Sea-Cucumber-like Microstructure Polyoxometalate/TiO₂ Nanocomposite Electrode for High-Performance Electrochromic Energy Storage Devices.

ABSTRACT: The key challenge in the practical application of electrochromic energy storage devices (EESDs) is the fabrication of high-performance electrode materials. Herein, we deposited K₇[La(H₂O)_x(α₂-P₂W₁₇O₆₁)] (P₂W₁₇La) onto TiO₂ nanowires (NW) to construct an NW-P₂W₁₇La nanocomposite using a layer-by-layer self-assembly method. In contrast to the pure P₂W₁₇La films, the nanocomposite exhibits enhanced electrochromic and electrochemical performance owing to the 3D sea-cucumber-like microstructure. An EESD using the NW-P₂W₁₇La film as the cathode exhibited outstanding electrochromic and energy storage properties, with high o
