SBIR Phase I: Electrode Material Development for SuperCapacitor

这个小型企业创新研究(SBIR)第一阶段项目旨在开发低成本的基于活性碳纳米纤维的超级电容器电极材料，具有存储大能量和功率密度的能力。以聚丙烯腈、沥青、酚醛和木质素为原料的聚合物前驱体纳米纤维将使用静电纺丝工艺生产。这些纳米纤维将被转化为活性碳纳米纤维，其表面积超过用于超级电容器的传统电极材料的3到5倍。纳米纤维结构将通过改变孔结构、电极厚度、表面积和其他产品特性来定制，以实现所需的功率和能量性能。超级电容器是电动汽车、消费和工业电子及电动工具、电源管理等应用的候选对象。低成本碳电极材料的成功开发将使超级电容器材料制造商能够以相对较低的成本生产这些器件，并将在成本和经济方面对整个市场产生广泛的影响。

This Small Business Innovation Research (SBIR) Phase I project intends to develop low cost activated carbon nanofiber based ultracapacitor electrode material with ability to store large energy and power density. Polymer precursor nanofibers from polyacrylonitrile, pitch, phenolic, and lignin will be produced using an electrospinning process. These nanofibers will be converted to activated carbon nanofiber with surface area in excess of 3 to 5 times more than the conventional electrode material used in supercapacitors. The nanofiber architecture will be tailored to achieve the desired power and energy performance by varying pore structure, electrode thickness, surface area, and other product properties. Supercapcitors are candidates for many applications including electric vehicles, consumer and industrial electronics and power tools, power management, etc. Successful development of low cost carbon electrode material will allow supercapacitor material manufacturer to produce these devices at relatively low cost and will have broad effect on overall market in terms of cost and economics.
