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

该奖项全部或部分根据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，并设在化学部，教授约瑟夫Teprovich和他的学生在加州州立大学北岭（CSUN）将进行研究，旨在提高我们的电解质组合的理解，使锂离子电池更有效，寿命更长，可以开发。 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了解能源化学，并为代表性不足的学生提供与STEM理想职业选择直接相关的研究经验。Teprovich教授将系统地研究大型富硼阴离子（LBRA）作为电解质系统中PF 6-和其他常见阴离子的替代品，目的是理解和实现高阳离子平移迁移率，同时降低阴离子平移迁移率。两种方法，nanoionic去稳定和阴离子捕获，将用于最大限度地减少LBRA的平移迁移率。 一个扩大参与的计划，是围绕高度代表性不足的少数民族（URM）的学生群体在CSUN，这既是一个西班牙裔服务机构（HIS）和亚裔美国人，美洲原住民，太平洋岛民服务机构（AANAPISI）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夏季STEM项目。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。

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.
