Special Issue Information

Dear Colleagues,

The materials used in rechargeable ion batteries, including non-aqueous systems (such as lithium ions, sodium ions, potassium ions, magnesium ions, or calcium ions) and aqueous zinc-ion batteries, have been developed to the deepest level, reaching a point beyond structural modifications at nano-/micrometer scales. This means that facet engineering has become increasingly important in recent years. The performances of the rechargeable ion batteries mentioned above are generally closely related to the lattice or facet structure of the candidate materials, such as the lattice spacing and lattice exposed ratios, which are of high importance in materials science but have rarely been investigated, particularly their correlations with ion storage behaviors and the corresponding mechanisms that could originally influence ion storage performance.

Thus, this Special Issue, “Methodologies and Mechanisms in Facet Engineering for Next-Generation Ion Batteries”, will cover methodologies and related mechanisms for facet engineering in material synthesis (mostly concerning inorganic materials), which could include hydrothermal and solvothermal methods, chemical vapor deposition (CVD), or electro-deposition for facet engineering to improve the performance of rechargeable ion batteries. Performance metrics could include capacity delivery, cyclic performance, and related electrochemical ion storage mechanisms. Articles, reviews, and prospective papers are all welcome.

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.

With the rapid growth of renewable energy, the need for efficient and stable energy storage systems has become increasingly urgent. Aqueous zinc-ion batteries (AZIBs) can offer high safety, abundant zinc supply, and promising electrochemical properties. However, their performance is limited by poor electronic conductivity, slow Zn2+ diffusion, and structural degradation of conventional cathode materials. To address these issues, an in situ polyaniline (PANI) intercalation strategy for vanadium oxide cathodes is introduced in this paper. The conductive PANI chains play three key roles: (1) expand and stabilize interlayer spacing, (2) enhance electronic conductivity, and (3) provide mechanical support to prevent structural collapse and zinc-dendrite formation. A flower-like PANI-V2O5 hybrid is synthesized via synchronous oxidative polymerization, forming a hierarchical architecture without inert intercalants. The resulting electrode achieves a high specific capacity of 450 mAh·g−1 at 0.1 A·g−1 and retains 96.7% of its capacity after 300 cycles at 1 A·g−1, with excellent rate performance. These findings demonstrate that PANI intercalation enhances ion transport, electronic conductivity, and structural integrity, offering a promising design approach for next-generation AZIBs cathodes.
