SBIR Phase II: Lithium Ion Conductor Films for Electrochromic Windows by Spray Coating

这个小企业创新研究（SBIR）二期项目将开发一种新的喷涂方法，用于低成本喷涂溶液衍生的陶瓷、锂离子导电（IC）薄膜，用于建筑电致变色（EC）窗户。对于难以加工的多组分氧化IC层，喷涂是一种潜在的低成本、大批量、在线的方法。第二阶段的研究将解决全尺寸原型在线涂层系统设计的放大问题。目标是演示一个功能齐全，美观统一的25厘米x 30厘米EC器件，该器件采用近似大面积系统条件的方式涂覆IC层。电致变色玻璃预计将对建筑玻璃行业产生影响，因为建筑居住者和业主将能够以电子方式控制窗户玻璃的遮阳。EC玻璃将在需要太阳能控制的地方找到应用，以节省大量能源和提高舒适度。除建筑窗户外，EC玻璃还将适用于交通工具、大面积显示器、娱乐产品和消费电器。除了在电致变色方面的应用之外，这种喷涂技术还可以用于各种其他需要多组分薄膜的产品技术，如可充电锂电池、电光薄膜和特种光学涂层

This Small Business Innovation Research SBIR) Phase II project will develop a novel spray coating methodology for low-cost coating of solution-derived ceramic, lithium-ion conductive (IC) thin films for application in architectural electrochromic (EC) windows. Spray coating is potentially a low-cost, high-volume, in-line route for difficult-to-process, multi-component oxide IC layers. Phase II research will address scale-up issues for design of a full scale prototype in-line coating system. An objective is to demonstrate a functional, aesthetically uniform 25 cm x 30 cm EC device incorporating an IC layer coated in a manner approximating conditions of a large-area system. Electrochromic glazings are expected to impact the architectural glass industry since building occupants owners will be able to control the shading of their window glass electonically. EC glazings will find application where solar control is needed for substantial energy savings and enhanced comfort. In addition to architectural windows, EC glazing will be suited for transportation vehicles, large-area displays, recreational products, and consumer appliances. Beyond application in electrochromics, this spray technology may find use in a variety of other product technologies requiring multi-component thin films such as rechargeable lithium batteries, electro-optical thin films, and specialty optical coatings
