Repairable electrochromic energy storage devices: A durable material with balanced performance based on titanium dioxide/tungsten trioxide nanorod array composite structure

Electrochromic-capacitive bifunctional materials have been widely developed in recent years due to their broad application prospects. However, the failure to achieve all-round excellent performance simultaneously, as well as the limited stability restricted their large-scale commercialization. Here, we prepared a TiO2/WO3 nanorod composite material, which showed balanced electrochromic and capacitive properties without any significant...
