Emerging natural clay-based materials for stable and dendrite-free lithium metal anodes: A review

Chinese Chemical Letters 2025年第2期36卷 161-172页

作者： Haobo Wang Fei Wang Yong Liu Zhongxiu Liu Yingjie Miao Wanhong Zhang Guangxin Wang Jiangtao Ji Qiaobao Zhang School of Materials Science and Engineering Provincial and Ministerial Co-construction of Collaborative Innovation Center for Non-ferrous Metal new Materials and Advanced Processing Technology Henan University of Science and Technology Faculty of Engineering Huanghe Science and Technology University Henan Key Laboratory of Non-Ferrous Materials Science & Processing Technology Henan University of Science and Technology College of Agricultural Equipment Engineering Henan University of Science and Technology State Key Laboratory of Physical Chemistry of Solid Surfaces College of Materials Xiamen University

Lithium metal is one of the most promising anodes for lithium batteries because of their high theoretical specific capacity and the low electrochemical potential. However, the commercialization of lithium metal anodes(LMAs) is facing significant obstacles, such as uncontrolled lithium dendrite growth and unstable solid electrolyte interface, leading to inferior Coulombic efficiency, unsatisfactory cycling stability and even serious safety issues. Introducing low-cost natural clay-based materials(NCBMs) in LMAs is deemed as one of the most effective methods to solve aforementioned issues. These NCBMs have received considerable attention for stabilizing LMAs due to their unique structure, large specific surface areas, abundant surface groups, high mechanical strength, excellent thermal stability, and environmental friendliness. Considering the rapidly growing research enthusiasm for this topic in the last several years, here, we review the recent progress on the application of NCBMs in stable and dendrite-free *** different structures and modification methods of natural clays are first summarized. In addition, the relationship between their modification methods and nano/microstructures, as well as their impact on the electrochemical properties of LMAs are systematically discussed. Finally, the current challenges and opportunities for application of NCBMs in stable LMAs are also proposed to facilitate their further development.

Transcription termination is a crucial step in gene expression and is pivotal for the accurate completion of mRNA *** bacteria and eukaryotes employ distinct regulatory mechanisms for this process, intriguing parallels exist. In bacteria, transcription termination occurs via two primary mechanisms:the intrinsic (Rho-independent) and the Rho-dependent pathways. The intrinsic pathway hinges on the formation of a hairpin loop by specific RNA sequences and the following poly(U) sequence, which prompts the release of the nascent RNA and the detachment of RNA polymerase(RNAP) from DNA (You et al., 2023).
