Inevitable　dissolution　in　aqueous　electrolytes,　intrinsically　low　electrical　conductivity,　and　sluggish　reaction　kinetics　have　significantly　hampered　the　zinc　storage　performance　of　vanadium　oxide-based　cathode　materials.　Herein,　core–shell　N-doped　carbon-encapsulated　amorphous　vanadium　oxide　arrays,　prepared　via　a　one-step　nitridation　process　followed　by　in　situ　electrochemical　induction,　as　a　highly　stable　and　efficient　cathode　material　for　aqueous　zinc-ion　batteries　(AZIBs)　are　reported.　In　this　design,　the　amorphous　vanadium　oxide　core　provides　unobstructed　ions　diffusion　routes　and　abundant　active　sites,　while　the　N-doped　carbon　shell　can　ensure　efficient　electron　transfer　and　greatly　stabilize　the　vanadium　oxide　core.　The　assembled　AZIBs　exhibit　remarkable　discharge　capacity　(0.92 mAh cm−2　at　0.5 mA cm−2),　superior　rate　capability　(0.51 mAh cm−2　at　20 mA cm−2),　and　ultra-long　cycling　stability　(≈100%　capacity　retention　after　500　cycles　at　0.5 mA cm−2　and　97%　capacity　retention　after　10 000　cycles　at　20 mA cm−2).　The　working　mechanism　is　further　validated　by　in　situ　X-ray　diffraction　combined　with　ex　situ　tests.　Moreover,　the　fabricated　cathode　is　highly　flexible,　and　the　assembled　quasi-solid-state　AZIBs　present　stable　electrochemical　performance　under　large　deformations.　This　work　offers　insights　into　the　development　of　high-performance　amorphous　vanadium　oxide-based　cathodes　for　AZIBs.　©　2023　Wiley-VCH　GmbH.
