“…The symmetric cell using the prepared x PCMS‐ g ‐PEGMA/LN@Li demonstrated a very high dendrite suppression capability and volume change stability, as it operated stably for over 9100 h at a very high current density of 10 mA cm −2 . In other case, Kim et al 71 proposed a double‐layered protection layer consisting of a polyethylene oxide (PEO) layer and a cross‐linked polymer‐based layer on the Li metal surface. The bottom PEO layer has good binding characteristics with Li and high stability as it does not easily detach from Li during electrochemical reactions, and can suppress dendrite growth by creating uniform Li‐ion flux.…”

The lithium metal battery (LMB) is a promising energy storage platform with a distinctively high energy density in theory, outperforming even those of conventional Li‐ion batteries. In practice, however, the actual achievable energy density of LMBs is significantly limited due to the Li metal anode (LMA) being too thick (50–250 μm), and there are difficulties with expanding the highly reactive Li metal into large‐format cells due to safety concerns. Therefore, the recent focus of LMB research is headed toward the development of a thin and stable LMA. However, as the thickness of Li anode decreases (≤20 μm) and the absolute size of the battery cell increases, interfacial reactions on the Li surface become more active, potentially leading to fatal thermal runaway. In this regard, there is still much demand for the development of novel manufacturing technologies to overcome this issue and produce thin and stable Li metal. Considering these things, in this review, we initially examine the fundamentals regarding the deployment of LMAs using a number of essential metrics. Then, we introduce recent strategies employed for designing thin and stable Li anodes including host matrix architecturing, interface stabilization, and other advanced modifications. Finally, we propose future directions for the realization of practical LMBs and their potential applications in various battery systems, encompassing Na, K, and Zn‐based batteries. We anticipate that ultra‐thin and ultra‐stable metal anodes would find widespread utilization in secondary battery applications with high‐power requirements.image

“…Xu et al [116] fabricated a soft-rigid HASEI layer consisting of PVDF, hexafluoropropylene (HFP), and LiF. Kim et al [117] reported a double HASEI layer. The PEO and LiTFSI on the bottom layer and the polymer composed of phosphoric acid 2hydroxyethyl methacrylate ester on the top layer could dramatically protect the Li metal anode against the electrolytes.…”

Li metal anode has attracted extensive attention as the state‐of‐the‐art anode material for rechargeable batteries. It is defined as the ultimate anode material for the high theoretical specific capacity (3860 mAh g−1) and the lowest negative electrochemical potential (−3.04 V vs. Standard Hydrogen Electrode). However, the uncontrolled Li dendrites and the spontaneous side reactions between Li and electrolytes hinder its commercialization. To overcome these obstacles, the optimized solid electrolyte interphase (SEI) with excellent performance was proposed by the artificial method. The improved performance includes high stability, ionic conductivity, compactness, and flexibility. In this review, the strategies for artificial SEI engineering in liquid and solid electrolytes are summarized. To fabricate an ideal artificial SEI, the component, distribution, and structure should be fully and reasonably considered. This review will also provide perspectives for the SEI design and lay a foundation for the future research and development of Li metal batteries.

“…Uniform, ion-conductive, and chemically and mechanically stable protective layer coatings have been proven to effectively alleviate uncontrollable lithium dendrite growth and adapt to infinite volume changes in lithium metal. − Liu et al developed a coating process to fabricate nanoscale arrayed pores, and by confinement at the nanoscale, the Li + flux of the anode can be distributed, thereby suppressing Li dendrites to a certain extent and achieving uniform Li nucleation and growth. Compared with those bare electrodes, Li metal batteries with electrodes coated with nanochannels have better CE and longer cycle life, which exhibit superior stability.…”

Lithium metal anodes (LMAs) are considered one of the most promising anode materials for lithium metal batteries due to their high theoretical specific capacity (3860 mAh g −1 ) and low anode potential (−3.04 V compared to the standard hydrogen potential). However, the further application of lithium metal batteries is hindered by problems such as lithium dendrite growth and volume change of the anode. Fortunately, to address these issues in lithium metal batteries, various applications of nanomodification technologies have been proposed for lithium metal anodes, such as using nanomaterials and constructing nanostructures. These nanomodification technologies have standardized the plating/stripping behavior of lithium, significantly improving the electrochemical performance and lithium morphology of LMAs. This brief review systematically summarizes the latest research progress in LMA nanomodification technology to inhibit lithium dendrite growth. First, the problems of LMAs in practical applications are analyzed. Then, we summarize the forward-looking strategies and the latest research progress based on nanomaterials and nanostructures from the perspectives of current collectors, protection of the interface layer, separators, and all-solid-state lithium batteries. Finally, the future development of nanomodification technology for the protection of lithium metal batteries is summarized and prospected.
