摘要
Rechargeable aqueous zinc ion batteries (AZIBs) with the advantages in low cost, high safety, and environmental friendliness have broad application prospects in the field of energy storage. However, the slow intercalation kinetics of multivalent Zn2+ migration make it hard to find a suitable cathode. Herein, HNO3 etched MoS2 with edge‐enriched feature is proved to be a promising cathode for high‐performance AZIBs. The highly exposed edges with superior electrochemical activity can not only offer more reactive sites for zinc storage but also accelerate the reaction kinetics. As a result, the edge‐enriched MoS2 cathode exhibited higher specific capacity of 187 mAh g−1 at 0.1 A g−1 and outstanding cycling performance (89% capacity retention after 700 cycles at 1 A g−1).
