Cover Picture: Compatibility of Molybdenum Disulfide and Magnesium Fluorinated Alkoxyaluminate Electrolytes in Rechargeable Mg Batteries (Batteries & Supercaps 9/2024)

Abstract

The Front Cover shows how the sluggish (de)intercalation of Mg²⁺ in MoS₂ cathode materials was overcome by using Mg²⁺/Li⁺ dual-salt electrolytes. The simultaneous insertion of Mg²⁺ and Li⁺ ions notably boosted the electrochemical performance of MoS₂ in rechargeable magnesium batteries allowing the cell to achieve a remarkable initial specific capacity of 100 mAh g⁻¹, almost three times higher than the specific capacity of MoS₂ in Mg single-salt electrolytes.
