Part 1, non-technicalReducing greenhouse gas emissions is critical to address the grand challenge of climate change. Renewable energy integration and vehicle electrification, keys to reducing greenhouse gas emissions, require energy storage at scale with safety and low cost. This PIRE team will conduct fundamental research to advance science and technology of all-solid-state batteries (ASSBs), which have the potential to transform rechargeable batteries for vehicle electrification and integration of renewable energy by offering next-generation energy storage devices with higher specific energy at both battery-cell and battery-pack levels, longer cycle life, lower cost and superior safety compared to Li-ion batteries (LIBs). The anticipated economic benefit (reduction in the cost of battery packs on the energy base by 50% over LIBs) along with unprecedented electrochemical performance (150% increase in the specific energy) and intrinsic safety will usher in a new era of vehicle electrification and renewable energy integration for a sustainable society with clean energy. By working with international partners from 7 institutions in Europe, the researchers will achieve the challenging goal of advancing science and technology in ASSBs. Through collaboration with industrial partners, the research team will expedite technology translation from laboratory discovery to commercial products. Further, they will collaborate with several minority-serving elementary, middle and high schools in Chicago to inspire underrepresented minority students to pursue STEM education and career. By working with City of Chicago, the researchers will launch a workforce development program, offering short courses and workshops to mid-career employees and underrepresented minorities, which can accelerate transition of the workforce into clean energy, electric vehicle, and energy storage industries.Part 2, technicalTo address the multi-faceted challenges faced by ASSBs, the PIs have assembled a multi-disciplinary team and will work with international partners with synergistic expertise, particularly with Prof. Braga at University of Porto, Portugal – the inventor of a new solid Li-glass electrolyte with ultrahigh ionic conductivity at room temperature ( 10-2 S/cm), wide electrochemical window (stable with Li metal and resistant to oxidation up to 8 V vs. Li/Li+), and low glass transition temperature (~75oC). The team will investigate and integrate conventional and unconventional charge storage mechanisms to achieve ultrahigh specific energy, high power, long cycle life ASSBs with intrinsic safety. Anode-free cells with Li plating/stripping at both anode and cathode enabled by Li-glass electrolyte will be studied for the first time. The electrochemical principles for such Li plating/stripping cells and those for anode-free cells with Li plating/stripping at the anode and de/intercalation at the cathode will be established to offer guidelines for design of ASSBs with unprecedented specific energies. In-situ and ex-situ characterizations will be performed to unravel the underlying mechanisms controlling interfacial properties of ASSBs. Density functional theory calculations, molecular dynamics and continuum models will be used and integrated to address the multi-length scale modeling from the electrode/electrolyte interface to single particle, multiple particles, and eventually to cell-level responses. The atomic level, sub-continuum level and cell-level understandings developed from these modeling efforts will assist the fundamental understanding of chemical/electrochemical stability between the electrode and Li-glass electrolyte, mechanical contact, Li plating/stripping, Li dendrite formation, ionic transport, and degradation physics of ASSBs. Through these scientific advancements, this PIRE project will lay a solid foundation for design, synthesis and fabrication of high-performance ASSBs at scale in the future.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.

第1部分，非技术减少温室气体排放对于应对气候变化的巨大挑战至关重要。可再生能源集成和车辆电气化，减少温室气体排放的钥匙需要安全性和低成本的能量存储。 This PIRE team will conduct fundamental research to advance science and technology of all-solid-state batteries (ASSBs), which have the potential to transform rechargeable batteries for vehicle electrification and integration of renewable energy by offering next-generation energy storage devices with higher specific energy at both battery-cell and battery-pack levels, longer cycle life, lower cost and superior safety compared to Li-ion batteries (LIBs).预期的经济利益（将电池组在能源基础上的成本降低了50％，而不是LIB），以及前所未有的电化学性能（特定能源的提高150％）和内在的安全性将在车辆电气化的新时代和可再生能源综合时代，从而使可持续的能源与清洁能源进行可持续的能源整合。通过与欧洲7家机构的国际合作伙伴合作，研究人员将实现促进ASSB中科学和技术的挑战目标。通过与工业合作伙伴的合作，研究团队将加快从实验室发现到商业产品的技术翻译。此外，他们将与芝加哥的几所小学，中学和高中合作，以激发代表性不足的少数族裔学生从事STEM教育和职业。 By working with City of Chicago, the researchers will launch a workforce development program, offering short courses and workshops to mid-career employees and underrepresented minorities, which can accelerate transition of the workforce into clean energy, electric vehicle, and energy storage industries.Part 2, technicalTo address the Multi-faceted challenges faced by ASSBs, the PIs have assembled a multi-disciplinary team and will work with international partners with协同专业知识，尤其是葡萄牙波尔托大学的布拉加教授，这是新的固体Li-Glass电解质的发明者，具有超高离子电导率在室温下（10-2 s/cm）（10-2 s/cm），宽的电化学窗口（用LI金属稳定，具有LI金属稳定，可抗氧化，可抗氧化8 V vs. li/li/li/li/li/li+li/li+li/li li Li/li folow玻璃的过渡温度（〜7555）。该团队将调查并整合常规和非常规的电荷存储机制，以实现具有内在安全性的超高特定能量，高功率，长期寿命。 Li-Glass电解质启用的阳极和阴极均具有LI板/剥离的无阳极细胞将首次研究。将建立此类LI镀金/剥离细胞的电化学原理以及在阳极处使用LI板和剥离的无阳极细胞的电化学原理，并在阴极处建立DE/Intercalation，以提供具有前所未有的特定能量的Assb的设计指南。将执行原位和原位字符，以揭示控制ASSB的界面特性的基本机制。密度功能理论计算，分子动力学和持续模型将被使用并集成，以解决从电极/电解质界面到单个粒子，多个粒子，有时甚至细胞级响应的多长度尺度建模。这些建模工作从这些建模工作中得出的原子水平，亚爆发水平和细胞水平的理解将有助于对电极和Li-Glass电解质之间的化学/电化学稳定性，机械接触，Li Plating/剥离，Li树突形成，离子运输，离子运输和降解物理学的基本理解。通过这些科学的进步，这个PIRE项目将在未来大规模设计，合成和制造高性能的设计奠定坚实的基础。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力优点和更广泛的影响审查标准通过评估来获得的支持。
