Abstract

Uncontrollable dendrite growth and severe parasitic side reactions on Zn electrodes pose formidable challenges for the application of aqueous Zn-ion batteries. Herein, we engineered a biomimetic inorganic–organic protective layer composed of alginic acid and lithium magnesium silicate to enhance the stability and reversibility of the Zn electrode. This protective layer not only diminishes free water concentration near Zn surface but also creates negatively charged ion microchannels to transport Zn ions and modulate the solvation structure. Moreover, a robust Mg-SiO₂ interphase with high Young’s modulus and strong zincophilicity can be formed between the Zn electrode and the protective layer, facilitating uniform Zn deposition along Zn(002) planes. Consequently, this protective layer allows the Zn electrodes to achieve impressive cycling lifespan of 5500 h at 1 mA cm^–2/1 mAh cm^–2 with a Coulombic efficiency of 99.5% and delivers a remarkable cyclability of up to 8000 cycles in Zn||V₂O₅ full cells.

期刊介绍： ACS Energy Letters is a monthly journal that publishes papers reporting new scientific advances in energy research. The journal focuses on topics that are of interest to scientists working in the fundamental and applied sciences. Rapid publication is a central criterion for acceptance, and the journal is known for its quick publication times, with an average of 4-6 weeks from submission to web publication in As Soon As Publishable format. ACS Energy Letters is ranked as the number one journal in the Web of Science Electrochemistry category. It also ranks within the top 10 journals for Physical Chemistry, Energy & Fuels, and Nanoscience & Nanotechnology. The journal offers several types of articles, including Letters, Energy Express, Perspectives, Reviews, Editorials, Viewpoints and Energy Focus. Additionally, authors have the option to submit videos that summarize or support the information presented in a Perspective or Review article, which can be highlighted on the journal's website. ACS Energy Letters is abstracted and indexed in Chemical Abstracts Service/SciFinder, EBSCO-summon, PubMed, Web of Science, Scopus and Portico.
