Researchers from the Suzhou Institute of Nano-Tech and Innovation at the Chinese Academy of Sciences, led by Hongzhen Lin, have teamed up with Dr. Jian Wang from the Karlsruhe Institute of Technology in Germany to tackle the challenges of sluggish ion desolvation and polysulfide conversion in magnesium-sulfur batteries. Their innovative approach involves the development of a catalytic MIL101-GF material featuring a hierarchical pore structure. This material effectively facilitates magnesium ion diffusion, desolvation, and redox reactions by modulating the Mg²⁺ solvation structure, thereby significantly boosting the kinetics of sulfur reactions.
