- Abstract
Aqueous zinc‐ion batteries have been considered as potential energy storage devices owing to their high safety and low cost. Traditional zinc‐ion batteries often implement a typical Zn2+ insertion/extraction mechanism. Compared with traditional Zn2+ insertion/extraction mechanism, supercapacitor‐liked dual‐ion mechanism often endow the batteries with higher operating voltage, better rate capability, and longer cycle life. Herein, aqueous Zn/polyaniline batteries are developed, which can combine the Zn2+ insertion/extraction and dual‐ion mechanisms. The Zn/polyaniline batteries deliver excellent electrochemical performance, especially a long cycle life up to 3000 cycles with high‐capacity retention of 92%. This hybrid mechanism provides a promising battery chemistry. Furthermore, Zn/polyaniline batteries can be assembled into quasi‐solid‐state soft‐packaged and cable‐type configurations and display stable electrochemical performance even under different bending states, showing potential applications for flexible electronics. Zn2+ insertion/extraction and dual‐ion mechanisms are combined in aqueous Zn/polyaniline (Zn/PANI) batteries. Such Zn/PANI batteries exhibit excellent electrochemical performance, especially a long cycle life over 3000 cycles with high‐capacity retention of 92%. Furthermore, quasi‐solid‐state soft‐packaged and cable‐type Zn/PANI batteries are assembled. They display stable performance even under different bending states.
