Special Issue Information

Dear Colleagues,

Electrochemical energy storage devices have attracted recent attention due to the rapid development of electric vehicles, consumer electronics, and energy storage power stations, among other advancements. In addition to large-scale commercial lithium-ion batteries, other batteries, such as sodium-ion batteries, have entered the commercial stage. To achieve improved performance, lower cost, and higher security in batteries, high-performance energy storage materials, including anode and cathode materials, must be developed. This Special Issue, with the aim of stimulating scientific research and industry development, will provide an overview of the latest advances of electrode materials in various electrochemical battery systems, including lithium-ion batteries, sodium-ion batteries, aqueous zinc-ion batteries, and so on. We look forward to papers presenting novel electrode materials or methods, research on the modification of existing materials, and studies on electrochemical energy storage electrode materials.

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.

In this paper, a Si@EG composite was prepared by liquid phase mixing and the elevated temperature solid phase method, while polyaniline was synthesized by the in situ chemical polymerization of aniline monomer to coat the surface of nano-silicon and exfoliated graphite composites (Si@EG). Pyrolytic polyaniline (p-PANI) coating prevents the agglomeration of silicon nanoparticles, forming a good conductive network that effectively alleviates the volume expansion effect of silicon electrodes. SEM, TEM, XRD, Raman, TGA and BET were used to observe the morphology and analyze the structure of the samples. The electrochemical properties of the materials were tested by the constant current charge discharge and cyclic voltammetry (CV) methods. The results show that Si@EG@p-PANI not only inhibits the agglomeration between silicon nanoparticles and forms a good conductive network but also uses the outermost layer of p-PANI carbon coating to effectively alleviate the volume expansion of silicon nanoparticles during cycling. Si@EG@p-PANI had a high initial specific capacity of 1491 mAh g−1 and still maintains 752 mAh g−1 after 100 cycles at 100 mA g−1, which shows that it possesses excellent electrochemical stability and reversibility.
