The　development　of　appropriate　cathode　materials　with　stable　structures　and　fast　diffusion　kinetics　of　zinc　ions　is　crucial　for　aqueous　zinc-ion　batteries　(AZIBs)　but　remains　significantly　challenging.　Herein,　the　design　and　synthesis　of　defect-rich　and　prismatic-shaped　nanohybrids　composed　of　vanadium　oxynitride　nanoparticles　confined　in　the　porous　nitrogen-doped　carbon　framework　(VNxOy@NC)　are　reported.　Its　unique　structural　advantages,　including　enriched　defect　sites　that　effectively　enhance　electrical　conductivity,　accelerate　charge　transfer　kinetics,　and　improve　structural　stability.　Additionally,　the　introduction　of　structural　defects　in　VNxOy@NC　increases　the　adsorption　energy　and　reduces　the　hopping　barrier　of　Zn　ion,　as　evidenced　by　density　functional　theory　(DFT)　calculations.　The　H+　and　Zn2+　co-insertion/extraction　mechanism　was　systematically　validated　by　ex-situ　X-ray　diffraction　and　ex-situ　X-ray　photoelectron　spectroscopy　tests.　Consequently,　the　VNxOy@NC//Zn　batteries　exhibit　an　exceptional　capacity　of　570.9　mAh·g−1　at　0.2　A·g−1,　a　superior　rate　capability　of　446.7　mAh·g−1　at　20　A·g−1,　and　long　cycling　life.　Furthermore,　the　corresponding　quasi-solid-state　battery　delivers　an　ultra-high　energy　density　of　271.9　Wh·kg−1,　demonstrating　potential　for　practical　applications.　This　work　presents　an　effective　structural　and　defect　engineering　strategy　for　designing　advanced　electrode　materials　with　promising　applications　in　AZIBs.　Graphic　abstract:　(Figure　presented.)　©　Youke　Publishing　Co.,Ltd　2025.
