There is an increasing demand for high-performance and reliable energy storage technologies, especially lithium-ion batteries (LIBs), for many cutting-edge applications such as long-range electric vehicles and large-scale smart grids. Reliability and cyclability are among the most critical bottlenecks in the current LIBs technologies for these markets. In general, the compositional and structural instabilities of electrode materials are the most encountered problems responsible for the reliability issues. The state-of-the-art approach to improve the electrode stability is to protect the electrode surfaces using inhomogeneous coating layers. However, the internal resistance generated at the electrode/coating-layer interface has negative effects on performance. This project will investigate the controllable synthesis and electrochemical stability of FGM in LIBs for next-generation energy storage technologies. The project also includes related course development, undergraduate research experience and outreach plans to local high schools. This project aims to understand the interfacial stabilization mechanism of lithium battery (LIB) electrodes through a controllable surface reconstruction and to establish experimental approaches for constructing functional graded materials (FGM) for durable LIBs. The project will use in-situ synchrotron X-ray characterization techniques to identify battery chemistry, coordination geometry, and phase transition behaviors in FGM coated electrodes. The project will comprehensively access the processing-structure-property relationship of FGM for LIBs by integrating advanced characterizations with electrochemical analyses. The research goals will be accomplished through the following objectives: (1) understanding the formation mechanism of structure/composition gradients in FGM by combining multiple in-situ and ex-situ electrochemical and spectroscopic characterization tools; (2) studying the roles of structure/composition gradient of FGM in improving the LIBs durability, understanding the effects of structure/composition gradients on the electrical and electrochemical properties of electrode materials; and (3) understanding the electrode protection mechanism of FGM, establishing approaches to probe the structural and compositional reconstruction of FGM for durable LIBs.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.

对于许多最先进的应用，例如远程电动汽车和大型智能电网，对高性能和可靠的储能技术的需求越来越不断增加。可靠性和可环性是这些市场当前LIBS技术中最关键的瓶颈之一。通常，电极材料的组成和结构不稳定性是导致可靠性问题的最遇到的问题。提高电极稳定性的最新方法是使用不均匀涂层层保护电极表面。但是，在电极/涂层层界面上产生的内部电阻对性能具有负面影响。 该项目将研究FGM在LIBS中对于下一代储能技术的可控合成和电化学稳定性。该项目还包括与当地高中的相关课程发展，本科研究经验和外展计划。该项目旨在了解锂电池（LIB）电极的界面稳定机制，并通过可控的表面重建，并建立用于耐用Libs的功能分级材料（FGM）的实验方法。该项目将使用原位同步加速器X射线表征技术来识别FGM涂层电极中的电池化学，配位几何形状和相变行为。该项目将通过将高级特征与电化学分析整合在一起，全面访问FGM与LIB的加工结构 - 性能关系。研究目标将通过以下目标来实现：（1）通过结合多个原位和原位电化学和光谱特征工具来了解FGM中结构/组成梯度的形成机理； （2）研究FGM的结构/组成梯度在改善Libs耐用性中的作用，了解结构/组成梯度对电极材料电气和电化学性质的影响； （3）了解FGM的电极保护机制，建立方法，以探测FGM对耐用LIBS的结构和组成重建。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的审查标准来通过评估来通过评估来提供支持的。
