This SBIR Phase I research project would demonstrate proof of principle for the production of ultra capacitors with energy densities competitive with lithium ion batteries, but that can be charged in seconds to minutes as opposed to hours or days. These ultra capacitors are based on the development of new, super-high permittivity (30-100,000 epsilon) nanostructured titanate particles that allow for high charge storage along with high dielectric breakdown strength that are arranged in percolative networks in a very low cost polymeric film. More specifically, the project goal will be to demonstrate multilayer capacitor prototypes having dielectric breakdown strength above 5000 V/mil and effective permittivity above 20,000 (goal is 30,000) at room temperature, and demonstrate the feasibility of fabricating these formulations into capacitor devices using an innovative low cost metallized film production technology. The successful development of high energy ultra capacitors having energy storage densities above 150 J/cc has the potential to revolutionize energy storage and power conversion technologies for backup power supplies, as well as plug-in and hybrid vehicles by greatly reducing the size and cost of energy storage systems. Competing products are flywheel storage, advanced battery chemistries, and electrolytic capacitors, which are all substantially more expensive and have lower performance. The primary current market for film-foil super-capacitors is high peak power electrical applications and includes pulse power supplies (lasers and flash lamps), defibrillators, and high rep rate applications.

该SBIR I期研究项目将证明具有与锂离子电池具有能量密度竞争的超电容器的原理证明，但可以在几秒钟到几分钟的时间内与小时或数小时相比，这可以充电。这些超电容器基于开发新的，超高的介电常数（30-100,000个EPSILON）纳米结构的钛酸颗粒，可提供高电荷存储以及在非常低成本的聚合物膜中渗透性网络中排列的高介电分解强度。更具体地说，项目目标将是在室温下展示具有介电分解强度高于5000 V/mil的多层电容器原型，并且有效的介电常数（目标为30,000），并证明使用创新的低成本金属化金属胶片生产技术，证明了将这些配方制造为电容器设备的可行性。具有能源储能密度高于150 j/cc的高能超电容器的成功开发有可能通过大大降低储能存储系统的尺寸和成本来彻底改变备用电源的能源存储和功率转换技术，以及插件和混合动力汽车。竞争产品是飞轮存储，高级电池化学和电解电容器，这些电容器的昂贵且性能较低。胶片超级电容器的主要当前市场是高峰值电气电气应用，包括脉冲电源（激光灯和闪光灯），除颤器和高rep速率应用。
