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.

该小型企业创新研究 (SBIR) 第二阶段项目的更广泛影响/商业潜力将是提供一种更经济、可扩展和可持续的电池类型，用于存储支持美国不断增长的可再生能源电网所需的能源。随着太阳能发电的安装，越来越需要经济形式的能源存储来在无风和无阳光的时期提供电力，由于供应、安全、长寿，该项目旨在生产新的化学成分，以实现基于可回收锌金属的电网规模电池，这提供了更安全、更可持续的替代电网规模电池选择。此外，由于锌及其其他电池成分来自于。美国，这个项目可能有助于促进国内电池制造，减少对国外电池供应的依赖。SBIR第二期提出了生产化学添加剂的项目，使锌溴电池寿命更长、储存更多能量、运行更高效，从而可以提供可持续的低成本可再生能源存储目前，此类电池的主要问题与电池充电过程中发生的不良电化学副反应有关，该项目将通过稳定、可扩展的有机电解质添加剂来消除这些副反应，以防止锌表面出现问题。在该项目的这一阶段，电池制造商将通过在实际电池和全尺寸电池中进行测试来对这些电解质添加剂进行修改和优化，以实现新型电解质的性能和可扩展性。或许大量可用，以帮助建立安全、可持续、国产的锌溴电池。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
