Integrating Electric Ambipolar Effect for High-Performance Zinc Bromide Batteries.

ABSTRACT: The coupling of fast redox kinetics, high-energy density, and prolonged lifespan is a permanent aspiration for aqueous rechargeable zinc batteries, but which has been severely hampered by a narrow voltage range and suboptimal compatibility between the electrolytes and electrodes. Here, we unprecedentedly introduced an electric ambipolar effect for synergistic manipulation on Zn²⁺ ternary-hydrated eutectic electrolyte (ZTE) enabling high-performance Zn-Br₂ batteries. The electric ambipolar effect motivates strong dipole interactions among hydrated perchlorates and bipolar ligands of L-carnitine (L-CN) and sulfamide, which reorganized primary cations solvation sheath in a manner of forming Zn[(L-CN)(SA)(H₂O)₄]²⁺ configuration and dynamic
