Special Issue Information
Dear Colleagues,
The ever-increasing demand for electric portable devices and electric vehicles (EVs) calls for electrochemical energy conversion and storage devices that deliver higher energy-density outputs. However, the development of high-energy-density lithium-ion batteries (LIBs) is seriously limited by the disadvantages of currently existing electrolyte systems. Substituting the low theoretical specific capacity graphite anode in LIBs with lithium-metal, which has high theoretical specific capacity and low electrochemical potential, can effectively improve the energy density of lithium-metal batteries (LMBs). Nevertheless, the development of next-generation high-energy-density LMBs imposes higher requirements on the properties of almost every component (including cathodes, electrolytes, separators, and anodes) of LMBs. To further improve the energy density and lifespans of LMBs, further significant progress is needed in the widening and deepening of the scientific framework for lithium-metal batteries. This Special Issue invites original articles dedicated to the following topics: strategies for enhancing the structure stability of high-voltage cathodes; various efficient functional organic electrolytes which can enable suppressed battery decomposition and facilitate the formation of desirable solid electrolyte interfaces/cathode electrolyte interfaces (SEI/CEI); separators with improved physiochemical properties to reinforce the battery performances and/or safety; artificial SEI/CEI layers to suppress electrolyte decomposition; and metallic anode protecting technologies to suppress the formation of dendrites and improve the coulombic efficiency (CE) of batteries.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
