The development of all-solid-state rechargeable batteries based on lithium (Li) metal plating and stripping has highlighted a grand challenge: Li metal is chemically highly corrosive and mechanically stressful to the surrounding solid components, causing both electrochemical and mechanical instabilities. This project includes fundamental research to design a solid-state battery architecture in which Li metal functions as “a working fluid” rising and falling during electrochemical cycling with minimal electrochemical corrosion and mechanical stress generation. Insights from this project will potentially result in safer and higher density all-solid-state Li-metal batteries. Further, in this project a diverse group of students will be trained in a multidisciplinary setting and enhance underrepresented minority groups involvement and participation in science and engineering in general and mechanoelectrochemistry in particular at Penn State and MIT. Li metal is a soft crystal and exhibits either solid-like displacive behavior or fluid-like diffusive behavior. Li metal is also chemically aggressive, causing decomposition of solid electrolytes, consumption of active Li inventory, and uncontrollable growth of solid-electrolyte interphase. Li-metal anodes thus face stress-corrosion cracking under dual aggressive chemical and mechanical driving forces, making stable contact against Li metal challenging. To overcome these limitations, this project aims to construct a three-dimensional (3D) Li-metal host made of mixed ionic-electronic conductors (MIECs) and electronic and Li-ion insulators (ELIs). The project will develop design principles for the 3D MIEC/ELI based battery through integrated multi-faceted experimental characterization and multiscale computational modeling. Experimentally, in-situ transmission electron microscopy (TEM) will be carried out to directly observe Li deposition/stripping in the composite structure and scale up to battery-cell level testing. Computationally, molecular dynamics and multi-field continuum-level models will be coupled to simulate Li deposition/stripping and identify the dominant interfacial processes. Such an in-depth characterization and understanding will offer guidance to the optimization of the 3D MIEC/ELI based Li-metal batteries with improved cycling performance.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.

基于锂（Li）金属电镀和剥离的全固态可充电电池的发展突出了一个巨大的挑战：Li金属对周围的固体部件具有高度的化学腐蚀性和机械应力，导致电化学和机械不稳定性。该项目包括设计固态电池架构的基础研究，其中锂金属在电化学循环过程中作为“工作流体”上升和下降，电化学腐蚀和机械应力产生最小。该项目的见解可能会导致更安全，更高密度的全固态锂金属电池。此外，在该项目中，将在多学科环境中对不同的学生群体进行培训，并加强代表性不足的少数群体对科学和工程的参与，特别是在宾夕法尼亚州立大学和麻省理工学院的机械电化学。金属锂是一种软质晶体，表现出类似固体的位移行为或类似流体的扩散行为。Li金属也具有化学侵蚀性，导致固体电解质的分解、活性Li库存的消耗以及固体电解质界面的不可控生长。因此，锂金属阳极在双重侵蚀性化学和机械驱动力下面临应力腐蚀开裂，使得与锂金属的稳定接触具有挑战性。为了克服这些限制，该项目旨在构建由混合离子电子导体（MIEC）和电子和锂离子绝缘体（ELI）制成的三维（3D）锂金属主体。该项目将通过综合多方面的实验表征和多尺度计算建模，为基于3D MIEC/ELI的电池开发设计原则。在实验上，将进行原位透射电子显微镜（TEM），以直接观察复合结构中的Li沉积/剥离，并扩大到电池单元级测试。在计算上，分子动力学和多场连续水平模型将耦合到模拟锂沉积/剥离，并确定占主导地位的界面过程。这种深入的表征和理解将为基于3D MIEC/ELI的锂金属电池的优化提供指导，以改善循环性能。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
