9861395 This Small Business Innovation Research Phase I project will use a novel synthesis route to develop monodispersed carbon nanotubes for high power energy storage applications. High surface area carbons have been used as the electrode materials in recently developed electrochemical supercapacitors. However, the energy densities achieved to date for electrochemical supercapacitors have fallen far short of the theoretically attained mark. One major reason for this has been problems with utilization of the full capacity of the electrode materials, due to restriction of electrolyte solution accessible to much of the carbon surface. It is also essential to reduce or eliminate particle to particle contact resistances among the carbon powders, which constitute the electrode for high performance charge discharge characteristics. This program seeks to leap frog these technology barriers with an innovation that focuses on monodispersed carbon nanotubes as electrode materials for electrochemical supercapacitors. During Phase I, Amsen will demonstrate the proof-of-concept of such a material. Phase II will build on Phase I success, optimize, build prototypes and field test the technology in partnership with potential customers. Phase III will commercialize the technology and anticipated spin off. High power density, reliable electrochemical supercapacitors would find a large market in military applications where portable and miniaturized electronics and actuators are being used. Other applications include hybrid power systems for electric vehicles, memory backup systems for computers and electronic instruments, pulsed power source for lasers and camera flash equipment, and power source for portable consumer products.

9861395 这个小企业创新研究第一阶段项目将使用一种新的合成路线来开发用于高功率储能应用的单分散碳纳米管。 高比表面积碳材料已被用作最近开发的电化学超级电容器的电极材料。 然而，迄今为止电化学超级电容器所达到的能量密度远远低于理论上所达到的水平。 其一个主要原因是，由于限制了电解质溶液可接近大部分碳表面，因此存在利用电极材料的全部容量的问题。 还必须减少或消除碳粉末之间的颗粒对颗粒的接触电阻，碳粉末构成用于高性能充电放电特性的电极。 该计划旨在跨越这些技术障碍，重点是将单分散碳纳米管作为电化学超级电容器的电极材料。 在第一阶段，Amsen将展示这种材料的概念验证。 第二阶段将在第一阶段成功的基础上，与潜在客户合作，优化、构建原型并现场测试该技术。 第三阶段将使该技术商业化，并预计将产生副产品。 高功率密度，可靠的电化学超级电容器将在军事应用中找到一个巨大的市场，其中使用便携式和小型化的电子设备和致动器。 其他应用包括用于电动汽车的混合动力系统、用于计算机和电子仪器的存储器备份系统、用于激光和相机闪光设备的脉冲电源以及用于便携式消费产品的电源。
