The Cover Feature shows a battery cell consisting of the bilayered‐V₂O₅ 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//V₂O₅ battery.More information can be found in the Article by X. Liu et al.

封面功能显示了一个由双层V ₂ O ₅阴极，钾金属阳极和高浓度KTFSI _0.45：glyme电解质组成的电池。由于高浓度电解质中游离甘醇二糖分子的比例低，电解质本身的阳极分解和Al集电器的溶解（腐蚀）被大大降低，甚至被抑制，从而导致K //的循环能力提高。 V ₂ O ₅电池。更多信息，请参见X. Liu等人的文章。
