The Helmholtz Institute (HIU) of Karlsruhe Institute of Technology (KITs) has developed a new type of electrolyte that can be used in magnesium-sulfur batteries and has a higher density of storage than lithium. In addition, magnesium is rich in nature, non-toxic, and not easy to degrade in the air. This research is published in Advanced Energy Materials magazine. Many electronic devices use lithium ion and metal hydride batteries for energy storage. Scientists are also researching new technologies that can replace these existing battery systems to improve the safety, cost-effectiveness, sustainability and performance of future devices. Therefore, all the battery components need to be re-developed, need to understand the electrochemical process. At present, magnesium batteries are expected to replace lithium batteries, the storage density is higher than lithium. In addition, magnesium in nature rich in energy storage, non-toxic, and lithium different from the air is not easy to degrade. To design a large capacity and high power density of magnesium batteries, electrolytes need to be easy to produce, high stability, and can be used in different high concentrations of solvents. The Helmholtz Institute, led by Maximilian Fichtner and Zhirong Zhao-Karger, has developed a new electrolyte that can be used in magnesium-sulfur batteries and is very promising. Has an unprecedented electrochemical stability window, and energy efficiency is very high. In addition, the electrolyte can be used in a variety of solvents, suitable for high concentrations. Maximilian Fichtner said: "Another advantage is that the electrolyte production process is very simple.Only need to use two kinds of commercially available chemicals, magnesium amide and aluminum chloride, add it to the solvent and stir, and finally form a simple mixture, Can be used directly as a battery electrolyte.
