Performance Improvement of Magnesium Sulfur Batteries with Modified Non‐Nucleophilic Electrolytes
Zhirong Zhao-Karger,Xiangyu Zhao,Xiangyu Zhao,Di Wang,Thomas Diemant,R. Jürgen Behm,Maximilian Fichtner +6 more
TL;DR: In this paper, a new preparation method for non-nucleophilic electrolyte solutions using a two-step reaction in one-pot is presented, which provides a feasible way to optimize the physiochemical properties of the electrolyte for the application in magnesium sulfur batteries.
Journal ArticleDOI
A new class of non-corrosive, highly efficient electrolytes for rechargeable magnesium batteries
TL;DR: In this paper, the concept of ion conducting salts opens a promising avenue towards the realization of high-energy magnesium batteries, due to the non-corrosive, chemically stable nature and the robust, economic synthesis.
Journal ArticleDOI
Performance study of magnesium–sulfur battery using a graphene based sulfur composite cathode electrode and a non-nucleophilic Mg electrolyte
B. P. Vinayan,Zhirong Zhao-Karger,Thomas Diemant,Venkata Sai Kiran Chakravadhanula,Nele I. Schwarzburger,Musa Ali Cambaz,R. Jürgen Behm,Christian Kübel,Maximilian Fichtner +8 more
TL;DR: The use of a graphene-sulfur composite cathode electrode, with the properties of a high surface area, a porous morphology, a very good electronic conductivity and the presence of oxygen functional groups, along with a non-nucleophilic Mg electrolyte gives an improved battery performance.
Journal ArticleDOI
Toward Highly Reversible Magnesium–Sulfur Batteries with Efficient and Practical Mg[B(hfip)4]2 Electrolyte
Zhirong Zhao-Karger,Runyu Liu,Wenxu Dai,Zhenyou Li,Thomas Diemant,B. P. Vinayan,Christian Bonatto Minella,Xingwen Yu,Arumugam Manthiram,R. Jürgen Behm,Mario Ruben,Mario Ruben,Maximilian Fichtner +12 more
TL;DR: In this article, the authors demonstrate that magnesium tetrakis(hexafluoroisopropyloxy) borate Mg[B(hfip)4]2 satisfies a multitude of requirements for an efficient and practical electrolyte, including high anodic stability, high ionic conductivity, and excellent long-term Mg cycling stability with a low polarization.
Journal ArticleDOI
Altered thermodynamic and kinetic properties of MgH2 infiltrated in microporous scaffold
Zhirong Zhao-Karger,Jianjiang Hu,Arne Roth,Di Wang,Christian Kübel,Wiebke Lohstroh,Maximilian Fichtner +6 more
TL;DR: MgH(2) nanoparticles with a size of <3 nm were formed by direct hydrogenation of Bu( 2)Mg inside the pores of a carbon scaffold by reducing activation energy and reaction enthalpy for the nanoconfined system.
