报告大纲: Beyond state-of-the-art lithium-ion battery (LIB) technology with metallic lithium anodes to replace conventional ion intercalation anode materials is highly desirable because of lithium’s highest specific capacity (3,860 mA/g) and lowest negative electrochemical potential (∼3.040 V vs. the standard hydrogen electrode). Using solid state electrolyte is one of the most promising way to address the fundamental challenges of chemical/physical short circuits in Li metal batteries, such as Li dendrite penetration anddissolved cathode materials. In this presentation, I will talk about how to use Fiber and Textile Nanotechnology to design fibrous and flexible ceramic ion conductors as solid state electrolytes for Li-metal batteries. This presentation is based on my recent work published in Nature Materials (2016), Science Advances (2017), PNAS (2016), and Energy and Environmental Science (2017).
