Insight into the evolution of the Solid Electrolyte Interphase on Li-metal formed with a Highly concentrated Electrolyte
Metallic Lithium (Li) is the anode material with the highest theoretical specific capacity (3860 mAh/g) for future Li-batteries. Unfortunately, its practical application is severely hindered by uncontrolled growth of Li dendrites and low Coulombic efficiency which mainly results from the unstable solid electrolyte interphase (SEI) formed on the Li-metal anode. Recently, we have reported that highly concentrated electrolytes can enable ultrahigh Coulombic efficiency and cycling stability of Li-metal anodes. With this proposal, we aim to perform in-situ neutron reflectometry (NR) using a custom-built electrochemical cell to directly track the evolution of electrode/electrolyte interface in order to reveal the mechanism behind the extraordinary performance of the high concentrated electrolytes. With neutron reflectometry we can directly probe the evolution of the interfacial structure which will provide new insight on the stability of SEI on Li-metal electrodes and open new routes to rationally design electrolytes for high-energy-density battery systems.
