This Small Business Innovation Research (SBIR) Phase I project will demonstrate an improved anode material for lithium-ion batteries using novel hollow carbon nanospheres. Li-ion batteries are currently the preferred form of rechargeable energy storage for many portable devices such as laptop computers and cell phones because of their high energy density, low weight, and high current discharge capabilities. This project seeks to develop new materials for these batteries that will improve the energy storage and lifetime while reducing the production cost. The proposed material is hollow carbon nanospheres which are highly structured graphitic spheres with approximately 40 nm diameters. The production process used to produce the nanospheres is unique from other nanomaterials in that the feedstocks are renewable or recyclable, reducing costs and mitigating the environmental impact caused by waste products. This project will demonstrate that improving the material structure of the anode on the nanoscale will improve the overall performance of the Li-ion battery. This is a demonstration of the promise of nanotechnology to improve products through the rational manipulation of material properties at the microscopic level. This Phase I SBIR project will involve collaboration between industry and academia, providing educational experiences in cutting edge science and engineering for both graduate researchers and undergraduate interns.

这个小企业创新研究（SBIR）第一阶段项目将展示一种使用新型空心碳纳米球的锂离子电池改进阳极材料。锂离子电池由于其高能量密度、低重量和高电流放电能力，目前是用于许多便携式设备（诸如膝上型计算机和蜂窝电话）的可再充电能量存储的优选形式。该项目旨在为这些电池开发新材料，以提高能量存储和寿命，同时降低生产成本。所提出的材料是中空碳纳米球，其是直径约40 nm的高度结构化的石墨球。用于生产纳米球的生产工艺与其他纳米材料不同，因为原料是可再生或可回收的，降低了成本并减轻了废物对环境的影响。该项目将证明，在纳米级上改进阳极的材料结构将提高锂离子电池的整体性能。这是纳米技术通过在微观水平上合理操纵材料特性来改善产品的承诺的证明。第一阶段SBIR项目将涉及工业界和学术界之间的合作，为研究生研究人员和本科生实习生提供尖端科学和工程方面的教育经验。
