SBIR Phase I: The Development of a Process to Synthesize Open-Ended Buckytubes and Intercalate them with Lithium for the Use of Lithium Batteries

* 9561217 Wang 这个小企业创新研究第一阶段项目将开发和展示一种合成开放式巴基管的工艺，并将其嵌入锂，用作锂电池的新电极材料。 迄今为止报道的所有实验都表明，在惰性气体电弧中产生的巴基管在端部被封盖。 该公司已经证明，尖锐的，开放式的纳米管与空的内部可以在氢弧放电合成。 开放式巴基管的可用性使得可以填充管并制造具有前所未有的新颖性质的全新一维材料，例如导电或半导电“量子线”、超短波长光波导、具有最高拉伸强度的纳米纤维等。 第一阶段计划，通过系统的研究，将完善开口巴基管的合成工艺，并将具有强电子亲和力的开口巴基管插入锂，以生产碳锂比高于目前石墨的电极材料。这对于高性能、低成本和非常安全的可充电锂供应和存储系统非常重要。 ***

*** 9561217 Wang This Small Business Innovation Research Phase I project will develop and demonstrate a process to synthesis open-ended buckytubes and intercalate them with lithium to be used as new electrode materials for lithium batteries. All experiments reported to date have shown that buckytubes produced in inert gas arcs are capped at the ends. The firm has demonstrated that sharp, open-ended nanotubes with empty interiors can be synthesized in a hydrogen arc discharge. The availability of open-ended buckytubes makes it possible to fill the tubes and fabricate completely new one-dimensional materials with unprecedented, novel properties such as conducting or semiconducting "quantum wires", ultra-short wavelength optical waveguides, nanofibers with the highest tensile strength etc. In this Phase I program, the process for synthesis of open-ended buckytubes will be perfected through a systematic investigation, and the open-ended buckytubes with strong electron affinity will be intercalated with lithium to produce electrode materials with a higher ratio of carbon to lithium than can be obtained with current graphite. This could be extremely important to high performance, low cost, and very safe rechargeable lithium supplies and storage systems. ***
