Development of high capacitance ceramics for electric energy storage

该计划的重点是开发一类新的高介电常数/电容，从而基于钛酸钡陶瓷的高能量密度材料。更具体地说，它专注于设计和制造新一代设备，包括具有巨大商业潜力的电池。如果成功，该计划将对当今的电力储存，分配和使用产生巨大影响。除了高能量存储能力之外，这些新材料和设备的优点将导致重量的大量节省，数量级更快的充电，在一定数量的充电和放电循环之后性能不会劣化，并且消除了与处理诸如金属铅和酸的有害物质相关的问题。通过在钛金属基体上制备高比表面积的薄膜，可以使钛酸钡陶瓷具有高的电容量。这一概念已用于制造能量密度超过200的氧化铝/铝电解电容器（AEC）

The proposed program focuses on the development of a new class of high dielectric constant/capacitance and thus high energy density materials based on barium titanate ceramics. More specifically, it focuses on the design and manufacturing of a new generation of devices including batteries with great commercial potential. If successful the program will have an enormous impact on the present day storage, distribution and use of electric energy. Besides high energy storage capabilities, the advantages of these new materials and devices will result in large savings in weight, orders of magnitude faster charging, no deterioration in performance after a certain number of charging and discharging cycles and elimination of problems associated with disposal of hazardous substances such as metallic lead and acids. High capacitance will be imparted to the barium titanate ceramics by fabricating high surface area films on the titanium metal substrate. This concept has already been used in the manufacture of Alumina/Aluminum Electrolytic Capacitors (AEC) with energy density over 200
