STTR Phase I: Thermal Runaway and Pressure Suppression (TRAPS) for Lithium-Ion Batteries

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/商业潜力是开发和商业化一种技术，以减轻与电动汽车、运输和储能应用中锂离子（Li-ion）电池技术相关的安全问题。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。在储能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。锂离子电池技术在储能市场的采用受到安全问题的阻碍，即火灾和爆炸危险。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、被动的解决方案，以减轻这些危害，并减轻这些担忧。该技术在能源储存和运输行业具有很高的市场渗透率，并将使采用变革性技术成为可能，推动我们走向更绿色、更可持续的能源未来。这项小型企业技术转让（STTR）第一阶段项目将探索和开发被动降低锂离子电池火灾和爆炸危险的技术。对于能源存储、车辆应用等领域的大型多电池系统，这些危险可能会破坏附近的基础设施，并造成伤害或死亡。锂离子电池会发生自热故障，即释放可燃气体的热失控现象。热失控对现有的火灾和爆炸抑制系统提出了重大挑战，因为即使抑制了初期火灾，气体释放也会继续不减。目前的缓解办法只处理火灾的后果，而没有解决危害的根本原因，即易燃气体的产生。这里的方法是开发技术来减轻危害的根本原因，并降低电池气体的可燃性。显然有必要增加对热失控环境中危险气体和可燃气体被动缓解机制的科学认识。该项目的总体目标是进一步科学地理解这些被动缓解技术，并展示锂离子电池应用的概念验证性能。该奖项反映了美国国家科学基金会的法定使命，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) 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.
