A novel hybrid, composed of Co3O4quantum dots supported on Ti3C2Tx(MXene) nanosheets, exhibits a strong synergetic effect, and shows superior lithium storage (capacity = 766.5 mA h g−1at 2 A g−1after 400 cycles) and oxygen evolution (overpotential = 340 mV at 10 mA cm−2) activities.

Lithium-sulfur (Li-S) batteries face a few vital issues, including poor conductivity, severe volume expansion/contraction, and especially the detrimental shuttle effect during the long-term electrochemical process. Herein, we designed a hierarchical...
