Non-Technical SummaryUnderstanding the principles of how ions move into lithium-ion battery electrodes is crucial in making reliable and safe batteries that store energy by storing lithium. However, big knowledge gaps remain in the understanding of how these principles apply to other ions such as potassium, sodium, and magnesium; all of these ions are crucial components of exciting next-generation batteries. This project, supported by the Solid State and Materials Chemistry program at NSF, introduces ultra-thin electrodes, which are composed of a few atom-thick flat layers of carbon, so-called few-layer graphene (FLG), as a platform for identifying problems during the storage of a broad range of ions. Because FLG is so thin, experiments can be performed very quickly. On this project researchers use techniques for seeing through FLG easily, and perform reliable quantum calculations mimicking their behavior. This allows them to swiftly evaluate ion storage performance and to learn fundamental principles impacting battery systems at large. This project aligns to NSF's mission of promoting the progress of science and advancing national prosperity by creating new knowledge on strategic materials for energy storage, such as batteries. This helps the USA to remain at the forefront of science. In order to contribute towards these greater objectives, the PI and co-PI, both identifying with Hispanic communities, offer programs that enrich and make a positive impact on student's learning and scientific life. This is achieved by providing direct educational and research opportunities to undergraduate and K-12 audiences through laboratory experiences and training, and through computational and social media resources. Technical SummaryThe goal of this project, supported by the Solid State and Materials Chemistry program at NSF, is to address challenges in the fundamental understanding of interfacial phenomena faced during ion intercalation on graphitic hosts. While several studies have addressed lithium intercalation kinetics and mechanisms, comparatively fewer have done so on other alkali ions, anions, and multivalent cations. The scope of this project is to use a versatile platform consisting of few-layer graphene (FLG) electrodes which enable high-fidelity, fast, and efficient electrochemistry to address this knowledge gap in a timely manner. FLG electrodes improve experimental throughput with true interfacial selectivity, allowing to swiftly identify and overcome interfacial kinetic barriers. Studies are complemented with insightful compositional analysis, in situ characterization, and robust quantum simulation methods for providing a deep understanding of the intercalation process. This project generates knowledge on the impact of heteroatom surface modification and ion co-intercalation on the kinetics and mechanisms of ion insertion for next generation batteries in an accelerated manner. The identification of PI and co-PI with Hispanic audiences and other underrepresented minority groups helps preparing them to tackle future challenges in energy technologies through demonstrations, laboratory experiences, and social media tools. This project aligns to NSF's mission of promoting the progress of science and advancing national prosperity by providing fundamental understanding of strategic materials for energy storage, creating transformative knowledge for allowing the USA to remain at the forefront of science, and contributing to NSF's 10 Big Ideas by growing convergence research through interdisciplinarity.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.

了解离子如何进入锂离子电池电极的原理对于制造可靠和安全的电池至关重要，这种电池通过储存锂来储存能量。然而，对于这些原理如何应用于其他离子，如钾、钠和镁，仍然存在很大的知识空白；所有这些离子都是下一代电池的关键组成部分。该项目由美国国家科学基金会固态和材料化学项目支持，引入了超薄电极，它由几个原子厚度的平面碳层组成，即所谓的少层石墨烯（FLG），作为识别大范围离子存储过程中的问题的平台。由于FLG非常薄，实验可以非常快速地进行。在这个项目中，研究人员使用技术很容易地看穿FLG，并进行可靠的量子计算来模拟它们的行为。这使他们能够快速评估离子存储性能，并了解影响电池系统的基本原理。该项目与NSF的使命一致，即通过创造关于储能战略材料（如电池）的新知识，促进科学进步和国家繁荣。这有助于美国保持在科学的前沿。为了实现这些更大的目标，PI和co-PI都认同西班牙裔社区，提供丰富并对学生的学习和科学生活产生积极影响的项目。这是通过实验室经验和培训，以及通过计算和社会媒体资源，为本科生和K-12观众提供直接的教育和研究机会来实现的。该项目由美国国家科学基金会固态和材料化学项目支持，旨在解决在石墨基体上离子插入过程中所面临的界面现象的基本理解方面的挑战。虽然有一些研究已经解决了锂的嵌入动力学和机制，但相对而言，对其他碱离子、阴离子和多价阳离子的研究较少。该项目的范围是使用由少层石墨烯（FLG）电极组成的多功能平台，实现高保真、快速、高效的电化学，及时解决这一知识缺口。FLG电极通过真正的界面选择性提高了实验吞吐量，允许快速识别和克服界面动力学障碍。研究补充了富有洞察力的成分分析，原位表征和强大的量子模拟方法，以提供对插层过程的深刻理解。该项目加速了杂原子表面修饰和离子共插对下一代电池离子插入动力学和机制的影响。与西班牙裔观众和其他代表性不足的少数群体确定PI和co-PI，有助于他们通过演示、实验室经验和社交媒体工具应对未来能源技术方面的挑战。该项目符合NSF的使命，即通过提供对储能战略材料的基本理解，创造变革性知识，使美国保持在科学的前沿，促进科学进步和促进国家繁荣，并通过跨学科的融合研究为NSF的10大理念做出贡献。该奖项反映了美国国家科学基金会的法定使命，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。
