The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries(AZIBs). These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose(Xylo) molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn^(2+)ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AZIBs.

人类起源及演化与地球系统环境演化相互关联的科学研究不仅是传统第四纪研究的关键内容之一，也是当今宜居地球研究的首要问题。文章回顾了黄土高原及邻近地区第四纪地层中发现的重要古人类遗存(包括古人类化石和旧石器)的主要成就，阐述了前人提出的“黄土石器工业”和“黄土地质考古带”研究思路的萌生和发展历程，介绍了学者们运用黄土-古土壤序列对第四纪不同类型沉积物中埋藏的古人类遗存研究的概况。在此基础上，根据前人的大量资料以及笔者自身数十年积累的第一手调查研究数据，提出了一种新的科学思路：针对“全球变化”研究中的薄弱环节，运用独一无二的中国黄土连续序列的“地圈”优势，去寻找“生物圈”古人类活动的连续“序列性”踪迹，研究古气候古环境演化对古人类生存环境的制约及其反馈等重大科学问题。以新的思路和科学问题为宗旨，运用黄土-古土壤序列标准年代框架标尺，以蓝田地区上陈、公王岭、陈家窝、吉家湾-甘峪-刁寨剖面的含石器或古人类化石的26个黄土-古土壤组合旋回(其中包括21个古土壤层和15个黄土层)为基础数据，初步构建了一个年代大约2.12～0.01 Ma B. P.的较高分辨率的古人类古文化演化序列——“黄土-古土壤-古人类遗存序列”框架，期望为人类演化和黄土环境研究拓展新路。
