The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project is to address fire and explosion safety hazards associated with lithium ion (Li-ion) battery energy storage technologies. Fueled by growth in the energy storage and electric vehicle industries, the Li-ion battery market is expected to grow to a size of several hundred billion dollars by 2025. Future viability of these clean energy technologies are dependent on Li-ion battery technology. However, Li-ion batteries occasionally catastrophically fail, posing thermal hazards as serious as fires and explosions. The proposed technology has the potential to be an effective, low cost solution and accelerating adoption of transformative clean energy technologies.This SBIR Phase I project proposes to improve the safety of Li-ion bateries. Under certain scenarios, Li-ion batteries can fail, resulting in an exothermic release of flammable and toxic gases. For applications including large multi-cell battery systems in energy storage and vehicle use, the risk of thermal runaway can result in catastrophic fires, explosions and toxic gas release that can damage nearby infrastructure and cause injury or death. Thermal runaway poses significant challenges for available suppression and mitigation systems because the hazardous gas release can continue despite suppression of the incipient fire. The proposed thermal runaway protection and suppression technology addresses the source of the hazards by exploiting a series of novel physio-chemical processes to reduce flammable and toxic gas species concentrations released during a thermal runaway event.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）项目的更广泛的影响/商业潜力是解决与锂离子（Li-Ion）电池储能技术相关的火灾和爆炸安全危害。随着能源和电动汽车行业的增长，锂离子电池市场预计到2025年将增长到数亿美元。这些清洁能源技术的未来可行性取决于锂离子电池技术。但是，锂离子电池偶尔会发生灾难性失败，构成像火和爆炸一样严重的热危害。 提出的技术有可能成为有效的，低成本的解决方案，并加速采用变革性清洁能源技术。该SBIR I期项目提议提高锂离子的安全性。在某些情况下，锂离子电池可能会发生故障，从而导致易燃气体的放热释放。对于包括大型多电池电池系统在能源存储和车辆使用中的应用，导热失控的风险可能会导致灾难性的火灾，爆炸和有毒气体释放，这些气体可能会损害附近的基础设施并造成伤害或死亡。热失控对可用的抑制和缓解系统构成了重大挑战，因为尽管抑制了初期火灾，但危险气体释放仍可以继续。提议的热失控保护和抑制技术通过利用一系列新型的理化过程来解决危害的根源，以减少在热失控事件期间释放的易燃性和有毒气体物种浓度。这项奖项反映了NSF的法定任务，并通过使用基金会的知识优点和广泛影响来评估NSF的法定任务，并被认为是值得通过评估的支持。
