The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project arises from bringing new materials to market for making improved rechargeable lithium ion batteries needed by the high-tech economy, medicine, and the military (batteries are the second largest military consumable). In today's world, everything, including medical devices (e.g., wireless implants and sensors), has an app; using apps requires batteries. This project will produce "Safer Energy for the Wireless World"; the resulting improved batteries will incorporate novel, lighter, and safer (no overheating) anode materials that will charge faster and store more energy than current versions. The new anode materials are estimated upon success to yield sales of $1B during the first 10 years from selling the materials to battery manufacturers to incorporate, initially, as composites in lithium ion battery anodes, and, later, as the entire active anode. Broader societal impacts include greater safety because the batteries do not overheat; lighter, more portable devices with longer battery life and faster recharging time; reduced need for backup batteries; and diverse STEM workforce development though applied research and entrepreneurship training.This SBIR Phase I project proposes to develop safer, more powerful ways to charge electronic devices by translating fundamental research from university to industry. The opportunity arises from an NSF-supported discovery of the first solid form of carbon monoxide known, a two-dimensional crystal structure: graphene monoxide (GmO). GmO and its first proposed application for anodes in lithium ion batteries are patented. Knowledge gaps to be addressed include identifying tailored materials for optimizing batteries for electronics, using theoretical and experimental approaches to identify the maximum energy storage capacity for lithium batteries, and determining the energy and power densities and safety properties under normal and extreme operating conditions. The technology must be demonstrated in 200-mAh pouch batteries, the first milestone needed for battery manufacturers to consider adopting the innovation through licensing or sales. The second milestone is to scale up materials to produce large quantities. The overall goal is to commercialize the GmO material into an active anode or additive material for extreme batteries. In sum, the project will yield prototype batteries made from the new materials, optimize properties for specific partner applications, simulate interactions between GmO and Li, and identify pathways for scaleup of materials production.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.

该小企业创新研究 (SBIR) 项目的更广泛影响/商业潜力源于将新材料推向市场，用于制造高科技经济、医药和军事所需的改进可充电锂离子电池（电池是第二大军用消耗品）。在当今世界，一切事物，包括医疗设备（例如无线植入物和传感器），都有一个应用程序；使用应用程序需要电池。该项目将产生“无线世界更安全的能源”；由此产生的改进电池将采用新颖、更轻、更安全（不会过热）的阳极材料，与当前版本相比，充电速度更快，储存更多能量。新阳极材料预计在成功销售给电池制造商的前 10 年内将实现 10 亿美元的销售额，最初作为锂离子电池阳极的复合材料，后来作为整个活性阳极。更广泛的社会影响包括更高的安全性，因为电池不会过热；更轻、更便携的设备，具有更长的电池寿命和更快的充电时间；减少对备用电池的需求；通过应用研究和创业培训进行多样化的 STEM 劳动力发展。SBIR 第一阶段项目建议通过将大学的基础研究转化为工业界，开发更安全、更强大的电子设备充电方式。这个机会源于美国国家科学基金会 (NSF) 支持的对已知第一种固体一氧化碳的发现，即二维晶体结构：一氧化石墨烯 (GmO)。 GmO 及其首次提出的锂离子电池阳极应用已获得专利。需要解决的知识差距包括确定用于优化电子电池的定制材料，使用理论和实验方法确定锂电池的最大能量存储容量，以及确定正常和极端操作条件下的能量和功率密度以及安全特性。该技术必须在 200mAh 软包电池中进行演示，这是电池制造商考虑通过许可或销售采用该创新所需的第一个里程碑。第二个里程碑是扩大材料规模以实现大批量生产。总体目标是将 GmO 材料商业化为极端电池的活性阳极或添加剂材料。总之，该项目将生产由新材料制成的原型电池，优化特定合作伙伴应用的性能，模拟 GmO 和 Li 之间的相互作用，并确定材料生产规模扩大的途径。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。
