Novel Architectures for Energy Storage and TransferActive Nanostructures and NanosystemsECCS-0709412PI- Amy L. PrietoColorado State UniversityObjective: The energy needs for society are rapidly outpacing current technology. Nanotechnology will have a profound impact in applications for storing and transporting energy. We propose to integrate our experience in developing new materials with superior physical and electronic properties (Manivannan) and new synthetic methods for the organization of nanoscale materials (Prieto) to fabricate and characterize a novel nanoscale architecture for lithium ion battery technologies. We will fabricate nanowire arrays of novel electrode materials into a new battery architecture. Each anodic nanowire will be coated with a polymer electrolyte, then surrounded by the cathode. Intellectual Merit: The significant advantage of this battery architecture is that the diffusion length for lithium ions between the cathode and anode will be dramatically reduced. While every aspect of lithium ion batteries will benefit from enhanced materials properties, the intellectual merit of this project is in the synergy between the architecture developed by the PI and the optimized cathode materials developed by the co-PI. The ultimate goal of this research is a nanoscale lithium ion battery with faster charge and discharge rates and longer lifetime.Broader Impacts: Dramatic improvement in rechargeable batteries will have broad impacts economically. Furthermore, this is an excellent project for training students because the components are modular - one student is in charge of the cathode, anode, or electrolyte, but then must collaborate to effectively combine them into a functional device. The PI's will continue to include their cutting-edge research in several undergraduate and graduate courses, as well as actively recruit talented students from underrepresented groups.

用于储能和转移纳米结构和纳米系统的新型体系结构-0709412Pi-Amy L. Prietocolorado State UniversityBigntive：社会的能源需求迅速超过了当前技术。 纳米技术将对存储和运输能源的应用产生深远的影响。 我们建议将我们的经验与开发新材料具有优越的物理和电子特性（Manivannan）以及用于组织纳米级材料（PRIETO）的新合成方法，以制造和表征用于锂离子电池技术的新型纳米级建筑。 我们将在新的电池架构中制造纳米线阵列。 每个阳极纳米线将用聚合物电解质涂层，然后被阴极包围。 智力优点：该电池架构的显着优势是，锂离子在阴极和阳极之间的扩散长度将大大减少。 尽管锂离子电池的每个方面都将受益于增强的材料特性，但该项目的智力优点在于PI开发的架构与Co-Pi开发的优化阴极材料之间的协同作用。 这项研究的最终目标是纳米级锂离子电池，充电速度和放电率更快，寿命更长。Boader的影响：可充电电池的显着改善将在经济上产生广泛的影响。 此外，这是培训学生的绝佳项目，因为组件是模块化的 - 一个学生负责阴极，阳极或电解质，但随后必须协作以有效地将它们组合到功能设备中。 PI将继续包括他们在几个本科和研究生课程中的尖端研究，并积极招募来自代表性不足的团体的才华横溢的学生。
