This Small Business Innovation Research (SBIR) Phase II project will develop Li-ion battery anodes that exploit the unique morphology of low cost carbon nanofibers (CNF). Primary efforts will focus on reduction of irreversible capacity, through a variety of nanofiber surface modification techniques, characterization of the upper limits of anode discharge rate, and development of a new type of compound anode material that combines CNF with elements that form high energy alloys of lithium. The latter effort has the potential to combine the high rate capability of CNF with the higher operation voltage of alloys in a manner that synergistically increases the reversible capacity of both components of the compound anode. Safe, rechargeable, inexpensive Li-ion batteries are enjoying a growing customer base in diverse markets from consumer electronics to space vehicles. The unique morphology of 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.

这个小企业创新研究（SBIR）第二阶段项目将开发利用低成本碳纳米纤维（CNF）独特形态的锂离子电池阳极。主要工作将集中在通过各种表面改性技术降低不可逆容量，表征阳极放电速率的上限，以及开发一种新型复合阳极材料，该材料将CNF与形成锂的高能合金的元素相结合。后一种努力具有以协同增加复合阳极的两种组分的可逆容量的方式将CNF的高倍率能力与合金的较高操作电压结合的联合收割机的潜力。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拥有越来越多的客户群。碳纳米纤维的独特形态以及这些材料可以很容易地过渡到锂离子电池生产商和用户的现有客户群中的事实，为这项尖端研究带来了巨大的希望。
