LEAPS-MPS: Investigating Ion-transport and Dynamics in Composite Materials Containing Large Boron-rich Anion (LBRA) Salts

该奖项全部或部分由《2021年美国救援计划法案》（公法117-2）资助。在这个项目中，由数学和物理科学理事会资助，位于化学部门，约瑟夫·特普罗维奇教授和他在加州州立大学北岭分校（CSUN）的学生将进行研究，旨在提高我们对电解质组合的理解，从而开发出效率更高、寿命更长的锂离子电池。Teprovich教授还将在CSUN的课程中加入一门新课程，以教育不同群体的学生关于能源化学的知识，他将促进研究经验，这些研究经验与代表性不足的学生在STEM领域的理想职业选择直接相关。Teprovich教授将系统地研究大硼富阴离子（LBRA）作为电解质系统中PF6-和其他常见阴离子的替代品，目的是了解和实现高阳离子的平移迁移率，同时降低阴离子的平移迁移率。两种方法，纳米离子不稳定和阴离子捕获，将被用来最小化LBRA的平移迁移率。CSUN是一所西班牙裔服务机构（HIS）和亚裔美国人、美洲原住民、太平洋岛民服务机构（AANAPISI），提出了一项扩大参与的计划，该计划以未被充分代表的少数族裔（URM）学生群体为中心。扩大参与计划的一个主要特点是为当地高中生开发暑期STEM课程。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。

This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2). In this project, funded by the Mathematical and Physical Sciences Directorate and housed in the Chemistry Division, Professor Joseph Teprovich and his students at California State University Northridge (CSUN) will perform studies that aim to improve our understanding of electrolyte combinations so that lithium-ion batteries that are more efficient and have longer lifetimes can be developed. Prof. Teprovich will also incorporate a new course into the curriculum at CSUN in order to educate a diverse group of students about the Chemistry of Energy, and he will facilitate research experiences that are directly related to desirable career choices in STEM for underrepresented students.Professor Teprovich will systematically investigate large boron-rich anions (LBRA) as alternatives for PF6- and other common anions in electrolyte systems, with the goal of understanding and achieving high cation translational mobility while simultaneously reducing anion translational mobility. Two approaches, nanoionic destabilization and anion trapping, will be used to minimize the translational mobility of the LBRA. A plan for broadening participation is presented that is centered around the high underrepresented minority (URM) student populations at CSUN, which is both a Hispanic Serving Institution (HIS) and an Asian American, Native American, Pacific Islander-Serving Institution (AANAPISI). A main feature of the broadening participation plan is development of a summer STEM program for local high school students.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.
