SBIR Phase I: Low Cost Manufacturing of Novel Vanadium Nitride based Asymmetric Supercapacitors

这个小型企业创新研究（SBIR）第一期项目旨在开发基于氮化钒（VN）的低成本制造工艺。该方法是将纳米结构VN的合成与其在集流基板上的沉积相结合。合成和沉积相结合的工艺降低了制造成本和资本设备费用。在电流集电极上直接沉积薄层活性材料可使阻抗最小化并使峰值功率能力最大化。该计划是研究激光烧结氧化钒薄层和激光辅助氮化，评估在不对称超级电容器中得到的VN薄电极的技术性能，并确定对性能增强和优化至关重要的设计因素。该项目的更广泛/商业影响将是提供一种低成本的沉积方法，这将彻底改变汽车和智能电网应用的不对称、高能量密度超级电容器的制造。这项技术有望将超级电容器的成本降低30%，并将不对称电池的能量密度提高25%。

This Small Business Innovation Research (SBIR) Phase I project aims to develop low-cost manufacturing processes of Vanadium Nitride (VN) based asymmetric supercapacitors. The approach is to combine the synthesis of nanostructured VN with its deposition on a current collector substrate. The combined synthesis and deposition process reduces manufacturing costs and capital equipment expenses. The direct deposition of thin layers of active material on the current collector minimizes the impedance and maximizes peak power capabilities. The plan is to investigate laser sintering of thin layers of vanadium oxides and laser assisted nitridation, assess technical performance of the resulting thin VN electrodes in an asymmetric supercapacitor, and identify design factors critical to performance enhancement and optimization. The broader/commercial impact of this project will be the potential to provide a low-cost deposition method that will revolutionize the manufacturing of asymmetric, high energy density supercapacitors for automotive and smart grid applications. This technology is expected to reduce the cost of supercapacitors by 30% and improve the asymmetric cell energy density by 25%.
