The broader impact/commercial potential of this I-Corps project is the development of technology applied to the ever-growing sectors of consumer products, transportation, and biomedical devices that rely on portable and flexible power. The lithium-ion battery market has already reached a valuation of $44 billion in 2021, driven by both consumer demand and government legislature. This project seeks to offer a step forward via battery components that are safer than conventional batteries in that they are immune to explosions and fires, offer flexible properties, and all the while improve performance (e.g., electric vehicle driving range). This I-Corps project is based on the development of technology that improves both the performance and safety of current lithium-ion batteries. The unique mechanical and ionic conductivity properties of the technology’s porous, inflammable, composite nano- and micro- structures will improve the lifetime and capacity of batteries produced by electric vehicle and electric vehicle battery manufacturers, increase manufacturing due to reduced testing requirements, and remove risks of fire and explosion associated with current battery electrolyte technologies. By marrying the advantages of polymer materials (mechanical robustness, hierarchical nano- and micro-structures, scalable solution processing) with those of ceramics (improved conductivity and electrochemical stability), a state-of-the-art porous material is produced that is tougher than Kevlar with simultaneous ion transport capabilities. In the context of batteries, this material has shown higher energy densities, longer cycle life, and unprecedented safety compared to current liquid electrolyte-based lithium batteries that are known to pose significant fire and chemical risks. Furthermore, effective dendrite resistance, ultra-high ion transport, and electrochemical stability of the materials supports the improved performance and overall impact of the novel product.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I-Corps项目的更广泛的影响/商业潜力是开发依赖于便携式和柔性功率的消费产品，运输和生物医学设备不断增长的领域的技术。在消费者需求和政府立法机关的推动下，锂离子电池市场已经在2021年达到440亿美元的价值。该项目试图通过比传统电池更安全的电池组件向前迈出一步，因为它们可以免疫爆炸和火灾，提供灵活的特性，并且在改善性能（例如电动汽车驾驶范围）时。该I-Corps项目基于技术的开发，该技术可以改善当前锂离子电池的性能和安全性。该技术的多孔，易燃，复合纳米和微型结构的独特机械和离子电导率特性将改善电动汽车和电动汽车电池制造商生产的电池的寿命和容量，并因测试需求减少而增加制造，并消除与当前电池电池技术相关的火灾和爆炸风险。通过将聚合物材料的优势（机械鲁棒性，分层纳米和微结构，可扩展的溶液处理）与陶瓷（改善电导率和电化学稳定性）的优势结合在一起，可以产生一种与Simple ION ION TORMPORTION的多孔材料。在电池的背景下，与当前液体电解质锂电池相比，该材料显示出更高的能量密度，更长的循环寿命和前所未有的安全性，这些锂电池已知会带来很大的火灾和化学风险。此外，有效的树突耐药性，超高离子运输和材料的电化学稳定性支持了新产品的提高性能和整体影响。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的审查标准来评估，被认为是珍贵的支持。
