Abstract

To meet the ever-increasing demand of multifarious electronics and electrified vehicles, developing stable and high-performance electrodes for aqueous rechargeable nickel–zinc (Ni//Zn) batteries is highly attractive. Herein, Ni3S2@polyaniline (PANI) core–shell nanosheets with excellent electrochemical performance and superior cycling stability have been successfully developed as a new robust binder-free cathode for rechargeable Ni//Zn batteries. Benefiting from the enhanced charge transport rate, the as-fabricated Ni3S2@PANI//Zn battery presents an impressive specific capacity of 242.8 ± 8.8 mA h g−1 at a current density of 5.1 A g−1 with no capacity decay after 5000 cycles. Additionally, the aqueous rechargeable Ni3S2@PANI//Zn battery shows a promising energy density of 386.7 W h kg−1, together with a peak power density of 38.8 kW kg−1. Such a glorious stable Ni3S2@PANI cathode for Ni//Zn batteries may provide significant insight into future multifarious electronics and electrified vehicle applications.
