Recent Advances Towards Commercialization of Solid-State Batteries

Dear Colleagues,

Solid-state batteries (SSBs) have emerged as a key technology to overcome the intrinsic limitations of conventional lithium-ion batteries, offering enhanced safety and higher energy density. However, despite remarkable advances in materials design, interfacial engineering, and manufacturing technologies, several critical challenges remain before SSBs can achieve large-scale commercialization. This Special Issue aims to provide a comprehensive overview to highlight the latest progress in materials development, cell and module design, and scalable fabrication processes that bridge the gap between laboratory-scale innovation and industrial implementation.

We invite original research articles, reviews, and perspectives that address scientific, engineering, and techno-economic challenges in the development of high-performance SSBs suitable for real-world applications. Contributions that provide insights into scale-up technologies, commercialization pathways, and cost optimization are particularly encouraged.

Topics of interest include, but are not limited to, the following:

• Advanced solid electrolytes and electrode materials enabling practical SSBs;
• Interfacial engineering and stability enhancement for long-term cycling;
• Scalable processing and manufacturing technologies for SSB production;
• Cell architecture design and integration strategies for high energy density;
• Degradation mechanisms and lifetime prediction in SSB systems;
• Cost analysis and techno-economic perspectives on SSB commercialization;
• Pouch cell-level prototypes and pilot-scale demonstrations;
• Low pressure and/or room temperature operation of SSBs.

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 collection 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.
