Molecular Engineering to Construct MoS2 with Expanded Interlayer Spacing and Enriched 1T Phase for “Rocking-Chair” Aqueous Calcium-Ion Pouch Cells

anode is assembled. The pouch cell exhibits a life of 150 cycles with over 90.8% capacity retention at 0 and 25 °C. This work demonstrates that molecular engineering is an effective strategy to improve the calcium storage performance of TMDs and promotes the advancement of ACIBs.
