چکیده
Tungsten trioxide (WO3) has been widely regarded as a prospective bifunctional material due to its electrochromic and pseudocapacitive properties, while still facing the dilemma of inadequate cycle stability trapping-induced degradation. Here, inspired by trees-strengthening approach, unique titanium dioxide (TiO2) nanorod arrays strengthened WO3 nano-trees (TWNTs) heterojunction was rationally designed constructed. In sharp contrast transmittance modulation (ΔT) attenuation primary during cycling, TWNTs film showed not only excellent performance but also fascinating (77.35% retention initial ΔT after 10,000 cycles). Besides, degradation could be easily rejuvenated potentiostatic de-trapping process. An energy storage device (EESD) further assembled based on deliver (up 79.5% at 633 nm), fast switching speed (tc/tb =1.9 s/14.8 s), extremely high coloration efficiency value (443.4 cm2·C−1), long-term (over charge/discharge This innovative study provided in-depth insights into electrochromism nature significant step in realization stable electrochromic-energy application, paving way for multifunctional smart windows well next-generation optoelectronic devices.

Paper, invented more than 2,000 years ago and widely used today in our everyday lives, is explored in this study as a platform for energy-storage devices by integration with 1D nanomaterials. Here, we show that commercially available paper can be made highly conductive with a sheet resistance as low as 1 ohm per square (Omega/sq) by using simple solution processes to achieve conformal coating o...
متن کاملPhase Restructuring in Transition Metal Dichalcogenides for Highly Stable Energy Storage.
Achieving homogeneous phase transition and uniform charge distribution is essential for good cycle stability and high capacity when phase conversion materials are used as electrodes. Herein, we show that chemical lithiation of bulk 2H-MoS2 distorts its crystalline domains in three primary directions to produce mosaic-like 1T' nanocrystalline domains, which improve phase and charge uniformity du...
