锂金属电池(LMB)被认为是最有前景的下一代储能系统之一。然而,其实际应用存在极大的体积变化和锂枝晶的形成等重大挑战。为了应对这些挑战,引入炭材料的复合锂负极因其优异的化学和电化学稳定性以及在重复循环过程中的优异机械强度引起了极大关注。本文旨在全面概述锂化石墨(LiC_(6))的形成及其在锂沉积和剥离过程中在体相和界面区域的作用。在体相中,LiC_(6)表现出优异的亲锂性能,降低了锂成核的过电位并促进锂的均匀沉积。当在电极-电解质界面引入LiC_(6)时,它通过充当缓冲层来增强电极和电解质之间的接触,从而降低界面阻抗。最后,本文评述了锂碳复合负极发展的前景和挑战。

Secondary alteration of minerals in basalts of the Evevpenta gold occurrence(North Kamchatka， Russia) as indicators of ore forming processes

引用

地学前缘 2023年

作者： Anastasiya Sergeeva Pavel Zhegunov elena Skilskaia Mariya Nazarova elena Kartasheva Anna kuzmina Svetlana Moskaleva Olesya Zobenko Sharapat Kudaeva Ekaterina Plutakhina Kseniya Shishkanova Institute of Volcanology and Seismology， Far Eastern Branch， Russian Academy of Sciences

This paper describes in detail the mineralogy of the propylitic alteration of basalt host rocks in the Evevpenta gold occurrence in North Kamchatka. The vein system of the Evevpenta consists of quartz， adularia-quartz， quartz-carbonate veins， and， hydrothermal breccias hosted in dacite. Vein minerals are native gold， tellurides， sulfides， selenides， Au-Ag chlorides. The propylitic alteration occurs at a distance from the epithermal veins; however， it contains characteristic mineral assemblages useful for the reconstruction of an ore-formation environment. Four distinct hydrothermal alteration assemblages were recognized within the propylitic zone in this study: (1) Fluorapatite-fluorine-aluminous titanite， (2) Quartz-calcite-clinochlore， (3) Quartz-calcite-stilbite-montmorillonite， and 4. Calcite-mordenite. The earliest mineral assemblage was formed from an acid F-enriched hydrothermal fluid. The concentration of fluoride in fluid was 0.2–1.2 g/L， and temperature of about 550 ℃. The long-term interaction between the acid hydrothermal fluid and olivine basalt host rocks resulted in increasing pH to near neutral that caused chloritization process. The chloritization stage hydrothermal fluid was enriched in Fe and Mg with temperatures of about 175–210℃， chlorite I， and 120–140℃， chlorite II. The final stage of alteration consists of zeolite group minerals， which were precipitated from the hydrothermal fluid of pH ～ 9 and temperature >135℃. The high pH of the hydrothermal fluid could be explained by the presence of bicarbonates and carbonates and removal of the iron salt from the solution. Based on the alteration mineral assemblages of the propylitic zone， the physical and chemical conditions of the Evevpenta vein system are discussed. The transport of ore elements took place due to the formation of precious metal Cl–and OH–complexes at the stage of hydrothermal system formation with circulation of alkaline sodium chloride solutions. Chalcogens were also transferred by

俄罗斯北堪察加地区Evevpenta金矿床玄武岩主岩青磐岩化蚀变的矿物学组成,是以英安岩中的石英、冰长石-石英、石英-碳酸岩岩脉和热液角砾岩组成的脉系为特征。脉状矿物是天然金、碲化物、硫化物、硒化物和金-银氯化物。青磐岩化蚀变发生在距浅成热液脉较远的地方。然而,它的特征矿物组合对重建成矿环境有重要研究意义。在青磐岩化带内可识别出氟磷灰石-氟铝钛矿、石英-方解石-斜绿泥石、石英-方解石-硬石-蒙脱石、方解石-丝光沸石4种不同的热液蚀变组合。最早的矿物组合形成于酸性富F的热液中。热液流体中氟化物浓度为0.2~1.2 g/L,流体温度约550℃。酸性热液与橄榄玄武岩寄主岩石长期相互作用,导致pH升高至接近中性并发生绿泥石化作用。绿泥石化阶段热液富集Fe和Mg,温度约175~210℃时形成第1阶段绿泥石,120~140℃时形成第2阶段绿泥石。蚀变的最后阶段形成沸石群矿物,其在pH约为9、温度>135℃的热液中析出。热液流体的高pH值可能是由于碳酸氢盐和碳酸盐的存在以及溶液中铁盐的去除。根据青磐岩化带蚀变矿物组合特征,探讨了Evevpenta脉系形成的物理化学条件。在热液体系形成阶段,随着碱性氯化钠溶液的循环,贵金属Cl~-和OH~-络合物的形成导致了矿石元素的运移。高pH溶液也能转移硫。
