Special Issue Information
Dear Colleagues,
Metal oxide cathodes (e.g., LiCoO2, LiFePO4, and high-entropy oxides) are critical for next-generation rechargeable metal batteries due to their high theoretical capacity, stability, and cost-effectiveness. However, metal oxide cathodes face critical challenges, such as structural degradation during cycling, sluggish ion diffusion kinetics, and interfacial side reactions with electrolytes, which collectively limit their energy density, rate capability, and long-term stability. This Special Issue aligns with Metals' scope by addressing these issues through atomic-to-macro scale structural control—including lattice doping, surface modification, and bulk architecture design—to enhance electrochemical performance. Fundamental studies on failure mechanisms and applied research on scalable solutions are equally encouraged.
We invite contributions exploring innovative approaches to tailor the microstructure, morphology, and interfaces of metal oxide cathodes. Research areas may include (but are not limited to):
- 3D porous/architected cathode designs (e.g., layered oxides, spinel structures).
- Interface engineering (surface coatings, doping, solid-electrolyte interphases).
- In-situ/operando characterization of phase transitions and degradation mechanisms.
- Scalable synthesis techniques (sol-gel, co-precipitation, 3D printing).
We look forward to receiving your contributions.

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. Metals 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 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.
