The ulm helmholtz institute and the karlsruhe institute of technology in Germany are jointly developing magnesium-based energy storage technologies. Magnesium battery is a project under the eu's "vision 2020" research program (e-magic), for which the eu has invested more than 6.5 million euros, bringing together the expertise of 10 European research institutions. If the project is successful in the future, it is expected to replace the existing lithium ion battery.
Magnesium batteries have more advantages than conventional lithium-ion batteries. According to the institute of helmholtz ulm, deputy director of the project within the maxi, Millie fichte, professor, director of introduction, magnesium is one of the important candidate materials after lithium strategy, magnesium as anode material, allowed to have a high energy density, magnesium battery than lithium ion battery energy storage is more efficient, cheaper, more secure, "magnesium battery widespread availability, to promote the development of electric cars and distributed energy storage technology has a decisive role".
The ulm helmholtz institute, in collaboration with the karlsruhe institute of technology and the German aerospace centre, has developed the e-magic project for the research and design of electrochemical concepts for magnesium batteries. The ulm helmholtz scientists hope to help partners understand material barriers and challenges and find new ways to address current barriers.
Dr. Zhirong zhao, who coordinated the solid-state chemistry research, said magnesium batteries face a particular challenge in terms of longevity, which is currently a major concern. But magnesium battery does have many attractive features, for example, magnesium anode won't form dendritic crystal, electrode on the electrochemistry of sediment in the lithium ion battery can be formed acicular structure, cause interference and even short circuit, and magnesium is not similar problems, that is why we can use metal magnesium, in the form of direct use of magnesium can increase the storage capacity of battery, improve the performance of the battery.
In addition to its safety and higher energy density, earth has about 3,000 times more magnesium than lithium, and it is easier to recycle. As a result, magnesium batteries are cheaper than lithium-ion ones and help reduce the need for lithium as a raw material in battery manufacturing.
As the eu makes progress in developing magnesium batteries, it will also help reduce reliance on Asian battery makers and build a competitive battery manufacturing industry in Europe.
