CAS: Electrochemical Processes of Chelated Metals

在该项目中，由化学部化学结构，动力学机制B计划资助，科罗拉多大学博尔德分校化学系的Michael Marshak教授正在开发用于电网规模长期储能的新材料。电网规模的储能是一个长期存在且未得到满足的需求，以支持风能和太阳能等间歇性能源的可持续发电。液流电池为提供廉价的能量存储提供了一个引人注目的工程框架，因为它们允许独立缩放其功率转换和能量存储组件。该项目支持金属螯合物材料作为液流电池中可持续和可扩展的储能材料的基本电化学行为的研究。该项目还支持电池化学领域新的教育和推广计划的发展，目标是在清洁能源技术领域创造一个有竞争力和公平的美国劳动力队伍。该项目的目标是提供对一大类金属螯合物配位络合物的基本分子理解，以及对这些化学现象的评估，以提高系统级液流电池的性能。这种理解将通过评价有机螯合物抑制水裂解反应的能力和测试其性能极限来实现。然后，这种方法将扩展到开发可以进行多电子氧化还原反应的金属螯合物，这可以进一步提高液流电池系统的能量密度和性能。该项目代表了一种新的方法来解决能源存储领域的长期挑战，其低成本材料在经济上是可行的，可用于大规模部署。此外，该项目不仅可以证明为实现高压水电池带来变革，但是，使用螯合物对水分解的分子抑制也可以对控制其他电化学和电催化应用（如电化学燃料生产）中的析氢反应产生更广泛的影响。该奖项反映了NSF的法定使命，并通过使用基金会的知识产权进行评估，被认为值得支持。优点和更广泛的影响审查标准。

In this project, funded by the Chemical Structure, Dynamics & Mechanisms B Program of the Chemistry Division, Professor Michael Marshak of the Department of Chemistry at the University of Colorado Boulder is developing new materials for grid-scale long duration energy storage. Grid-scale energy storage is a longstanding and unmet need to support the sustainable production of electricity from intermittent sources such as wind and solar. Flow batteries offer a compelling engineering framework for providing inexpensive energy storage because they permit independent scaling of their power conversion and energy storage components. This project supports investigation of the fundamental electrochemical behavior of metal chelate materials as sustainable and scalable energy storage materials in flow batteries. This project also supports the development of new education and outreach programs in battery chemistry, with the goal of creating a competitive and equitable US workforce in clean energy technologies.The goal of the project aims to provide a fundamental molecular understanding of a broad class of metal chelate coordination complexes, coupled with the evaluation of these chemical phenomena to improve system level flow battery performance. This understanding will be accomplished through the evaluation of the ability of organic chelates to inhibit water splitting reactions and test its performance limits. This approach will then be expanded to develop metal chelate complexes that can undergo multi-electron redox reactions, which can further increase the energy density and performance of the flow battery systems. This project represents a new approach to address longstanding challenges in the field of energy storage with low-cost materials that are economically feasible for wide scale deployment. Moreover, this project not only could prove transformative for enabling high-voltage aqueous batteries, but the molecular inhibition of water splitting using chelates could also carry wider implications for controlling hydrogen evolution reactions in other electrochemical and electrocatalytic applications such as electrochemical fuel production.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.
