Overview

Experimental study demonstrates enhanced charge kinetics and cycling stability in polyoxometalate-polyaniline hybrid nanospheres, highlighting a viable route for durable zinc-ion batteries.

Key Points

To develop durable hybrid cathode materials that overcome slow ion diffusion and rapid structural degradation in aqueous zinc-ion batteries.
Synthesized mesoporous polyoxometalate-intercalated polyaniline nanospheres using sacrificial colloidal silica templates and electrostatic co-assembly.
Etched silica templates to yield an interconnected mesoporous network combining conductive polyaniline chains with redox-active vanadium-manganese polyoxometalate clusters.
Evaluated rate capability and cycling retention alongside in-situ spectroscopic characterization of charge-storage mechanisms.
The hybrid cathode achieved specific capacities of 264 mAh g–1 at 0.5 A g–1 and 147 mAh g–1 at 3.0 A g–1.
The material exhibited 90.6% capacity retention after 1000 cycles at a high current density of 5.0 A g–1.
In-situ analyses confirmed energy storage occurs via reversible polyaniline benzenoid–quinoid transitions coupled with reversible vanadium- and manganese-oxygen coordination changes.
