The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project will be to provide a more economical, scalable, and sustainable type of battery for storing the energy needed to support America’s growing renewable power grid. As more wind and solar power generation is being installed, there is a growing need for economical forms of energy storage to supply power during windless and sunless times. Older technologies like lithium ion and lead acid batteries are not ideal for this purpose due to problems with supply, safety, longevity, and sustainability. This project seeks to produce new chemical components to enable grid-scale batteries based on recyclable zinc metal, which offers a safer and more sustainable alternative grid-scale battery option. Furthermore, since zinc and its other battery components are sourced in the US, this project may help facilitate domestic battery manufacturing and reduce dependence on foreign battery supplies.This SBIR Phase II project proposes to produce chemical additives that make zinc-bromine batteries last longer, hold more energy, and run more efficiently so that they can provide sustainable low-cost energy storage for renewable power. Presently, the major problems with these types of batteries are related to unwanted electrochemical side reactions that happen during battery charging. This project will eliminate these side reactions with stable, scalable, organic electrolyte additives designed to prevent problems at the zinc surface. During this phase of the project, these electrolyte addititives will be modified and optimized for performance and scalability. They will be evaluated via testing in actual cells and full-size batteries by the battery manufacturers. By the end of the project, new class of enabling electrolyte may be available in large quantities to help establish safe, sustainable, domestically made zinc-bromine batteries.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.

这项小型企业创新研究（SBIR）II期项目的更广泛的影响/商业潜力将是提供更经济，可扩展性和可持续性的电池类型，以存储支持美国不断增长的可再生能源电网所需的能量。随着越来越多的风力和太阳能发电的安装，在无风和无阳光时期，经济形式的储能形式的需求越来越大。由于供应，安全性，寿命和可持续性问题，锂离子和铅酸电池等较旧的技术并不理想。该项目旨在生产新的化学组件，以基于可回收锌金属的网格尺度电池，该电池可提供更安全，更可持续的替代网格尺度电池。此外，由于锌及其其他电池组件是在美国采购的，因此该项目可能有助于支持国内电池制造并减少对外国电池供应的依赖。这项SBIR II期项目的提案提出了生产化学添加剂，使锌溴电池持续更长的时间，持有更长的时间，保持更多的能源，并更有效地运行可持续的低量能源来为ReNeable提供可持续的能源。目前，这些类型的电池的主要问题与电池充电过程中发生的不良电化学侧面反应有关。该项目将使用稳定，可扩展的有机电解质添加剂来消除这些副反应，旨在防止锌表面问题。在项目的这一阶段，这些电解质添加性将被修改并优化，以进行性能和可伸缩性。电池制造商将通过实际电池和全尺寸电池进行测试对它们进行评估。到项目结束时，可以大量提供新的启用电解质类，以帮助建立安全，可持续性，国内制造的锌 - 溴电池。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的审查标准来评估NSF的法定任务。
