“…Subsequently, active polysulfides and fresh Li are consumed by side reactions, reducing coulomb efficiency (CE) and further diminishing the capacity of Li-S batteries. For this reason, researchers have proposed solutions in terms of ion distribution, deposition behavior etc., which are mainly divided into the following three types: (a) surface protection -a protective film with excellent mechanical properties is constructed on the surface of the lithium metal anode to prevent dendrites from piercing; (b) lithium-carrying framework -using nano-materials with regular morphology as the 'host' for metal lithium deposition to reduce the volume change on the negative electrode side; (c) solid electrolyte -this type of the electrolyte can effectively prevent dendrites from penetrating and has extremely high safety [155][156][157][158]. Relatively low electrical conductivity is desirable when choosing an appropriate scaffold/framework material to prevent direct Li deposition.…”

Lithium–sulfur (Li–S) batteries are considered as promising candidates for future-generation energy storage systems due to their prominent theoretical energy density. However, their application is still hindered by several critical issues, e.g., low conductivity of sulfur species, the shuttling effects of soluble lithium polysulfides, volumetric expansion, sluggish redox kinetics, and uncontrollable Li dendritic formation. Considerable research efforts have been devoted to breaking through the obstacles that are preventing Li–S batteries from realizing practical application. Recently, benefiting from the no additives/binders, buffer of volume change, high sulfur loading and suppress lithium dendrites, the nanoarray structures have emerged as efficient and durable electrodes in Li–S batteries. Herein, recent advances in design, synthesis and application of nanoarray structures in Li–S batteries have been reviewed. First, the multifunctional merits and typical synthetic strategies of employing nanoarray structure electrodes for Li–S batteries are outlined. Second, the applications of nanoarray structures in Li–S batteries are discussed comprehensively. Finally, the challenge and rational design of nanoarray structure for Li–S batteries are analyzed in depth, with the aim of providing promising orientations for commercialization of high-energy-density Li–S batteries.

Due to the ultrahigh theoretical specific capacity (3860 mAh g‐1) and low redox potential (‐3.04 V vs. standard hydrogen electrode), Lithium (Li) metal anode (LMA) received increasing attentions. However, notorious dendrite and volume expansion during the cycling process seriously hinder the development of high energy density Li metal batteries. Constructing three‐dimensional (3D) current collectors for Li can fundamentally solve the intrinsic drawback of hostless for Li. Therefore, this review systematically introduces the design and synthesis engineering and the current development status of different 3D collectors in recent years (the current collectors are divided into two major parts: metal‐based current collectors and carbon‐based current collectors). In the end, some perspectives of the future promotion for LMA application are also presented.

“…Rechargeable lithium-ion batteries (LIBs) have been previously considered as promising candidates for application in intermittent energy storage, due to their decent reversibility, high security, and superb energy efficiency. [6][7][8] However, LIBs, mostly based on the ion intercalation mechanism are now approaching their theoretical energy density of 300-350 W h kg À1 and can satisfy neither the large-scale energy storage scenario, [9][10][11] such as the power grids aforementioned, nor the prevailing electric vehicles. Hence, it is urgent to develop a powerful and reliable energy storage system on the way of exploiting and utilizing the natural energy resources with almost no carbon emission (Fig.…”
