In this project, funded by the Chemical Structure, Dynamics & Mechanisms B Program of the Chemistry Division, Professors Chao Luo and Andre Clayborne of the Department of Chemistry and Biochemistry at George Mason University are investigating the electrochemistry of carboxylate compounds in rechargeable sodium batteries and rechargeable potassium batteries. They are seeking a fundamental understanding of the correlation between chemical structures and electrochemical behaviors. Rechargeable sodium batteries and rechargeable potassium batteries are attractive alternatives to the well-known lithium ion battery, which are widely used in electric cars, electronic, and energy storage. Research activities will involve graduate, undergraduate, high school, and middle school students. Outreach activities include the development of sustainable battery workshops for high school and middle school students, and the training of high school students with basic hands-on skills for battery research to enhance their interests in science, technology, engineering, and mathematics. Current inorganic anodes limit the development of rechargeable sodium batteries and rechargeable potassium batteries, because of low capacity, poor cycle life, and sluggish reaction kinetics. Carboxylate compounds, with their advantages of lightweight and low cost, stand out as promising anode materials for rechargeable sodium batteries and rechargeable potassium batteries. However, they can suffer from low Coulombic efficiency and slow reaction kinetics. Professors Chao Luo and Andre Clayborne plan to overcome these limitations by studying functional groups, heteroatoms, conjugation structure, structural isomerism, and interfacial chemistry in conjunction with computation chemistry and data analytics. Innovative structure design and facile fabrication approaches will be developed to synthesize carboxylate-based organic anodes. The combination of extensive electrochemical and material characterizations, in situ/ex situ electrode measurements, and computational chemistry could lead to the fundamental understanding of the battery chemistry of new carboxylate anodes.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.

在该项目中，由化学系化学结构、动力学机制B计划资助，乔治梅森大学化学与生物化学系的罗超和安德烈·克莱伯恩教授正在研究羧酸盐化合物在可充电钠电池和可充电钾电池中的电化学。 他们正在寻求对化学结构和电化学行为之间相关性的基本理解。 可再充电钠电池和可再充电钾电池是众所周知的锂离子电池的有吸引力的替代品，其广泛用于电动汽车、电子和能量存储。 研究活动将涉及研究生、本科生、高中生和中学生。 外联活动包括为高中生和中学生举办可持续电池研讨会，并培训高中生掌握电池研究的基本实践技能，以提高他们对科学、技术、工程和数学的兴趣。目前的无机阳极限制了可再充电钠电池和可再充电钾电池的发展，因为容量低、循环寿命差和反应动力学缓慢。 羧酸盐化合物以其重量轻、成本低等优点成为可充钠电池和可充钾电池的理想负极材料。 然而，它们可能遭受低库仑效率和缓慢的反应动力学。 Chao Luo和Andre Clayborne教授计划通过研究官能团，杂原子，共轭结构，结构异构和界面化学，结合计算化学和数据分析来克服这些限制。 本研究将发展新颖的结构设计与简易的制造方法来合成羧酸盐有机阳极。 广泛的电化学和材料表征、原位/非原位电极测量和计算化学的结合可以从根本上了解新型羧酸盐阳极的电池化学。该奖项反映了NSF的法定使命，并且通过使用基金会的知识产权进行评估，被认为值得支持优点和更广泛的影响审查标准。
