Abstract
Magnesium (Mg) anodes typically experience electrochemical passivation and dendrite formation with conventional electrolytes during cell storage and operation, which results in a rapid decline in cyclability and shortened lifespans. These concerns supposedly relate to the features of the Mg/electrolyte interface. Herein, we report that Mg(BH4)2-rich artificial hybrid interphase (AHI) fabricated on Mg by a simple cation replacement method effectively ensures electrochemical activity and nondendritic interface. This can be attributed to the synergy of fast Mg2+ transfer, high electronically insulating and structural stability, etc., of AHI, as revealed by experimental and computational findings. The symmetric cell presents a low-voltage polarization of 230 mV and prolonged cycling life of over 1300 h at 1 mA cm–2 in 0.5 M Mg[bis(trifluoromethanesulfonyl)imide (TFSI)]2/dimethoxyethane (DME) electrolyte. Meanwhile, the full cells paired with a Mo6S8 cathode at various rates with desirable stability are also achieved. Our work provides further insight into the design of a versatile non-MgCl2 artificial layer specialized for rechargeable Mg batteries.

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.
