The Cover Feature illustrates ionic liquids based on potassium bis(trifluoromethanesulfonyl) amide (KTFSA) salt in 1‐methyl‐1‐propylpyrrolidinium bis(trifluoromethanesulfonyl)amide (Pyr 13 TFSA), which can serve as feasible electrolytes for safe operation at high‐voltage conditions for potassium‐ion batteries. Electrochemical measurements reveal a wide voltage tolerance, indubitably suggesting KTFSA‐based ionic liquids as potent and stable electrolytes for high‐voltage cathode materials (such as the honeycomb layered tellurates) for high‐performance potassium‐ion batteries. More information can be found in the Article by K. Yoshii et al. on page 3901 in Issue 15, 2019 (DOI: 10.1002/celc.201900689).
