The Cover Feature shows a battery cell consisting of the bilayered‐V 2 O 5 cathode, potassium metal anode, and highly concentrated KTFSI 0.45 :glyme electrolyte. Because of the low fraction of free glyme molecules in the highly concentrated electrolyte, the anodic decomposition of electrolyte itself and the dissolution (corrosion) of the Al current collectors are significantly reduced and even suppressed, leading to the improved cycling ability of the K//V 2 O 5 battery.More information can be found in the Article by X.
