项目摘要

The broader impact/commercial potential of this Small Business Technology Transfer (STTR) Phase I project is the development of lightweight, thermally safe batteries with high energy densities that can be charged fast, last a long time, are composed of environmentally benign materials, and can store energy at a low cost. Such batteries would enable the large-scale penetration of long-range electric cars and other electric vehicles, including airplanes and drones in transportation. This process reduces environmental pollution and leads to greater energy efficiency.This STTR Phase I project proposes to use boron nitride based layered ceramic materials as a means of storing electrochemical energy in solid state batteries. This project enhances scientific and technological understanding on the design of advanced functional materials for energy storage at the atomic level. To achieve the targeted high performance energy storage at the macroscopic level, the underlying material structures must be carefully selected on the atomic and molecular levels. Two-dimensional materials, such as graphene or hexagonal boron nitride, may contain functional groups that can be reversibly reduced and oxidized and can be utilized as electroactive species in cathodes of rechargeable batteries. The great advantage of these materials is that they can realize simultaneously high energy and power density for thousands of charging/discharging cycles as demonstrated in graphene oxide batteries with lithium and sodium anodes. Graphene oxide is, however, thermally unstable. The project proposes to substitute graphene oxide with functionalized boron nitride in order to achieve thermal stability while preserving performance. Furthermore, the functionalized boron nitride is also capable to play the role of a solid electrolyte in addition to being an electroactive species. Particular focus will be made on synthesizing -OBF3 functionalized boron nitride. This functional group occurs as a Lewis adduct of surface oxides (such as graphene oxide or boron nitride oxide) with BF3 (an electrolyte component) and is particularly promising as a compact electroactive species and electrolyte.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该小型企业技术转移（STTR）I期项目的更广泛的影响/商业潜力是开发具有高能量密度的轻质，安全性的电池，可以快速充电，持续很长时间，由环境良性材料组成，并且可以以低成本存储能源。这样的电池将使远程电动汽车和其他电动汽车（包括飞机和无人机运输中）大规模渗透。该过程减少了环境污染并提高能源效率。该STTR I期项目建议使用基于氮化硼的分层陶瓷材料作为在固态电池中存储电化学能量的一种手段。该项目增强了对高级功能材料设计的科学和技术理解，以在原子层进行储能。为了在宏观水平上实现靶向的高性能储能，必须在原子和分子水平上仔细选择潜在的材料结构。二维材料（例如石墨烯或六角硼硝化物）可能包含可以可逆地降低和氧化的官能团，并且可以在可充电电池的阴极中用作电活性物种。这些材料的最大优势在于，它们可以同时实现数千个充电/放电周期的高能量和功率密度，如用锂和钠阳极的石墨烯氧化物电池所证明的那样。但是，氧化石墨烯是热不稳定的。该项目建议将氧化石墨烯替代氮化硼，以实现热稳定性，同时保持性能。此外，功能化的硝酸硼还能够发挥固体电解质的作用，除了是一种电活性物种。将特别关注合成-OBF3功能化氮化硼。 This functional group occurs as a Lewis adduct of surface oxides (such as graphene oxide or boron nitride oxide) with BF3 (an electrolyte component) and is particularly promising as a compact electroactive species and electrolyte.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
