这个小型企业创新研究(SBIR)或STTR第一阶段项目的更广泛的影响/商业潜力是开发一项技术并将其商业化，以缓解电动汽车、交通运输和储能应用中与锂离子(Li-ion)电池技术相关的安全担忧。锂离子电池技术是过去十年中最具变革性的创新之一，并将继续为未来的技术发展提供平台。锂离子电池技术的潜在市场规模是巨大的。在能源储存和电动汽车行业增长的推动下，锂离子电池市场预计到2025年将增长到1000亿美元以上。由于安全问题，即火灾和爆炸危险，锂离子电池技术在储能市场的采用受到阻碍。在这个第一阶段项目中开发的技术有可能成为一种低成本的被动解决方案，以减轻这些危险，并缓解这些担忧。这项技术有可能在能源储存和运输行业具有很高的市场渗透率，并将使人们能够采用变革性技术，推动我们走向更绿色、更可持续的能源未来。这个小型企业技术转移(STTR)第一阶段项目将探索和开发被动缓解锂离子电池火灾和爆炸危险的技术。对于能量储存、车辆应用等领域的大型多电池电池系统来说，这些危险可能会破坏附近的基础设施，并导致人员伤亡。锂离子电池可能会发生一种称为热失控的自热故障，会释放出易燃气体。热失控给现有的灭火和爆炸灭火系统带来了巨大的挑战，因为尽管初期的火灾被扑灭了，但气体的释放仍然可以有增无减。目前的缓解办法针对火灾的后果，而没有解决危险的根本原因，即产生易燃气体。这里的方法是开发技术来缓解危险的根本原因，并降低电池气体的可燃性。显然需要增加对热失控环境中危险气体和易燃气体被动缓解机制的科学认识。该项目的总体目标是促进对这些被动缓解技术的科学理解，并展示锂离子电池应用的概念验证性能。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势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) or STTR Phase I project is to develop and commercialize a technology to mitigate safety concerns associated with lithium-ion (Li-ion) battery technologies in electric vehicle, transportation, and energy storage applications. Li-ion battery technology is one of the most transformative innovations in the past decade and continues to provide a platform for future technology development. The potential market size for Li-ion battery technology is substantial. Fueled by growth in energy storage and electric vehicle industries the Li-ion battery market is expected to grow to over US$100 billion by 2025. Adoption of Li-ion battery technology in the energy storage market being impeding by safety concerns, namely fire and explosion hazards. The technology to be developed in this Phase I project has the potential to be a low-cost, passive solution to mitigate these hazards, and alleviate these concerns. The technology has potential to have high market penetration in energy storage and transportation industries, and will enable adoption of transformative technologies that pushes us toward a greener and more sustainable energy future. This Small Business Technology Transfer (STTR) Phase I project will explore and develop technology for passive mitigation of Li-ion battery fire and explosion hazards. For large multi-cell battery systems in energy storage, vehicle applications and among others, these hazards can damage nearby infrastructure and cause injury or death. Li-ion batteries can undergo a self-heating failure called thermal runaway that releases flammable gases. Thermal runaway poses significant challenges for available fire and explosion suppression systems because the gas release can continue unabated despite suppression of the incipient fire. Current mitigation approaches treat the consequences of the fire and do not address the root cause of the hazard, namely the production of flammable gases. The approach here is to develop technology to mitigate the root cause of the hazard and reduce the flammability of the battery gases. There is a clear need to increase the scientific understanding of passive mitigation mechanisms of hazardous and flammable gases in the thermal runaway environment. The overall objective of this project is to further the scientific understanding of these passive mitigation techniques and demonstrating proof-of-concept performance for Li-ion battery applications.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.
