General Liquid-Driven Coaxial Flow Focusing Preparation of Novel Microcapsules for Rechargeable Magnesium Batteries.

Abstract in brief

• The study introduces a new method called Liquid-Driven Coaxial Flow Focusing (LDCFF) to create small, controllable microcapsules for magnesium batteries, which are promising due to their high energy, safety, and low cost.
• Using MoS₂-filled microcapsules as a case, the research shows these cathodes can maintain a high capacity of 100mAh/g over 100 cycles, with stable performance at both low (10°C) and high (45°C) temperatures, and good rate capabilities.
• The research also explores how different liquid flow rates affect capsule size and shell thickness, examines electron and ion diffusion inside the capsules through first-principles calculations, and suggests this method can be broadly applied in energy storage material development.]
