There is a critical need for improved energy storage technologies for electric vehicles and large-scale integration of renewable electricity grid storage to improve domestic energy security. Currently, state-of-the-art energy storage technologies such as lithium ion batteries are insufficient in providing the performance requirements needed such as cost and energy density to enable broad use. Alternative battery chemistries could provide an avenue towards gains in energy density, durability, and cost for these applications. This fundamental research project addresses the use of sodium ion batteries as a potential low-cost and sustainable solution to large-scale electrochemical energy storage systems. However, the inferior cycle life of cathode electrode materials for this type of battery is a significant roadblock towards commercialization. This project addresses the issue with a collaborative experimental program that focuses on cathode electrode material synthesis methods and experimental characterization tools that can measure the processes occurring at the interface region of the cathode electrode and the battery electrolyte. Fundamental knowledge will result on these processes and will enable rational design strategies to increase the durability, energy density, and cycle life of this battery type. For broader impacts, the project's partners will establish an energy storage research program at Jackson State University. An outreach program at each project institution will be enriched with educational modules and hands on activities for elementary school-age students with a learning disability in dyslexia via summer camps and learning centers and with enhanced parent participation. This project seeks to elucidate the interfacial degradation mechanisms of sodium cathode materials and to establish experimental approaches for tailoring and strengthening the cathode?electrolyte interface for sodium-ion batteries. The project will make use of advanced synchrotron X-ray and electron characterization tools to probe the battery chemistry in the temporally and spatially resolved environments. The project will improve the electrochemical kinetics of active particles and surface stability of cathode materials and thus their performance in sodium ion batteries. There is a need for a holistic study to understand the formation and evolution of the interfacial degradation as well as to quantitatively pinpoint its relationship with the surface oxygen reactivity and bulk redox chemistry. The doping approach will simultaneously mitigate the interfacial degradation and accelerate the bulk electrochemical kinetics. The research will accomplish the following objectives: (1) probing the multiscale interfacial chemical and structural transformations and investigating the relationship between sodium cathode surface chemistry, interfacial degradation, and electrochemical kinetics, (2) conducting spectroscopic and imaging measurements to spatially quantify the influence of the interfacial degradation on the bulk redox behavior of sodium cathode particles as a function of the state-of-charge, cycling history, and charging protocol, and (3) establishing approaches to tailor the cathode surface chemistry for mitigating the interfacial degradation and improving the sodium ion battery performance (e.g. energy density, cycle life, rate capability).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.

迫切需要改进电动汽车储能技术和大规模整合可再生电网存储，以提高国内能源安全。目前，最先进的储能技术（例如锂离子电池）不足以满足广泛使用所需的性能要求（例如成本和能量密度）。替代电池化学物质可以为这些应用提供提高能量密度、耐用性和成本的途径。该基础研究项目致力于使用钠离子电池作为大规模电化学储能系统的潜在低成本且可持续的解决方案。然而，此类电池的阴极电极材料的循环寿命较差是商业化的重大障碍。该项目通过一个协作实验计划解决了这个问题，该计划侧重于阴极电极材料合成方法和实验表征工具，可以测量阴极电极和电池电解质界面区域发生的过程。基础知识将产生这些过程，并将使合理的设计策略成为可能，以提高这种电池类型的耐用性、能量密度和循环寿命。为了产生更广泛的影响，该项目的合作伙伴将在杰克逊州立大学建立一个储能研究项目。每个项目机构的外展计划将通过夏令营和学习中心以及加强家长的参与，为有阅读障碍的学习障碍小学生提供教育模块和实践活动。该项目旨在阐明钠阴极材料的界面降解机制，并建立定制和强化钠离子电池阴极电解质界面的实验方法。该项目将利用先进的同步加速器 X 射线和电子表征工具来探测时空分辨环境中的电池化学成分。该项目将改善活性颗粒的电化学动力学和正极材料的表面稳定性，从而提高它们在钠离子电池中的性能。需要进行整体研究来了解界面降解的形成和演变，并定量确定其与表面氧反应性和本体氧化还原化学的关系。掺杂方法将同时减轻界面降解并加速体电化学动力学。该研究将实现以下目标：（1）探索多尺度界面化学和结构转变，并研究钠阴极表面化学、界面降解和电化学动力学之间的关系，（2）进行光谱和成像测量，以空间量化钠阴极颗粒的本体氧化还原行为的界面退化与充电状态、循环历史和充电协议的关系，以及（3）建立定制阴极表面化学以减轻界面退化的方法该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
