“…A unique capped 3D framework consisted of a lithiphilic matrix with PAA coating has been fabricated for constructing stable artificial SEI on 3D high lithium‐reservoir host. [ 168 ] In this case, the in situ formed high‐ion conductive LiPAA can facilitate Li + transfer inside the skeleton rather than depositing on the surface, bringing out the dendrite‐free lithium anode. Thus, the advanced PAA@Li matrix demonstrates excellent cyclic stability for 350 h at both high current density of 5 mA cm −2 and high cycling capacity of 5 mA h cm −2 with near‐zero volume change.…”

Prelithiation/presodiation techniques are regarded as indispensable procedures in electrochemical energy storage (EES) systems, which can effectively compensate irreversible capacity loss, raise working voltage, and increase Li+/Na+ concentration in the electrolyte. Various prelithiation/presodiation methods have been successfully exploited and a revolutionary impact has been achieved through the utilization of prelithiation/presodiation techniques. It is well acknowledged that different prelithiation/presodiation strategies possess their own specific mechanisms, which play vital roles in the advancement of EES systems. However, there has rarely been systematical reviews about the concept and progress of prelithiation/presodiation techniques. Hence, in this review various prelithiation/presodiation approaches are comprehensively analyzed and summarized, and in‐depth prelithiation/presodiation behaviors and other innovative applications (including optimization of separators, amelioration of binders, regeneration of spent batteries) are discussed in detail. Finally, suggested future directions of prelithiation/presodiation techniques are proposed and it is expected that these prelithiation/presodiation techniques could provide guidance for construction of advanced EES systems and propel the commercialization process with a focus on safety considerations.

“…The artificial SEI layers are supposed to not only prevent the side reactions with electrolytes and soluble polysulfides, but also induce uniform Li stripping/plating. Ideally, the artificial SEI layers should possess the following properties: (1) [297][298][299][300][301][302][303][304] ; organic artificial SEI layers, such as lithiated Nafion, LiPAA, PI, PEO, PDMS, b-PVDF, and P(S-DVB) [305][306][307][308][309][310][311][312] ; composite artificial SEI layers, such as SiO 2 @PMMA, PVDF-HFP/LiF, PEDOT-co-PEG/AlF 3 , and Li 1.5 Al 0.5 Ge 1.5 (PO 4 ) 3 / PVDF. [313][314][315][316] Different sorts of artificial SEI layers have specific advantages and disadvantages in protecting Li metal anodes.…”

With the merits of low cost, abundant resources, environment friendliness, and high energy density, the Li-S battery is recognized as a promising alternative to the Li ion battery and is anticipated to play an important role in high-energy-density electrochemical storage systems. In this review, we first review the development process of Li-S batteries and briefly introduce the working principle of Li-S batteries. The scientific problems existing in the Li-S batteries, such as sulfur cathode, separator, electrolyte, and Li anode, and the corresponding countermeasures, are then summarized. Subsequently, main research advancements of Li-S batteries are comprehensively reviewed, and the critical concerns about commercialization of Li-S batteries are discussed. Finally, we give our perspectives on the development of high-performance Li-S batteries. We hope this review can provide the timely and comprehensive information on the future research direction of Li-S batteries and offer the guidance for material design and structure optimization of Li-S batteries.

“…Feng et al constructed a stable artificial SEI layer by directly coating PAA layer on the surface of a 3D Li framework (Figure 6(C)). 83 The in situ formed high‐ion conductive LiPAA effectively restrains Li dendrites by facilitating Li + transmission rather than deposition. As a result, PAA@Li matrix exhibits near‐zero volume change upon the cycling and intensive battery performance with excellent cycling stability for 350 h at both high areal capacity (5 mAh cm −2 ) and high current density (5 mA cm −2 ).…”

Lithium metal batteries (LMBs) are considered the most promising energy storage devices for applications such as electrical vehicles owing to its tremendous theoretical capacity (3860 mAh g−1). However, the serious safety issues and poor cycling performance caused by the dendritic crystal growth during deposition are concerned for any rechargeable batteries with a lithium metal anode. To make widespread adoption a possibility, considerable efforts have been devoted to suppressing lithium (Li) dendrite growth. In this review, the recent strategies to developing dendrite free Li anode, including constructing an artificial solid electrolyte interface, current collector modification, separator film improvement, and electrolyte additive, are summarized. The merits and shortcomings for different strategies are reviewed and a general summary and perspective on the next generation rechargeable batteries are presented.
