Binder-Free 3D Integrated Ni@Ni3Pt Air Electrode for Zn–Air Batteries

Journal Article


Abstract


  • Developing an air electrode with high efficiency and stable performance is

    essential to improve the energy conversion efficiency and lifetime of zinc–

    air battery. Herein, Ni3Pt alloy is deposited on 3D nickel foam by a pulsed

    laser deposition method, working as a stable binder-free air electrode for

    rechargeable zinc–air batteries. The polycrystalline Ni3Pt alloy possesses

    high oxygen-conversion catalytic activity, which is highly desirable for

    the charge and discharge process in zinc–air battery. Meanwhile, this

    sample technique constructs an integrated and stable electrode structure,

    which not only has a 3D architecture of high conductivity and porosity

    but also produces a uniform Ni3Pt strongly adhering to the substrate,

    favoring rapid gas and electrolyte diffusion throughout the whole energy

    conversion process. Employed as an air electrode in zinc–air batteries, it

    exhibits a small charge and discharge gap of below 0.62 V at 10 mA cm−2,

    with long cycle life of 478 cycles under 10 min per cycle. Furthermore,

    benefitting from the structural advantages, a flexible device exhibits

    similar electrochemical performance even under the bending state. The

    high performance resulting from this type of integrated electrode in this

    work paves the way of a promising technique to fabricate air electrodes for

    zinc–air batteries.
