Hui Wang, Xiaolan Song, Miao Lv, Shengming Jin, more

Small > 18 > 3 > n/a - n/a

Antimony sulﬁde is attracting enormous attention due to its remarkable theoretical capacity as anode for sodium‐ion batteries (SIBs). However, it still suffers from poor structural stability and sluggish reaction kinetics. Constructing covalent chemical linkage to anchor antimony sulﬁde on two‐dimension conductive materials is an effective strategy to conquer the challenges. Herein, Ti₃C₂‐Sb₂S₃ composites...
