All-solid-state lithium batteries using lithium metal as an anode are attractive candidates for high energy density energy storage systems, because the lithium metal offers a high specific capacity of 3,862 mAh g-1. The protection of lithium metal and the control of the lithium electrode/electrolyte interface are very important for developing the all-solid-state lithium batteries with good capacity retention and enhanced safety. In our work, we report a protection of the lithium metal by coating ion-conductive polymer layer, which allows lithium cation diffusion and inhibits the dendrite formation. Electrochemical properties of the surface-modified Li electrode are investigated by linear sweep voltammetry, DC polarization and electrochemical impedance spectroscopy. |
