研究目的
Investigating the high performance and excellent stability of all-solid-state electrochromic devices based on a Li1.85AlOz ion conducting layer.
研究成果
The LixAlOz-based ECD achieved a shorter response time, high coloration efficiency, and high transmittance modulation, with super cycling stability of up to 104 time cycles. The Li1.85AlOz ion conducting layer shows potential to replace traditional conducting layers and promote the practical application of ECDs.
研究不足
The study focuses on the performance of LixAlOz films as IC layers in ECDs, but the scalability and cost-effectiveness of the fabrication process for commercial applications are not extensively discussed.
1：Experimental Design and Method Selection:
The LixAlOz films were fabricated by direct current (DC) magnetron sputtering with a Li?Al alloy target. The integrated all-solid-state ECDs were designed with the structure of ITO/NiOx/LixAlOz/WO3/ITO.
2：Sample Selection and Data Sources:
ITO-coated glasses were used as substrates, ultrasonically washed with anhydrous ethanol, acetone, and anhydrous ethanol for 20 min respectively.
3：List of Experimental Equipment and Materials:
DC magnetron sputtering system, Li?Al alloy target, ITO-coated glass, NiOx, WO3, and outer ITO layers.
4：Experimental Procedures and Operational Workflow:
The LixAlOz films were deposited on nickel oxide film by reactive DC magnetron sputtering. The ECDs were fabricated by regulating different productive conditions.
5：Data Analysis Methods:
The optical transmittance properties were tested using a UV?vis?IR spectrophotometer. The electrochemical and electrochromic properties were studied by a CS350 electrochemical workstation.
