Porous, 3D anode materials are fabricated from Sb/Sb 2 O 3 by D.‐H. Nam, H.‐S. Kwon, and co‐workers using a simple electrodeposition method with a polypyrrole nanowire network as the substrate. On page 2885, the improved electrochemical performance of the Sb/Sb 2 O 3 –PPy electrode is attributed to the highly porous nature of the polypyrrole substrate and also to the buffer effects of the Sb 2 O 3 matrix on the volume expansion. Good electrical contact is maintained between the nanodeposits and the polypyrrole nanowires even after 100 cycles.
