Lithium-sulfur (Li-S) batteries are currently being explored intensely due to their high theoretical specific energy density and low cost [1]. However, the area] sulfur loading of electrodes is usually less than 2.0 mg cm~(-2), which leads to low areal capacity that does not even outperform standard Li-ion batteries (4 mAh cm~(-2)) [2]. For conventional aluminum-based sulfur electrodes, it is almost impossible to obtain high sulfur loaded electrodes by increasing the electrode thickness, because thick electrode will cause low sulfur utilization as a result of limited electrode kinetics for both lithium ions and electrons [3]. In this regard, using three-dimensional (3D) current collectors with interlinked electron and ion channels will be ideal for achieving high sulfur-loaded and high performance Li-S batteries.
