Unraveling the Complexities of Li Metal and Its Interfaces for Solid State Batteries

Popis výsledku v původním jazyce

Li-metal anodes are a key enabling technology for next-generation high-energy batteries, including Li–S, Li-air, and high-voltage cathodes. While most research enabling Li metal focuses on electrolyte design, especially in the solid state, the nature of the Li metal itself has a significant impact on the performance of both solid- and liquid-based batteries. Recent work has highlighted that both the microstructure and the surfaces of Li metal can vary dramatically from source to source. This presentation will detail how the Li surfaces, impurities and microstructure all play a role in the performance of Li metal with both liquid and solid electrolytes. Equally important to Li metal batteries is the nature of the interface between the electrolyte and Li metal. In solid state batteries these interfaces are especially difficult to characterize due to their buried nature. The second half of this presentation will focus on the use of neutron reflectometry and neutron depth profiling to characterize buried solid-state electrolyte-Li metal interfaces. The focus will be on using the solid electrolyte LiPON as an example, but also extend to polymers and other oxide ceramics.
