Abstract The industrial development of Zn‐ion batteries requires high performance even with lean‐electrolyte. Nevertheless, lean‐electrolyte can exacerbate concentration polarization at the interface electrode/electrolyte, leading to significant Zn corrosion and battery failure. Here, a stable ion‐rich protective layer (TMAO‐Zn) is constructed by unique zwitterion structure trimethylamine N‐oxide (TMAO). TMAO characterized direct connection between positive negative charges (N + ‐O − ) minimal dipole moment, which renders weak interactions form TMAO‐Zn 2+ , thereby reducing promoting rapid uniform deposition . Furthermore, O exhibits higher electrophilic index, indicating stronger propensity for hydrogen bond active free water in inner Helmholtz (IHL), mitigating under extreme conditions low electrolyte‐to‐capacity ratio (E/C ratio). Consequently, symmetrical enables cycling over 250 h 15 µL mA −1 Additionally, Zn/I₂ pouch E/C 21.2 provides ultra‐high specific capacity 96 cycles (capacity retention rate 98.3%). This study offers new concept propel practical application
