About the workshop

Background

We are continuing the tradition which was established in Ulm, Germany, in 2016 where the 1st International Zinc-Air Battery Workshop was hosted. During the last years, significant effort has been made to develop post Li-ion technologies. Due to this a renewed interest in the "old" Zn-air battery has come into focus because of the many advantages such as high specific energy, low cost, good safety record, etc. However, mainly caused by the drawback of low cycle life, electrically rechargeable Zn-air batteries have still not found their market yet.

In order to further support the development of the zinc-air battery systems by setting/defining the international state-of-the-art, discussing promising R&D pathways for the technical improvement and by initiating international co-operation we will organize an international workshop.

Decentralized application of batteries in the low voltage end of distribution grids is expected to become an early business case following the increase in solar power installations seen all over Europe. Metal-air batteries are considered preferable with regards to energy density. Several metals have been considered for the development of metal-air batteries; e.g. Mg, Zn, Al, Fe, Ca and Li. Among these metals, zinc is the most active metal that can be electrodeposited from an aqueous electrolyte, is abundant in nature and can be handled safely in oxygen and humid atmosphere. However, achieving a rechargeable zinc-air battery is challenging due to degradation of the electrodes during cycling, which results in a rapid reduction in (storage) capacity. In order to support the further development of zinc-air systems, we hereby invite the Zn-air battery research community to the 2nd International Zn-air battery workshop in Trondheim, Norway. This will promote open discussions regarding promising R&D pathways for the technical improvement of these batteries.
