SBIR Phase I: High Energy Density Film Capacitators

这个SBIR第一阶段的研究项目将证明生产超级电容器的原理，其能量密度与锂离子电池竞争，但可以在几秒到几分钟内充电，而不是几小时或几天。这些超级电容器是基于新型的超高介电常数（30-100,000 epsilon）纳米结构钛酸盐颗粒的开发，该颗粒允许高电荷存储以及高介电击穿强度，并在极低成本的聚合物薄膜中以渗透网络排列。更具体地说，该项目的目标将是展示在室温下介电击穿强度高于5000 V/mil，有效介电常数高于20,000（目标是30,000）的多层电容器原型，并展示使用创新的低成本金属化薄膜生产技术将这些配方制造成电容器器件的可行性。储能密度超过150j /cc的高能超级电容器的成功开发，有可能通过大大减少储能系统的尺寸和成本，彻底改变备用电源以及插电式和混合动力汽车的储能和功率转换技术。与之竞争的产品有飞轮存储、先进的电池化学成分和电解电容器，这些产品都要贵得多，性能也差得多。目前薄膜箔超级电容器的主要市场是高峰值功率电气应用，包括脉冲电源（激光和闪光灯）、除颤器和高重复率应用。

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.
