Abstract

Rechargeable metal–air batteries, despite their high energy density and cost‐effectiveness, suffer from sluggish cathodic reaction kinetics, resulting in high overpotential and low energy efficiency. In this study, a hydrogen‐aided battery (HAB) based on zinc–air battery (ZAB) technology, which retains the discharge process of ZAB while introducing hydrogen gas into the cathode during charging, is proposed. The introduction of hydrogen replaces the conventional oxygen evolution reaction (OER) with the hydrogen oxidation reaction (HOR), significantly enhancing the electrochemical performance of ZAB. Leveraging the faster kinetics and lower overpotential of HOR, the hydrogen‐coupled charging enables ultra‐fast and stable charging (9 s to 1 mAh cm−2) with over 200 cycles. Compared to lithium‐ion batteries and fuel cells, HAB exhibits superior safety by eliminating the need for flammable electrolytes and portable hydrogen storage devices. The simultaneous “refueling” of hydrogen and electricity offers rapid energy replenishment, positioning HAB as a transformative technology for electric vehicles to address key challenges such as range anxiety and prolonged charging durations. This work not only advances the performance of metal–air batteries but also provides an innovative strategy for integrating hydrogen energy into electrochemical systems.

氢辅助可充电电池

可充电金属-空气电池，尽管具有高能量密度和成本效益，但其阴极反应动力学缓慢，导致高过电位和低能量效率。本研究提出了一种基于锌空气电池（ZAB）技术的氢辅助电池（HAB），该电池在充电过程中保留了ZAB的放电过程，同时将氢气引入阴极。氢的引入用氢氧化反应取代了传统的析氧反应，显著提高了ZAB的电化学性能。利用更快的动力学和更低的过电位，氢耦合充电可以实现超快速和稳定的充电（9秒到1毫安时厘米−2），超过200次循环。与锂离子电池和燃料电池相比，HAB通过消除对易燃电解质和便携式储氢装置的需求，具有优越的安全性。氢气和电力的同时“加油”提供了快速的能量补充，将HAB定位为电动汽车的变革性技术，以解决诸如里程焦虑和充电时间延长等关键挑战。这项工作不仅提高了金属-空气电池的性能，而且为将氢能集成到电化学系统中提供了一种创新的策略。
