Special Issue Information

Dear Colleagues,

Lithium-ion capacitors can generally deliver higher energy density than conventional electric double-layer capacitors (EDLCs) and have much higher power density and a longer life cycle than lithium-ion batteries (LIBs). Due to their great potential to bridge the gap between EDLCs and LIBs, lithium-ion capacitors are becoming extremely important.

Lithium-ion capacitors are a hybrid device with multiple energy storage mechanisms, composed of a LIB-type electrode (electrochemical intercalation or conversion) and an EDLC-type electrode (physical adsorption), operating in a Li-salt-containing organic electrolyte. In recent years, especially in the last 10 years, we have developed our understanding and improved the materials and technologies of lithium-ion capacitors, including cathode and anode materials, electrolytes, and pre-lithiation methods. Lithium-ion capacitors have begun to approach large-scale commercialization from current laboratory research and small-scale production.

It is my pleasure to announce that Molecules (MDPI) is publishing a Special Issue on “Lithium-Ion Capacitors: Trends in Sustainable Energy Storage and Conversion”. As Guest Editors of the journal, I would like to invite you to submit a research paper or a focused review article related to lithium-ion capacitors.

Prof. Dr. Jim P. Zheng
Guest Editor

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. Molecules 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 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.

This review paper aims to provide the background and literature review of a hybrid energy storage system (ESS) called a lithium-ion capacitor (LiC). Since the LiC structure is formed based on the anode of lithium-ion batteries (LiB) and cathode of electric double-layer capacitors (EDLCs), a short overview of LiBs and EDLCs is presented following the motivation of hybrid ESSs. Then, the used materials in LiC technology are elaborated. Later, a discussion regarding the current knowledge and recent development related to electro-thermal and lifetime modeling for the LiCs is given. As the performance and lifetime of LiCs highly depends on the operating temperature, heat transfer modeling and heat generation mechanisms of the LiC technology have been introduced, and the published papers considering the thermal management of LiCs have been listed and discussed. In the last section, the applications of LiCs have been elaborated. Full article

Supercapacitors have gained e wide attention because of high power density, fast charging and discharging, as well as good cycle performance. Recently, expanded graphite (EG) has been widely investigated as an effective electrode material for supercapacitors owing to its excellent physical, chemical, electrical, and mechanical properties. Based on charge storage mechanism, supercapacitors have been divided into symmetric, asymmetric, and hybrid supercapacitors. Here, we review the study progress of EG-based materials to be electrode materials. Furthermore, we discuss the application prospects and challenges of EG-based materials in supercapacitors.
