This Small Business Innovation Research (SBIR) Phase I project will leverage recently-published research which indicates that new types of anode nanocarbons can produce high reversible lithium (Li) storage capacity and stable cycle capability. The work will use hollow carbon nanofibers to produce Li-ion electrode performance which is close to or surpasses theoretical values (i.e., the electrical performance of LiC6). The unique morphology of these fibers, i.e., a hollow core, stacked cup, structure and open, graphitic planes, is expected to facilitate reversible Li-ion intercalation. Over the past decade, lithium ion has developed into a mainstream battery technology with considerable commercial impact. Safe, rechargeable, inexpensive Li-ion batteries are enjoying a growing customer base in diverse markets - from consumer electronics to space vehicles. As mature as this industry is, there are still good prospects for achieving major performance improvements through the use of advanced materials. The unique morphology of the carbon nanofibers and the fact that these materials can readily be transitioned into an existing client base of Li-ion battery producers and users holds great promise for this cutting-edge research.

这个小型企业创新研究(SBIR)第一阶段项目将利用最近发表的研究，该研究表明新型负极纳米碳可以产生高可逆锂(Li)存储容量和稳定的循环能力。这项工作将使用中空碳纳米纤维来产生接近或超过理论值(即LiC6的电性能)的锂离子电极性能。这些纤维的独特形态，即中空的芯、堆叠的杯状结构和开放的石墨化平面，有望促进可逆的锂离子插层。在过去的十年里，锂离子已经发展成为一种主流的电池技术，具有相当大的商业影响。安全、可充电、廉价的锂离子电池正在不同市场--从消费电子产品到太空飞行器--享受着越来越多的客户基础。尽管这个行业已经成熟，但通过使用先进材料实现重大性能改进的前景仍然很好。碳纳米纤维的独特形态，以及这些材料可以很容易地转变为锂离子电池生产商和用户的现有客户基础的事实，为这一尖端研究带来了巨大的希望。
