Abstract
Polyoxometalates (POMs) are considered highly suitable for electrochemical energy storage due to their advantageous structural and electrochemical features. As inorganic molecular clusters, POMs exhibit high thermal and chemical stability, tunable redox potentials, and a wide range of compositions, making them attractive for use in electrochemical storage devices. This work systematically explores the unique advantages of POMs-based materials, including their redox reactions and charge storage mechanisms. The introduction of conductive polymers into electrochemical devices shows remarkable enhanced performances, and the assembled solid-state capacitor 1-CC@PANI-SC achieved a maximum specific capacitance of 86.8 mAh g -1 , an energy density of 14.16 Wh kg -1 with power density of 802.57 W kg -1 . This study provides a promising insight for the design and synthesis of purely inorganic polyoxometalates and applications in energy storage devices.
