The broader impact/commercial potential of this I-Corps project is the development of technologies to help deepen transportation electrification and widely implement renewable clean energies for decarbonizing our society to achieve sustainable prosperity. The success of this project will further accelerate technology transfer, increase economic competitiveness, and help the United States remain a leading position in new energies. There is an urgent desire worldwide on transportation electrification. The key lies in a robust high energy rechargeable battery to power electric vehicles, which is expected to satisfy the following requirements: a high energy density for a driving range of ≥300 miles, an affordable cost, reliable safety free of fires and explosions, and a long lifetime. The proposed technology has the potential to meet all these requirements and surpasses the current lithium-ion battery technologies.This I-Corps project is based on the development of high-energy anode-free lithium-metal batteries, which consists of an anode current collector and a lithiated cathode. The high performance of this battery is based on the innovative atomic and molecular layer deposition technology of the team for novel functional nanocoatings. These nanocoatings are applied onto the anode current collector and the lithiated cathode and result in remarkably improved performance. Lithium-ion batteries have changed our lifestyles in many aspects but are approaching their energy limit. They also suffer from some other issues related to cost, lifetime, and safety. Consequently, all these drawbacks of lithium-ion batteries have stimulated new battery concepts while anode-free lithium-metal batteries are among the most compelling ones. Anode-free lithium-metal batteries have the potential to maximize battery energy density, minimize battery cost, and remarkably improve battery safety.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/商业潜力是开发技术，旨在帮助加深运输电气化并广泛实施可再生的清洁能源，以使我们的社会脱碳以实现可持续的繁荣。该项目的成功将进一步加速技术转移，提高经济竞争力，并帮助美国在新能量中仍然是领先地位。全世界在运输电气化方面都有急需的愿望。关键在于强大的高能量可充电电池对电动汽车的电动汽车，预计将满足以下要求：高能密度≥300英里，负担得起的成本，可靠的安全性，没有火灾和爆炸的可靠安全以及一生。所提出的技术有可能满足所有这些要求并超过当前的锂离子电池技术。此I-Corps项目基于高能无阳极无锂金属电池的开发，该电池由阳极电流收集器和有限的阴极组成。该电池的高性能是基于新型功能纳米涂层团队的创新原子和分子层沉积技术。将这些纳米涂料应用于阳极电流收集器和有限的阴极上，并导致性能明显提高。锂离子电池在许多方面都改变了我们的生活方式，但正在接近其能量限制。他们还遭受了与成本，终身和安全有关的其他一些问题。因此，锂离子电池的所有这些缺点都刺激了新的电池概念，而无阳极金属电池是最引人注目的电池。无阳极金属电池有可能最大程度地提高电池能量密度，最大程度地降低电池成本并显着提高电池安全性。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响评估标准来评估值得支持。
