Special Issue Information
In recent years, there has been a rapid increase in the number of publications involving PIBs, especially research on PIB anodes, and the resulting PIBs have obvious improved electrochemical performance. Therefore, PIBs are expected to store intermittent electricity for smart grid regulation and to be used as a power source for continuous electricity supply.
As we all know, the interfacial behaviors, namely K-ion diffusion from the electrolyte to the electrode surface and K-ion migration between different active particles, usually play an essential role in thermodynamic and diffusion/reaction kinetics. An improved interface property is expected to greatly boost ion diffusion and electron transport ability as well as maintain structure stability, thus contributing to promoting rate, cycling performance, and Coulombic efficiency.
The performances or behaviors of the solid/liquid interface are usually related to the stability of solid electrolyte interface phase (SEI) layer, but large volume variations, particle pulverization, and maldistribution of electrode materials may cause the instability of SEI film.
Solid/solid interface properties are often affected by the high transport resistance and low electrochemical reaction. Consequently, exploring interfacial transmission mechanisms and controlling interfacial transport to improve diffusion/reaction kinetics are highly desirable and are responsible for enhanced electrochemical performance in terms of cycling stability and rate capability.

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.
