Mechanistics of Lithium Metal Electrodes for High-Performance Rechargeable Batteries

Interdisciplinary Areas: Engineering and Healthcare/Medicine/Biology, Future Manufacturing

Project Description

Current lithium-ion batteries (LIBs) suffer from moderate energy density, limited cycle life, and safety issues. Lithium (Li) metal has received huge attention as a promising anode candidate due to its high theoretical capacity, the lowest negative potential, and its potential as next-generation energy storage devices (such as Li-S and Li-O2 batteries), where Li metal electrode is essential for the system. However, systemic issues, which are mainly associated with Li dendritic growth and unstable solid electrolyte interphase (SEI) layer, result in poor electrochemical performances and safety problems (e.g. short-circuit). We plan to study lithium dendrite suppression mechanisms via interfacial ion-flux control for high-capacity Li metal anodes. This will include fundamental understanding of the morphology-transport-interface interactions via a combined approach including high-resolution computational modeling, electrochemical experiments and materials chemistry.
