SBIR Phase I: Lithium Reservoir Nanocarbons for Lithium Ion Batteries

这个小企业创新研究（SBIR）第一阶段项目将利用最近发表的研究成果，该研究表明，新型阳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。这项工作将使用空心碳纳米纤维来生产锂离子电极，其性能接近或超过理论值（即LiC6的电性能）。这些纤维的独特形态，即空心芯、叠杯、结构和开放的石墨平面，有望促进可逆锂离子嵌入。在过去的十年中，锂离子电池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、廉价的锂离子电池在从消费电子产品到太空飞行器的各种市场中享有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化为锂离子电池生产商和用户的现有客户群的事实，为这项前沿研究带来了巨大的希望。

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.
