Lithium-Sulfur Batteries: Latest Advances and Prospects

Dear Colleagues, 

Li-ion batteries are becoming an increasingly ubiquitous tool in our race for green energy transformation. However, they are reaching their theoretical limit where they cannot satisfy the increasing demand for higher energy-dense solutions. Thus, it is highly imperative to develop next-generation batteries to cope with such high energy demand and complement Li-ion batteries in the energy storage market. Lithium-sulfur (Li–S) batteries are among the most commercially promising next-generation battery technologies with cells offering a substantial increase in gravimetric energy density and lower cost. However, outstanding obstacles for their commercialization, including poor rate capability and long cycle life, are still prevalent due to polysulfide dissolution, poor electronic conductivity of the cathode, and lithium anode instability. The understanding of cell chemistry and electrochemical mechanisms are key to enabling Li-S technology.

To address these challenges and promote the commercialization of Li-S batteries, this Special Issue will focus on contributions covering the following areas:

1. Engineered and functionalized cathodes;
2. Anodes;
3. Electrolytes and redox mediators;
4. Polysulfide shuttling mitigation;
5. Anode-electrolyte interfaces;
6. Solid-State Li-S;
7. Computational and machine learning studied;
8. Commercialisation prospective.

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 250 words) can be sent to the Editorial Office for assessment.

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.
