Special Issue Information
Dear colleagues,
Traditional lithium-ion battery (LIB) technology possesses the “rocking-chair” flow of lithium ions between electrodes, and LIB cathode materials rely on the redox of transition metal ions (e.g., Fe3+/Fe2+ in LiFePO4). Despite being characteristic of superb reversibility and round-trip efficiencies, the further development of LIBs is limited by the inherent energy density and high cost. Therefore, it is urgent to develop disruptive energy systems with higher specific energies and lower costs. Researchers worldwide have been carrying out extensive work and developing a series of promising battery prototypes. One example is the use of lightweight oxygen as the cathode to establish the metal–oxygen battery system, which has two attractive advantages over LIBs: higher cathode capacities and an inexhaustible supply of oxygen from the air. Of course, researchers must overcome many significant challenges to fully utilize the potential of “proof-of-concept” LIB alternatives: battery safety is always a huge hurdle before practical applications, and the tradeoffs between the lifespan and achievable specific energy are often overwhelming. Accordingly, this Special Issue seeks to showcase research papers, short communications, and review articles that focus on the latest developments in new materials and approaches for the anodes, cathodes, and electrolytes of various emerging battery technologies.
We look forward to receiving your submissions!

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. Micromachines is an international peer-reviewed open access monthly 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 2100 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.
