanced electrochemical performances based on ZnSnO3 microcubes functionalized in-doped carbon nanofibers as free-standing anode materials

“…However, the most widely employed traditional anode material, i.e., graphite, has a poor theoretical specific capacity (only 372 mA h g −1 ), which makes it difficult to satisfy the demands of LIBs of a high energy density and high reversible capacity. 4,5 Therefore, it is necessary to explore a novel electrode material for the purpose of effectively improving the electrochemical performance in terms of reversible capacity and operation life.…”

Atomic-interface strategy and N,O co-doping enable WS2 electrodes with ultrafast ion transport rate in sodium-ion batteries

“…[5][6][7][8] However, the large radius of Na + ($0.106 nm) endows anode materials with sluggish ionic-transport kinetics, thus resulting in poor fast-charging capability. 9,10 To solve this tricky problem, a multitude of anode materials with well-designed structures, such as metals, 11,12 metal suldes, 13 metal oxides, 14 hard carbon, 15,16 and graphene, 17 have been demonstrated with good rate performances. However, the anode materials possessing ultrafast Na + -storage capability, together with ultrahigh capacity and an ultralong working lifetime, are highly required for fastcharging SIBs, which still is a huge challenge up to now.…”
