Li-Zn Overlayer to Facilitate Uniform Lithium Deposition for Lithium Metal Batteries.
Abstract
The highly reactive nature and rough surface of Li foil can lead to the uncontrollable formation of Li dendrites when employed as an anode in a lithium metal battery. Thus, it could be of great practical utility to create uniform, electrochemically stable, and "lithiophilic" surfaces to realize homogeneous deposition of Li. Herein, a LiZn alloy layer is deposited on the surface of Li foil by e-beam evaporation. The idea is to introduce a uniform alloy surface to increase the active area and make use of the Zn sites to induce homogeneous nucleation of Li. The results show that the alloy film protected the Li metal anode, allowing for a longer cycling life with a lower deposition overpotential over a pure-Li metal anode in symmetric Li cells. Furthermore, full cells pairing the modified lithium anode with a LiFePO<sub>4</sub> cathode showed an incremental increase in Coulombic efficiency compared with pure-Li. The concept of using only an alloy modifying layer by an in-situ e-beam deposition synthesis method offers a potential method for enabling lithium metal anodes for next-generation lithium batteries.
