Stable Lithium Metal Anodes with a GaO_x Artificial Solid Electrolyte Interphase in Damp Air

As a promising high energy density electrode material for rechargeable batteries, lithium (Li) metal is still suffering from air/water instability due to its highly reactive nature. In addition, the Li dendrite issue in Li metal batteries needs to be resolved to ensure the safety of batteries and for wide applications. Herein, we demonstrate that a simple compact GaOx layer formed using liquid metal (LM) can act as an artificial solid...
