E-MAGIC is coordinated by the FundaciГіn Cidetec, Spain.Д®-MAGIC is to pool all steps required for the development of magnesium batteries, from fundamental research to cell production processes. This project funded by the EU under the вЂњHorizon 2020вЂќ program will pool the expertise of ten scientific institutions, with the HIU being granted a high six-digit amount. вЂњWide availability of magnesium batteries might push electrification of mobility and increasing use of decentralized home storage systems.вЂќ To accelerate the development of the novel battery type, HIU cooperates with other scientific institutions in the area of battery and materials research within the research project European Magnesium Interactive Battery Community (E-MAGIC). вЂњMagnesium is a very promising material and one of the most important candidates for our post-lithium strategy,вЂќ says Professor Maximilian Fichtner, Deputy Director of the Helmholtz Institute Ulm (HIU), a research institute established by KIT in cooperation with Ulm University and the associated partners DLR and ZSW for the investigation and development of electrochemical battery concepts. E-MAGIC is funded by the European Union (EU) with more than EUR 6.5 million and is to pool the relevant activities of various European science institutions.Д¬ompared to conventional lithium-ion batteries, a magnesium battery has many advantages: When using magnesium as an anode material, energy density is increased and safety is enhanced. This research was conducted with the support from the National Research Foundation of Korea grant funded by the Korean government (2020 M2D8A2093081, 2018R1C1B6004908).A better performance, lower costs, and enhanced safety compared to lithium-ion batteries: These are the hopes of scientists of Karlsruhe Institute of Technology (KIT) and their cooperation partners in relation to novel magnesium batteries to be developed under the E-MAGIC research project. Reference: вЂњA Dry Room-Free High-Energy Density Lithium-ion Batteries Enabled by Impurity Scavenging Separator MembraneвЂќ by Hye Bin Son, Myoungsoo Shin, Woo-Jin Song, Dong-Yeob Han, Sungho Choi, Hyungyeon Chad, Seoha Nam, Jaephil Cho, Sinho Choi, Seungmin Yoo and Soojin Park, 19 January 2021, Energy Storage Materials. вЂњWith this first successful case of fabricating batteries in ambient air, it is expected to play a big role in reducing battery cost.вЂќ вЂњThis newly developed multi-functional separator shows great stability and excellent electrochemical performance at high energy density,вЂќ remarked Professor Soojin Park who has long been studying battery separators through various approaches. Moreover, through this research, the team confirmed that this multi-functional separator produced in the ambient air this time exhibits superior lifespan than the conventional separators, confirming that it provides stable performance beyond the role of a simple separator. The silane compound on the surface of the synthesized functional ceramic traps moisture and maintains the ceramic structure well, but the general ceramic material was corroded by the acidified electrolyte.

Conventional separator had 50% shrinkage) and further showed improved electrochemical performance at the high temperature of 55? (79% of the initial capacity maintained after 100 charging cycles).ДЄdditionally, the researchers confirmed the effectiveness of the functional material in the electrolyte in the impurity-filled environment. This multi-functional separator demonstrated excellent heat resistance (shrinkage within 10% after 30 minutes of storage at 140?. To this, the joint research team introduced functional materials that can trap impurities on the surface of the separator to increase thermal stability and improve battery performance.

Therefore, there is a need for a material capable of trapping moisture and impurities in the battery without adverse electrochemical reactions to the additives. In fact, when batteries are activated at a high temperature (50? or higher), even a small bit of moisture causes faster performance deterioration. But these can cause unwanted side reactions during the battery operation. To solve this issue, studies have been conducted to suppress impurities - such as moisture or hydrofluoric acid - by injecting additives into the electrolytes. Battery production in ambient air using a multi-functional separator.
