The broader impact/commercial potential of this Partnership for Innovation – Technology Translation (PFI-TT) project comes from the development of additives that provide an immediate boost in battery capacity without introducing any changes to their manufacturing scheme. The lack of affordable higher-capacity batteries is recognized as a barrier to the broad utilization of, for instance, electric vehicles and renewable energy sources. Improved batteries are needed to support a transition to a greener and more sustainable society. The development of additives that can be easily integrated in current battery designs will facilitate their implementation and future commercialization, giving them a crucial advantage at a time when the battery market is both rapidly expanding and becoming increasingly competitive. This NSF PFI-TT grant will support technological validation and the development of prototypes for field-testing, both necessary step towards successful commercialization. The PI will leverage both the existing close collaboration with the Entrepreneurial Proof of Concept and Innovation Center (EPIC) and the presence of a large population of students from under-represented minorities at UCR Riverside, an accredited Hispanic Serving Institution, to provide unique training opportunities not only in science and engineering but also in entrepreneurship.The proposed project will target additives based on silicon, which, while having much higher lithiation capacity than broadly utilized graphite, has yet to be adopted by battery manufacturers on a large scale. This is due to both technical (silicon alone has poor stability over many charge-discharge cycles) and economic (silicon can be made stable but this requires complex designs) issues. This project will overcome these limitations. A simple, single-stage carbon coating step enables the integration of silicon powders into graphite-dominant anodes. Careful control of the process parameters allows realizing a high-quality carbon coating, which is crucial for the successful utilization of the additives. By developing a “drop-in” additive, this technology enables an increase in battery capacity without requiring any capital intensive investment for the battery manufacturers. As part of this project, this core technology will be advanced and the results in terms of capacity improvement and cycle stability will be validated by independent testing facilities. By the completion of this project, battery prototypes that incorporate silicon-based additives will be field-tested under real-life conditions.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.

这种创新合作伙伴关系的更广泛的影响/商业潜力 - 技术翻译（PFI-TT）项目来自添加剂的开发，这些添加剂可以立即提高电池容量，而无需对其制造计划进行任何更改。缺乏负担得起的高容量电池被认为是电动汽车和可再生能源的广泛利用的障碍。需要改进的电池以支持向更绿色，更可持续的社会过渡。可以轻松整合到当前电池设计中的成瘾性的发展将有助于其实施和将来的商业化，从而在电池市场既快速扩展又变得越来越有竞争力的时候具有至关重要的优势。这项NSF PFI-TT赠款将支持技术验证和原型开发用于现场测试的原型，这既是成功商业化的必要步骤。 PI将利用现有的概念和创新中心（EPIC）（EPIC）的现有密切合作以及来自UCR Riverside中代表不足的少数群体的大量学生的存在，UCR Riverside（一个经过认证的西班牙裔美国人服务机构），不仅在科学和工程中提供了较高的培训机会，还可以在较高的培训中提供较高的项目。容量比广泛使用的石墨，尚未大规模采用电池制造商。这是由于技术（仅硅在许多电荷释放周期上的稳定性）和经济性（可以使硅的稳定性稳定，但这需要复杂的设计）引起的。该项目将克服这些局限性。一个简单的单阶段碳涂层步骤使硅粉整合到石墨占主导地位的阳极中。仔细控制过程参数可以实现高质量的碳涂层，这对于成功利用添加剂至关重要。通过开发“倒入”添加剂，该技术可以增加电池容量，而无需为电池制造商提供任何资本密集型投资。作为该项目的一部分，该核心技术将提高，并且在能力提高和周期稳定性方面的结果将通过独立的测试设施来验证。通过完成该项目的完成，将结合基于硅的添加剂的电池原型将在现实生活中进行现场测试。该奖项反映了NSF的法定任务，并通过使用该基金会的知识分子和更广泛的影响评估标准来评估NSF的法定任务。
