SBIR Phase I: Monodispersed Carbon Nanotubes for High Power Energy Storage Devices

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。近年来，高比表面积碳被用作电化学超级电容器的电极材料。然而，迄今为止，电化学超级电容器的能量密度远远低于理论上达到的标准。造成这种情况的一个主要原因是由于碳表面的电解质溶液的限制，电极材料的全部容量的利用存在问题。降低或消除碳粉之间的颗粒间接触电阻也是至关重要的，这是实现高性能充放电特性的电极。该项目旨在通过一项创新来跨越这些技术障碍，该创新专注于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，安森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、构建原型和现场测试技术。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，在军事应用中使用便携式和小型化的电子设备和执行器。其他应用包括电动汽车的混合动力系统，计算机和电子仪器的存储备份系统，激光和相机闪光灯设备的脉冲电源，以及便携式消费产品的电源。

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.
