January 04, 2019 By Christoph Hammerschmidt
The E-Magic research project aims to develop batteries that are more powerful, cheaper and safer than the widespread lithium-ion battery. This project focuses on novel magnesium-based batteries. The research project, funded by the European Union (EU) with over 6.5 million euros, brings together the activities of various European scientific institutions, including the Karlsruhe Institute of Technology (KIT), the University of Ulm (Germany) and the German Aerospace Center DLR.
According to the scientists, magnesium batteries should have decisive advantages over conventional lithium-ion batteries: Magnesium as an anode material enables a higher energy density and would also be much safer in the event of a fire. "Magnesium is a promising material and one of the most important candidates for our post-lithium strategy," says Professor Maximilian Fichtner, Deputy Director of the Helmholtz Institute Ulm (HIU) , a research institute founded by KIT in cooperation with the University of Ulm and the associated partners DLR and ZSW to research and develop electrochemical battery concepts. "A broad availability of magnesium batteries could decisively advance the electrification of mobility and the expansion of decentralised home storage systems. In order to accelerate the development of this new type of battery, the HIU is now cooperating with other scientific institutions in the field of battery and materials research in the European Magnesium Interactive Battery Community (E-Magic) research project.
In the project, the partners combine all necessary steps for the development of magnesium batteries, from basic research to cell production processes. The main aim of the scientists is to contribute to understanding the obstacles and challenges at the materials level and to create new solutions for current obstacles. "The special challenge with magnesium batteries is a long service life," explains Dr. Zhirong Zhao-Karger, who coordinates the activities of the new research project in the Solid State Chemistry Research Group at HIU. However, there are a number of positive properties of the new battery material that the researchers want to use: for example, no dendrites form on the magnesium anodes. In lithium-ion batteries, such electrochemical deposits on the electrodes can form needle-like structures and cause disturbances or even dangerous short circuits. There are no comparable processes in magnesium. It is therefore possible to use magnesium in metallic form and thus directly utilize the high storage capacity of the metal.
In addition to greater safety and energy density, the introduction of magnesium technology in battery production could also help to reduce dependence on lithium as a raw material: as an element, magnesium is around 3,000 times more abundant on earth than lithium and, in contrast, is much easier to recycle. Accordingly, magnesium batteries would also be cheaper than lithium-ion batteries. If Europe makes rapid progress in development, magnesium batteries could also help to reduce the dominance of Asian producers of battery cells and establish competitive battery production in Europe.

Energy storage is a key technology to facilitate a widespread integraWith the growing use of intermittent energy sources in power grids, there is a growing mismatch between when energy is produced and when it is consumed. This has led to the need of energy storage or demand-response systems in order to use the energy in a balanced and efficient way. Given this context, the Micro Energy Storage (MES) systems are expected to seek radically new approaches to supply energy where it is needed. Buildings are becoming a local use micro energy-hubs consuming, producing, storing, supplying energy and having the potential to take up an important role in the power-supply system stability which generate energy with renewables, provide storage for electric and thermal energy and deliver demand response. For Micro Energy Storage in Buildings (MESB) using stochastic renewables energy, the most suitable technology is the lithium-ion batteries (LIB). However, current LIB technologies are facing severe challenges in safety, energy density and price. While most of today's R&D is concentrated on LIB systems, shifting towards non-lithium rechargeable batteries may open up effective ways to overcome such challenges. The rechargeable magnesium battery (RMB) constitutes a paradigmatic example of such promising, alternative non-lithium energy storage systems, following pioneering efforts and breakthroughs from world-wide researchers. The potential to use metallic magnesium anodes in rechargeable batteries brings important advantages in terms of energy density, cost and safety. E-MAGIC gathers the key scientific and technical researchers in Europe to develop the required new frontier knowledge and foundational approaches on RMB, bringing an effective work on R&D by a rational design of high voltage/high capacity cathode materials and novel electrolytes to overcome the rate-limiting reaction and transport processes, in order to deliver a safe RMB with more 400 Wh kg-1 and less than 100 €/Kwh.
