Fabricating 2D MoS₂ with Edge Sulfur Vacancy Defects by Heavy Ion Bombardment Shear-Exfoliation for Enhanced Sodium Storage.

ABSTRACT: Vacancy engineering is widely considered an effective approach to modulate the internal electronic structure of electrode materials, enhancing charge-transfer processes/reactions and leading to excellent energy storage properties. Nevertheless, several current techniques of vacancy engineering, such as controlled solvent thermal growth, plasma bombardment, and chemical etching, suffer from high energy inputs and uncontrollable processing kinetics. Herein, a facile and energy-efficient technique of metal ion-assisted shear exfoliation is proposed to synthesize 2D MoS₂ with edge S-vacancies as an anode for sodium ion batteries. Thanks to the implementation of this vacancy technique, few-layer MoS₂ anode with sulfur defects at the edge presents remarkable rate performanc
