Abstract

Summary: Tremendous research has focused on the wearable electronic device, leading to the basic requirement of suitable power sources. Herein, we report one bendable paper‐based zinc‐air battery with a novel hollow channel structure. It achieves a maximum power density of 138 mW/cm 2, outperforming the state‐of‐art paper‐based batteries reported previously. The boosted performance is assigned to the low charge transfer resistance and facilitated mass transfer from the hollow structure. It demonstrates the positive design of microchannel structure is profitable for the power‐generation enhancement, and offers a possible route to commercialize the paper‐based power generators. Abstract : A bendable paper‐based zinc‐air battery is fabricated with a novel hollow channel structure. It achieves a peak power density of 138 mW/cm 2, outperforming previous paper‐based power sources. The novel structure can efficiently lower charge transfer resistance and facilitate mass transfer process.
