Characterizations. Morphological and elemental distribution analyses were employed using scanning electron microscope (SEM, ZEISS Gemini 450), Focused Ion Beam-Scanning Electron Microscope (FIB-SEM, Thermo Scientific Helios 5 UC), and transmission electron microscope (TEM, ThermoFisher Scientific Talos F200X G2). Material composition was determined via X-ray diffraction (XRD, Rigaku Smartlab 9kW XG) using Cu Kα radiation with a scanning speed of 8° per minute and a scanning step of 0.01°. X-ray photoelectron spectroscopy (XPS, PHI 5000 VersaProbe Ⅲ) was conducted to investigate the bonding condition of N, C, and the valence state of Zn. X-ray absorption near edge structure (XANES) measurements were operated at the Hefei Synchrotron Radiation Facility. Electrochemical measurements. The electrochemical measurements were conducted using 2032-type coin cells within a glove box (Mikrouna) filled with argon gas (H2O and O2 < 0.01 ppm). Assembly of the coin cells utilized a 16 μm thick polyethylene (PE) separator (Shanghai Enjie). Galvanostatic charge-discharge experiments were performed using a battery testing system (Wuhan LAND), while electrochemical impedance spectroscopy (EIS) was carried out using the Gamry Interface 1010E electrochemical workstation. The Gamry Echem Analyst software facilitated the impedance responses analysis and fitting of experimental data to equivalent circuit models.
