Special Issue Information

Dear Colleagues,

Molecular materials can play a fundamental role in the improvement of lithium ion batteries and in the development of new technologies for energy storage (Li-S, Li-air, Na+ and K+ ion batteries, Al, Mg or Ca batteries). This topic has given rise to research dispersed in a wide selection of journals, due to the multidisciplinarity approach required. Consequently, there is a need for a Special Issue to provide a broad survey to address various aspects of the latest research. For readers, this Special Issue provides an opportunity to obtain information concerning the different facets of the application of molecular materials in electrochemical energy storage. For authors, it will be an opportunity to make their results and analyses more visible, and to show that they are active members of the scientific community in their different fileds. Contributions discussing all aspects broadly indicated by the keywords are welcome, as are reviews by experts in the field.

Prof. Riccardo Ruffo
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.

Abstract
We propose a flexible, binder-free and free-standing carbonaceous paper fabricated via electrostatic spray deposition using reduced graphene oxide/carbon nanotube (rGO/CNT) as a promising electrode material for flexible sodium-ion batteries (NIBs).

We propose a flexible, binder-free and free-standing carbonaceous paper fabricated via electrostatic spray deposition using reduced graphene oxide/carbon nanotube (rGO/CNT) as a promising electrode material for flexible sodium-ion batteries (NIBs). The as-prepared rGO/CNT paper exhibits a three-dimensional (3D) layered structure by employing rGO as conductive frameworks to provide sodium-storage active sites and CNT as spacer to increase rGO interlayer distance and benefit the diffusion kinetics of sodium ions. Consequently, the rGO/CNT paper delivers an enhanced sodium ion storage capacity of 166.8 mAh g−1 at 50 mA g−1, retaining an average capacity of 101.4 mAh g−1 when current density sets back 100 mA g−1 after cycling at various current rates. An average capacity of 50 mAh g−1 at 200 mA g−1 was stabilized when cycling up to 300 cycles. The well-maintained electrochemical performance of free-standing rGO/CNT paper is due to the well-established hybrid 3D nanostructures, which demonstrates our carbon based material fabricated by a facile approach can be applied as one of the high-performance and low-cost electrode materials for applications in flexible energy storage devices.
