Abstract

Refreshing the record of the electrocatalytic activity for bifunctional oxygen electrocatalysis is the first priority of developing next-generation rechargeable zinc-air batteries. A ΔE indicator to evaluate the bifunctional electrocatalytic activity has stagnated with a record of ΔE > 0.60 V for decades. Herein, a bifunctional oxygen electrocatalyst is developed to afford an ultrahigh bifunctional electrocatalytic activity of ΔE = 0.57 V and realize high-performance rechargeable zinc-air batteries. Specifically, atomically dispersed Fe-N-C sites and NiFeCe layered double hydroxides are integrated to afford a composite FeNC@LDH electrocatalyst, following the guidance of the data-driven analysis. The FeNC@LDH electrocatalyst demonstrates a record-breaking electrocatalytic activity of ΔE = 0.57 V, far exceeding the state-of-the-art level by ca. 60 mV. Practical ampere-hour-scale zinc-air batteries are constructed with a capacity of 6.4 Ah and cycle under 1.0 A and 1.0 Ah conditions. This work affords a record-breaking bifunctional electrocatalyst for ampere-hour-scale zinc-air batteries in future application scenarios.

一种数据驱动的双功能氧电催化剂，其用于安培小时级锌-空气电池的 ΔE = 0.57 V 值打破了记录

刷新双功能氧电催化的电催化活性记录是开发下一代可充电锌-空气电池的首要任务。几十年来，评价双功能电催化活性的 ΔE 指标一直停滞在 ΔE > 0.60 V。在此，我们开发了一种双功能氧电催化剂，使其具有ΔE = 0.57 V 的超高双功能电催化活性，并实现了高性能可充电锌-空气电池。具体来说，在数据驱动分析的指导下，将原子分散的Fe-N-C位点和NiFeCe层状双氢氧化物整合在一起，形成了FeNC@LDH复合电催化剂。FeNC@LDH 电催化剂的电催化活性达到了破纪录的 ΔE = 0.57 V，远远超出最先进水平约 60 mV。我们建造了实用的安培小时锌-空气电池，容量为 6.4 Ah，可在 1.0 A 和 1.0 Ah 的条件下循环使用。这项研究为未来应用场景中的安培小时级锌-空气电池提供了创纪录的双功能电催化剂。
