Special Issue Information

Dear Colleagues,

Since Sony introduced lithium ion batteries (LIBs) in 1991, a rapid development has taken place. Due to improvements and expansions, LIBs are, nowadays, state-of-the-art for modern portable consumer electronics. Furthermore, they are considered the most promising battery technology for electronic vehicles (EVs), hybrid electric vehicles (PHEVs) and hybrid electric vehicles (HEVs), as well as for stationary storage applications for renewable energies. However, the main disadvantage of lithium ion batteries is the degradation process over time, the so-called aging, which is closely connected to the limited cycle and calendar life. Due to the complexity of LIB cells, numerous aging mechanisms have been suggested. Therefore, there is a variety of reports about methodologies and analyses in literature regarding the aging behavior of LIBs. Especially, the investigation of the electrolyte aging is intensively based on the application of separation techniques like gas chromatography (GC), ion chromatography (IC), liquid chromatography (LC) and capillary electrophoresis (CE). However, most of the reaction mechanisms are still not completely understood or verified. Thus, the development of analytical methodologies, mainly based on chromatographic or hyphenated techniques, is mandatory for further investigations.

We would like to invite colleagues to contribute with original research articles and reviews to the present Special Issue on the latest trends in separation and hyphenated techniques for the analysis of LIBs.

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. Separations 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 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.

Lithium ion batteries (LIBs) are widely used in numerous application areas, including portable consumer electronics, medicine, grid storage, electric vehicles and hybrid electric vehicles. One major challenge during operation and storage is the degradation of the cell constituents, which is called aging. This phenomenon drastically reduces both storage lifetime and cycle lifetime. Due to numerous aging effects, originating from both the individual LIB cell constituents as well as their interactions, a wide variety of instruments and methods are necessary for aging investigations. In particular, chromatographic methods are frequently applied for the analysis of the typically used liquid non-aqueous battery electrolytes based on organic solvents or ionic liquids. Moreover, chromatographic methods have also been recently used to investigate the composition of electrode materials. In this review, we will give an overview of the current state of chromatographic methods in the context of LIB cell research. Full article
