SBIR Phase II: Development of a Flow Battery Using Common Materials and Proprietary Electrolytes

这个小型企业创新研究（SBIR）第二阶段项目的更广泛的影响/商业潜力是开发电网规模的电池，以实现大规模，长时间的能量存储。需要新的长期储能技术来解决可再生能源不稳定性的挑战。广泛部署一种基于普遍存在的廉价化学物质的新电池技术，该技术由低成本和高通量的可制造电池材料制成，将有助于社会实现气候目标，并加强美国的制造业和能源独立。此外，未来的能源格局显然具有巨大的商业潜力。目前，美国电网的储能容量不到每日发电量的0.01%。在全球范围内，到2030年，实现气候目标的估计储能需求为15太瓦时。这意味着新兴技术将带来1.3万亿美元的市场机会。该SBIR第二阶段项目建议使用高度稳定的专有电解质和从SBIR第一阶段奖项收集的知识设计和制造原型电池系统，该奖项验证了电荷存储解决方案在与廉价电池制造材料（塑料，橡胶和复合材料）接触时的稳定性。该项目将验证全尺寸电池、电池堆和系统的性能，并最终交付一个能够输出1千瓦10小时的电池系统。交付的1 kW/10 kWh系统将具有更长的使用寿命（20年以上），并证明比目前可用的液流电池更低的成本，将代表朝着公用事业规模储能系统的发展迈出的重要一步。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。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is the development of a grid-scale battery to enable large-scale, long-duration energy storage. New technologies for long-duration energy storage are required to solve the challenge of renewable energy intermittency. The widespread deployment of a new battery technology based on ubiquitous and inexpensive chemistry that is fabricated from low-cost and high-throughput manufacturable cell materials will help society achieve climate goals and bolster American manufacturing and energy independence. Additionally, the energy landscape of the future clearly presents enormous commercial potential. US grid storage capacity today is less than 0.01% of daily generation. Globally, the estimated energy storage needs to meet climate goals is 15 Terawatt hours by 2030. This translates to a market opportunity of $1.3 trillion to be fulfilled by emerging technologies. This SBIR Phase II project proposes to design and fabricate a prototype battery system using highly stable, proprietary electrolytes and knowledge gathered from an SBIR Phase I award that verified the stability of charge storage solutions when in contact with inexpensive cell fabrication materials (plastics, rubbers, and composites). This project will validate performance in full-scale cells, stacks and systems, and culminate in the delivery of a battery system capable of outputting 1 kW for 10 hours. The delivered 1 kW/10 kWh system will have a longer lifetime (20+ years) and demonstrated lower cost than current flow batteries available today and will represent a significant step towards the development of a utility scale energy storage system.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.
