The focusing effects of MLAs are examined, and good agreement is presented between experiments and simulations. The photodegradation efficiency of organic pollutants in water is significantly enhanced by 5.1-fold, attributed to higher intensity at focal points of concave MLAs.

Among these methodologies, morphological optimization and carbon modification can warrant a stable operating voltage and prolong the cycling lifespan, which can be accessible by utilizing metal–organic frameworks as self-sacrificing templates. Herein, we conceptualize a strategy to in-situ construct N-doped carbon-coated LFP with Prussian blue analogues as the template, after which electrochemical tests extensively exploit the lithium storage capacity with 153.2 mAh g−1 after 500 cycles at 0.5 C. However, the capacity failure associated with the inevitable Li+ loss and destructed carbon layer provides sufficient room for the restoration of LFP after long-term cycling. Motivated by this, the cell performance of LFP/C after targeted restoration using the 3,4-dihydroxybenzonitrile dilithium salt is investigated, revealing a considerable recovered capacity due to the recuperative LFP crystal and uniform carbon layer with homogeneous N-distribution. The computational study also supports the feasibility of N-doped carbon layer in LFP modification.

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.\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture>\u0000 </div>\u0000 </figure>","PeriodicalId":93174,"journal":{"name":"EcoMat","volume":"5 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eom2.12416","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135426143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
