SBIR Phase II: Nanoparticulate Based Coating Approach for Making Thin Film Batteries

这个小型企业创新研究第二阶段项目将进一步开发独特的材料，证明有潜力使用更低成本的纳米颗粒沉积方法为固态锂离子薄膜电池提供更高性能的纳米结构阴极。一种独特的由沉积在碳纳米管上的锡纳米颗粒组成的纳米复合负极已经开发出来，其容量高于传统锂离子电池的容量。正极工作将致力于开发改进的正极涂层。以经济高效的方式消除便携式电子进步的主要限制的潜力将对工业和社会产生重大影响。重量更轻、功能更强大、可永久充电的固态设备将成为这一努力的结果，从而实现一种新的便携式电力“平台”。此外，固态设计和材料的本质是一次性和环保的。

This Small Business Innovation Research Phase II project will further develop unique materials demonstrated with potential to provide higher performance nanostructured cathodes for a solid state lithium ion thin film battery using a lower cost, nanoparticulate based deposition approach. A unique nanocomposite anode consisting Sn nanoparticles deposited onto CNT has been developed, with capacities higher than typically found in conventional Li ion batteries The cathode work will be directed toward development of improved cathode coatings.The potential to cost-effectively eliminate the primary limitation to portable electronic advances will have a significant impact on industry and society. Lighter weight, more powerful and permanently rechargeable solid state devices that enable a new portable power "platform" will be an outcome of this endeavor. In addition, the nature of the solid-state design and materials is inherently disposable and environmentally friendly.
