Special Issue Information
Dear Colleagues,
Two-dimensional (2D) materials, including graphene, Mxenes, and transition metal dichalcogenides, have attracted significant attention for energy storage owing to their unique physicochemical properties. Their ultrathin structure, coupled with electron confinement, imparts exceptional electronic characteristics that are advantageous for electrochemical performance. Their high specific surface area promotes efficient utilization of active sites, while enhanced electrode/electrolyte contact shortens ion transport pathways. In addition, tunable interlayer spacing enables effective ion intercalation, and their structural flexibility supports the development of flexible device architectures. Collectively, these features make 2D materials promising candidates for next-generation supercapacitors, rechargeable batteries, and hybrid systems, offering improved capacity, rate capability, and long-term cycling stability compared to conventional bulk materials.
However, several critical challenges, including layer restacking, limited structural stability, and sluggish reaction kinetics, still hinder the practical application of 2D materials. To address these issues, various strategies have been explored, such as defect and interface engineering, heteroatom doping, and the design of hybrid architectures with other low-dimensional materials (e.g., nanoparticles and nanotubes). These approaches improve electrochemical performance by creating additional ion transport channels within the interlayer spaces, increasing the accessible active surface area, and enhancing electrical conductivity.
This Special Issue aims to highlight recent advances in the synthesis, structural design, characterization, and performance evaluation of 2D materials for energy storage. Particular emphasis will be placed on developing innovative and sustainable synthesis strategies to overcome challenges related to structural and electrochemical stability. In addition, attention will be given to cost-effective, scalable, and environmentally friendly methods, along with efforts to deepen mechanistic understanding of charge storage using advanced characterization techniques in supercapacitors and rechargeable batteries. Original research articles and review papers providing significant scientific insights and innovations in this field are highly encouraged.

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 250 words) can be sent to the Editorial Office for assessment.
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.
