A Hydrogen‐Aided Rechargeable Battery

) 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.
