Abstract

Lithium metal batteries (LMB)-laminate-type full cells were prepared by combining a high-concentrated electrolytes lithium bis(fluorosulfonyl)imide (LiFSI)/ethylene carbonate (EC) and the 3-Dimensionally Ordered Macroporous (3DOM) Polyimide (PI) separator, and the cycle characteristics were compared with the full cell using the conventional polypropylene (PP) + polyethylene (PE) separator, which is widely used in lithium ion batteries. The capacity of the laminate-type cell using the PP + PE separator decreased to half of the initial capacity after 50 cycles, while the cell using the 3DOM PI separator kept its initial capacity and showed stable performance even after 50 cycles.
