高密度能量的锌空气电池是下一代储能技术的理想储能装置。然而，电池的性能在很大程度上依赖于空气电极中氧气电催化剂的效率。本论文制备了N、F、B三元掺杂碳纤维(TD-CFs)，并通过高效的4E(-)转移机制对氧还原反应表现出了比单一掺氮碳纤维更高的催化性能。更重要的是，构建了以TD-CFS为空气正极催化剂的一次电池和可充电锌空气电池。与使用铂/C+RuO2和Vulcan XC-72炭黑催化剂的电池相比，TD-CFS催化电池在长时间的充放电循环中表现出显著的可逆性和稳定性。
Zinc-air batteries with high-density energy are promising energy storage devices for the next generation of energy storage technologies. However, the battery performance is highly dependent on the efficiency of oxygen electrocatalyst in the air electrode. Herein, the N, F, and B ternary doped carbon fibers (TD-CFs) are prepared and exhibited higher catalytic properties via the efficient 4e(-) transfer mechanism for oxygen reduction in comparison with the single nitrogen doped CFs. More importantly, the primary and rechargeable Zn-air batteries using TD-CFs as air-cathode catalysts are constructed. When compared to batteries with Pt/C + RuO2 and Vulcan XC-72 carbon black catalysts, the TD-CFs catalyzed batteries exhibit remarkable battery reversibility and stability over long charging/discharging cycles.
