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.

这个I-Corps项目的更广泛的影响/商业潜力是开发应用于依赖便携式和灵活电源的消费品、运输和生物医学设备等不断增长的领域的技术。在消费者需求和政府立法的推动下，锂离子电池市场在2021年的估值已经达到440亿美元。该项目旨在通过比传统电池更安全的电池组件向前迈进一步，因为它们不受爆炸和火灾的影响，提供灵活的特性，同时提高性能（例如，电动车驾驶范围）。这个I-Corps项目的基础是提高当前锂离子电池性能和安全性的技术开发。该技术的多孔、易燃、复合纳米和微米结构的独特机械和离子导电性能将提高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，由于降低了测试要求而增加了制造量，并消除了与当前电池电解质技术相关的火灾和爆炸风险。通过将聚合物材料的优点（机械坚固性、分级纳米和微米结构、可扩展的溶液处理）与陶瓷的优点（改善的导电性和电化学稳定性）相结合，生产出比Kevlar更坚固的最先进的多孔材料，同时具有离子传输能力。在电池方面，与目前已知具有重大火灾和化学风险的液体电解质锂电池相比，这种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。此外，有效的抗枝晶性、超高离子传输性和电化学稳定性支持了该新型产品的性能和整体影响的改善。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。
