In this award, co-funded by the Chemical Structure, Dynamics and Mechanisms A (CSDM-A) Program of the Division of Chemistry and the Energy for Sustainability Program of the Division of Chemical, Bioengineering, Environmental and Transport Systems of the Engineering Directorate, Professor Eric Stuve of the University of Washington and his graduate student researchers are working to develop a better understanding of the chemical reactions that take place at the electrode surfaces in lithium-oxygen batteries, a technologically-promising, new kind of battery. They are investigating the elementary chemical processes that are taking place in model systems using surface science techniques. In doing these experiments, Prof. Stuve and his group are striving to provide researchers with chemical insights that will allow for improved battery performance. Graduate students working on this project will receive training in chemistry and engineering, and Prof. Stuve will continue his efforts at educating the wider public about energy-related research.Prof. Stuve and his research group are conducting a series of experiments on model electrode materials, mimicking the electrode materials in lithium-oxygen batteries. Among the areas being studied are: (1) the study of the growth and morphology of LiOx on the electrode surface; (2) the investigation of the chemical stability of the solvent, including reactions that consume Li and the passivation of the electrode surface; and (3) the exploration of the reaction mechanism and reversibility of oxygen uptake/production. The systems will be studied using a number of sensitive surface science techniques, including Field Emission Microscopy (FEM), Field Ionization Microscopy (FIM), Pulsed Filed Desorption Mass Spectrometry (PFDMS) and Ramped Field Desorption (RFD). Students working on this project will receive training that will prepare them for research positions in academia, national Laboratories or industry.

在这个奖项中，由化学部的化学结构，动力学和机制A（CSDM-A）计划和工程局化学，生物工程，环境和运输系统部的可持续发展计划能源共同资助，华盛顿大学的埃里克·斯图夫教授和他的研究生们正在努力更好地理解化学反应，放置在锂氧电池的电极表面，这是一种技术上很有前途的新型电池。 他们正在使用表面科学技术研究模型系统中发生的基本化学过程。 在进行这些实验时，Stuve教授和他的团队正在努力为研究人员提供化学见解，以提高电池性能。 该项目的研究生将接受化学和工程方面的培训，Stuve教授将继续致力于向更广泛的公众宣传能源相关研究。Stuve教授及其研究小组正在进行一系列模拟锂氧电池电极材料的模型电极材料实验。 正在研究的领域包括：（1）LiOx在电极表面上的生长和形态的研究;（2）溶剂的化学稳定性的研究，包括消耗Li的反应和电极表面的钝化;以及（3）氧气吸收/产生的反应机制和可逆性的探索。 这些系统将使用一些敏感的表面科学技术进行研究，包括场发射显微镜（FEM），场电离显微镜（FEM），脉冲场解吸质谱（PFDMS）和斜坡场解吸（RFD）。 参与该项目的学生将接受培训，为他们在学术界、国家实验室或工业界的研究职位做好准备。
