Review article on aluminum-ion battery belongs to the “Most Viewed”

The article “The Aluminum-Ion Battery: A Sustainable and Seminal Concept?” belongs to the “Most Viewed” articles in the journal “Frontiers in Chemistry – Inorganic Chemistry”.

In Mai 2019 the article “The Aluminum-Ion Battery: A Sustainable and Seminal Concept?” was published in the Journal “Frontiers in Chemistry – Inorganic Chemistry” as part of the Research Topic “Realizing Multivalent Batteries: Recent Developments and Challenges”. Tilmann Leisegang, as an expert in the field of solid electrolytes especially for high-valent battery materials, had been invited by the guest editors, Pieremanuele Canepa from the National University of Singapore, Sai Gautam Gopalakrishnan from the Princeton University, Alexandre Ponrouch from the Instituto de Ciencia de Materiales de Barcelona, and Jordi Cabana from the University of Illinois at Chicago, back in 2018. Since November 2019 this article with more than 10,000 views belongs to the “Most Viewed” articles in this section. Moreover, this article has already more views than 93% of all Frontiers articles ever published.

Batteries and crystallographyBatteries and thus electrochemistry are becoming increasingly topical as a result of global energy change, the push of electromobility, and the recently awarded Nobel Prize in Chemistry. The article collection goes beyond lithium battery material concepts, with the article by Tilmann Leisegang and his coauthors describing the constraints for a sustainable and seminal battery chemistry. It furthermore presents an assessment of the chemical elements in terms of negative electrodes, comprehensively motivate utilizing aluminum, categorize the aluminum battery field, critically review the existing positive electrodes and solid electrolytes, present a promising path for the accelerated development of novel materials, and address problems of scientific communication in this field.

In 2013 the Institute of Experimental Physics (IEP) started to work on battery materials. Under the leadership of Tilmann Leisegang as project manager of two BMBF projects (CryPhysConcept and R2RBattery), methods for the identification of novel ionic conductors were developed in cooperation with the Samara Center for Theoretical Materials Science, headed by Vladislav Blatov and with Stefan Adams from the National University of Singapore. Aluminum as a material for negative electrodes was systematically determined by a comprehensive evaluation of all non-artificial chemical elements of the periodic table. This as well as the current knowledge of the IEP is summarized in the recently published book “Electrochemical storage materials – From Crystallography to Manufacturing Technology“ published by DeGruyter in 2019.

In May 2019, the European Commission issued the list “100 Radical Innovation Breakthroughs for the future”, which mentions the aluminum-based battery chemistry as the only battery technology. “This shows the importance of our research” says Tilmann Leisegang, “but a diversification in battery chemistries is all the more important because the material supply challenges we will face are even greater.”
