Redox Oligomer Assembling Hierarchical Reinforced Framework Cathodes for Ultra‐Stable High‐Performance Zinc‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
Redox phenoxoline‐benzoquinone oligomer has been designed as reinforced concrete framework like freestanding cathodes for high‐performance ZIBs. An optimal specific capacity of 339.5 mAh g−1 was contributed with exceptional retention of 87.5% after 65 000 cycles at 10 A g−1. Flexible energy storage is also demostrated.
