The ideal solution to large-scale energy storage will allow fast storage and release of energy in a device such as a reusable electrical storage medium. The proposed work is focused on realizing high energy density storage in a capacitor made with a ceramic of high dielectric constant. The PIs propose a novel approach, which is the combination of a ferroelectric nanopowder and a low melting and alkali-free glass to improve on current electrochemical capacitors. The main advantage of a ceramic capacitor over conventional capacitors is the fast discharge rate. A device resulting from this work could lead to a new method for storing intermittently available electrical energy from sources such as solar cells and wind turbines. A goal of this project is to discover novel materials capable of high energy density storage in capacitors. Such materials will both withstand high electric fields (~1 MV/cm) and possess an extremely high dielectric constant (~100,000). To realize this in prototype test devices, and in a commercially viable way, is a complicated problem of ceramic science and glass engineering. In this project, improvements in electrical energy density will be achieved by storing energy capacitively using a composite of a ferroelectric nanopowder (e.g., [Ba(Ti0:8Zr0:2)O3]0.80-[(Ba0:7Ca0:3)TiO3]0.20 and/or Pb[(Fe1/2Nb1/2)0.6-(Fe2/3W1/3)0.4)O3]) and low melting, alkali-free glass (e.g., B2O3-SiO2-PbO-BaO-TiO2 or B2O3-SiO2-ZnO-BaO-TiO2). The dielectric constant of the glassy phase can be increased by controlled crystallization after the sealing. The broader impact of the proposed research is to develop a novel approach to energy storage that will potentially find application in many areas including environmental protection, consumer electronics, electric vehicles, and healthcare. Being able to efficiently store large amounts of intermittent renewable energy would be a key step in meeting the nation?s and the world?s demand for energy. In addition, the innovative approach coupled with the coordination of multiple disciplines to study a new concept for renewable energy storage will impact the basic curriculum, i.e., concepts in renewable energy storage will be taught from an engineering perspective in design, fabrication, and data analysis. The PIs will exchange students between the Rensselaer Polytechnic Institute and the University of Puerto Rico to promote integration between the two different student populations as well as the RPI NSF Center for Nanotechnology and the UPR Institute for Functional Nanomaterials.The FY 2010 EFRI-RESTOR Topic that supports this project was sponsored by the US National Science Foundation (NSF) directorates for Engineering (ENG), Mathematical and Physical Sciences (MPS) and Social, Behavioral and Economic Sciences (SBE), and Computer & Information Science and Engineering in collaboration with the US Department of Energy (DOE).

大规模能量存储的理想解决方案将允许在诸如可重复使用的电存储介质的设备中快速存储和释放能量。 所提出的工作的重点是实现高能量密度存储在电容器制成的高介电常数的陶瓷。PI提出了一种新的方法，即铁电纳米粉末和低熔点无碱玻璃的组合，以改善当前的电化学电容器。陶瓷电容器相对于传统电容器的主要优点是放电速率快。 这项工作产生的一种装置可能会导致一种新的方法，用于存储来自太阳能电池和风力涡轮机等来源的间歇性可用电能。 该项目的目标是发现能够在电容器中存储高能量密度的新型材料。 这种材料既能承受高电场（~1 MV/cm），又具有极高的介电常数（~ 100，000）。在原型测试设备中实现这一点，并以商业上可行的方式，是陶瓷科学和玻璃工程的一个复杂问题。在该项目中，电能密度的提高将通过使用铁电纳米粉末（例如，[Ba（Ti 0：8 Zr 0：2）O 3]0.80-[（Ba 0：7 Ca 0：3）TiO 3]0.20和/或Pb[（Fe 1/2Nb 1/2）0.6-（Fe 2/3 W 1/3）0.4）O 3]）和低熔点无碱玻璃（例如，B2O3-SiO2-PbO-BaO-TiO2或B2O3-SiO2-ZnO-BaO-TiO2）。 玻璃相的介电常数可以通过密封后的受控结晶来增加。 拟议研究的更广泛影响是开发一种新的储能方法，该方法可能在许多领域得到应用，包括环境保护，消费电子产品，电动汽车和医疗保健。能够有效地储存大量间歇性可再生能源将是满足国家需求的关键一步？s和世界？对能源的需求。此外，创新的方法加上多学科的协调，研究可再生能源存储的新概念将影响基础课程，即，可再生能源储存的概念将从设计，制造和数据分析的工程角度教授。 PI将在伦斯勒理工学院和波多黎各大学之间交换学生，以促进两个不同学生群体之间的融合，以及RPI NSF纳米技术中心和UPR功能纳米材料研究所。2010财年支持该项目的EFRI-RESTOR主题由美国国家科学基金会（NSF）工程董事会（ENG）赞助，数学和物理科学（MPS）和社会，行为和经济科学（SBE），以及计算机&信息科学与工程与美国能源部（DOE）合作。
