In Situ Generated Zwitterionic Interface for Reversible Zn Anodes
Aqueous zinc ion batteries possess the merits of low cost, high safety, sustainability, and scalable production. However, the thorny issues of parasitic side reactions and zinc dendrite growth hinder their practical applications. Herein, an in situ generated polyzwitterionic polymeric interface {poly[3-(1-vinyl-3-imidazolio)propanesulfonate]} is constructed on the Zn anode through a simple yet efficient polymerization strategy. The designed polymeric interface not only accelerates the Zn2+ ion transport, repulses free SO42– anions, and facilitates the desolvation of Zn2+ ions but also replenishes Zn2+ ions at the electrode–electrolyte interface to mitigate the concentration gradient. Benefiting from such a unique design, Zn–Zn symmetric cells represent stable Zn plating/stripping for 7400 h at 0.5 mA cm–2. Moreover, the Zn–Cu asymmetric cells could deliver steady plating/stripping exceeding 6200 cycles with an average Coulombic efficiency of 99.60. This work highlights the potential of coordination interphase engineering in ensuring the stability of Zn anodes.

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.
