Special Issue Information

Dear Colleagues,

This Special Issue is jointly organized and initiated by the 10th Academic Conference on Key Materials for Supercapacitors and Related Chemical Power Sources and the MDPI journal Batteries. The scope of solicitation includes but is not limited to double-layer capacitors/pseudocapacitors, metal/non-metal ion capacitors, power electronic capacitors, organic batteries such as lithium/sodium/potassium, aqueous batteries, solid-state energy storage and wearable devices, hydrogen energy and fuel cells, electrochemical energy storage theory and calculation, electrochemical energy storage equipment and technology, electrochemical energy storage system and integration, etc. The purpose of this Special Issue is to strengthen relevant academic exchanges, cooperation, and the publication of the latest scientific research results in the industry, further build a platform for interaction and cooperation between universities, research institutes, companies, investment and financing institutions, and relevant government departments, share innovative scientific research results, discuss domestic and foreign dynamics and frontiers, clarify industrial development trends, carry out industry–university–research cooperation, promote the research of supercapacitors and related chemical power source key materials and the development of new energy industries, and serve the national "dual-carbon" strategy.

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. Batteries 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 2700 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.

Sodium–ion battery capacitors (SIBatCs) synergistically combine battery–type and capacitor–type components in an inter–parallel configuration, simultaneously delivering high energy and power densities. We pioneer the development of quasi–commercial pouch SIBatCs using Na3V2(PO4)3/activated carbon (NVP/AC) hybrid cathodes and hard carbon anodes. The hybrid design utilizes NVP as an intrinsic sodium source, eliminating complex anode presodiation—an obstacle to industrialization. The AC component fulfills multiple roles—contributing capacitive capacity, enhancing conductivity, and acting as an electrolyte reservoir, which decreases electrode resistivity as well as polarization. In full cells, an optimal NVP/AC mass ratio range of 10:1–2:1 is identified, enabling balanced low resistance, high energy density, exceptional power density, and long cycle life. SIBatCs incorporating R10/1 (mNVP:mAC = 10:1) and R4/1 (mNVP:mAC = 4:1) achieve energy densities of 148.9 Wh kg−1 (81.0 W kg−1) and 120.6 Wh kg−1 (79.3 W kg−1), respectively. Even at ultrahigh power densities of 30.53 and 29.81 kW kg−1, they retain corresponding energy densities of 50.4 and 39.6 Wh kg−1. They exhibit excellent capacity retentions of 32.8% and 41.6% after 5000 cycles—significantly outperforming pure NVP–based cells (18.0%). The hybrid architecture ensures robust performance across a wide temperature range (−30–60 °C). This work presents a scalable solution for high–performance sodium–ion EES hybrid systems. Full article
