Summary: | Hybrid dual-ion batteries have attracted much attention due to their low cost, high working voltage, and environmental friendliness. Since most of the reported hybrid dual-ion batteries use organic electrolytes, their safety issues remain to be studied, and their electrochemical performance is still unsatisfactory. In this work, we proposed an aqueous hybrid dual-ion battery based on Zn/MoSe
2
and realized the fast charging of the aqueous hybrid dual-ion battery for the first time. This novel hybrid dual-ion battery exhibits a high specific capacity of 134 mAh g
−1
and excellent cycle stability (cycle life of 1000 times above) at a rate of 2C. In addition, the battery can store 84% of the battery capacity in 5 min after charging, with the specific capacity of 93 mAh g
−1
, which shows its potential in high-rate fast charge–discharge energy storage applications. |
