Entropy‐Driven Hydrated Eutectic Electrolytes with Diverse Solvation Configurations for All‐Temperature Zn‐ion Batteries

Batteries always encounter uncontrollable failure or performance decay under extreme temperature environments, which is largely limited by the properties of electrolytes. Herein, an entropy-driven hydrated eutectic electrolyte (HEE) with diverse solvation configurations is proposed to expand the operating temperature range of Zn-ion batteries. The HEE possesses over 40 types of Zn
