Objective: The objective of this program is to develop scalable nanomanufacturing technologies for the production of high-energy density electrochemical capacitors, consisting of nanostructured electrodes with controllable charged defect density and redox polymers. This aspect of nanoscale engineering is transformative in that the constituent electrodes have a unique combination of both double-layer and redox capacitance, with very large area leading to higher energy density and low electrical resistance for enhanced power density.Intellectual merit: The intellectual merit is defined through the scope of the work, which aims to integrate from the bottom up, all the necessary processes for a carbon based high energy storage density device. This includes nanostructure synthesis through a roll-to-roll process, plasma processing for electrical charge introduction, in-line metrology to provide real-time monitoring of the structural properties, for the ultimate purpose of deploying fully functional capacitors. Fundamental insights into electrochemical mechanisms and material interactions will be obtained and applied to the development of proof-of-concept devices and prototype systems.Broader impacts: The broader impacts are the development of high-energy density carbon nanomaterials compatible with large-scale device fabrication technologies, and extending the reach of nanotechnology to budding scientists and the wider community. The potential applications for high-energy electrochemical capacitors range from small-scale portable electronics (requiring high power density and large cycle life) to large-format energy management. In addition to promoting graduate and undergraduate education and training on nanotechnology and process integration, outreach activities will promote novel energy technologies.

目的：该计划的目标是开发可扩展的纳米制造技术，用于生产高能量密度的电化学电容器，由具有可控带电缺陷密度和氧化还原聚合物的纳米结构电极组成。纳米级工程的这一方面是变革性的，因为组成电极具有双层和氧化还原电容的独特组合，具有非常大的面积，导致更高的能量密度和低电阻，以提高功率密度。智力价值是通过工作范围来定义的，其目的是自下而上地整合，用于碳基高能量存储密度装置的所有必要工艺。这包括通过卷对卷工艺进行纳米结构合成、用于引入电荷的等离子体处理、提供结构特性实时监测的在线计量，最终目的是部署功能齐全的电容器。对电化学机制和材料相互作用的基本见解将被获得并应用于概念验证设备和原型系统的开发。更广泛的影响：更广泛的影响是与大规模设备制造技术兼容的高能量密度碳纳米材料的开发，并将纳米技术的范围扩展到崭露头角的科学家和更广泛的社区。高能电化学电容器的潜在应用范围从小型便携式电子产品（需要高功率密度和长循环寿命）到大型能源管理。除了促进研究生和本科生关于纳米技术和工艺一体化的教育和培训外，外联活动还将促进新的能源技术。
