    Trapping negative charges in polymer electrolytes using a frog‐shaped, ether‐functionalized anion (EFA) is presented by H. Zhang, J. Carrasco, M. Armand, and co‐workers in their Communication on page 12070 ff. The bis(trifluoromethanesulfonyl)imide anion (TFSI), shown as a slippery tadpole, is highly mobile in poly(ethylene oxide) (PEO) matrix. In contrast, the ethylene oxide legs in EFA endow trapping interactions between the anion and PEO, which suppresses mobility (Artwork: Scixel, J. Carrasco, H. Zhang, M. Armand).
