dc.description.abstract | Rational construction of flexible free-standing electrocatalysts featuring long-lasting durability, high efficiency, and wide temperature tolerance under harsh practical operations are fundamentally significant for commercial zinc-air batteries. Here, 3D flexible free-standing bifunctional membrane electrocatalysts composed of covalently cross-linked supramolecular polymer networks with nitrogen-deficient carbon nitride nanotubes are fabricated (referred to as PEMAC@NDCN) by a facile self-templated approach. PEMAC@NDCN demonstrates the lowest reversible oxygen bifunctional activity of 0.61 V with exceptional long-lasting durability, which outperforms those of commercial Pt/C and RuO2. Theoretical calculations and control experiments reveal the boosted electron transfer, electrolyte mass/ion transports, and Calalysta abundant active surface site preferences. Moreover, the constructed alkaline Zn-air battery with PEMAC@NDCN air-cathode reveals superb power density, capacity, and discharge-charge cycling stability (over 2160 cycles) compared to the reference Pt/C+RuO2. Solid-state Zn-air batteries enable a high power density of 211 mW cm(-2), energy density of 1056 Wh kg(-1), stable charge-discharge cycling of 2580 cycles for 50 mA cm(-2), and wide temperature tolerance from - 40 to 70 degrees C with retention of 86% capacity compared to room-temperature counterparts, illustrating prospects over harsh operations. | en_US |
