A Leap toward Quasi-Solid-State Chloride-Ion Batteries with Metal-Organic Frameworks.

ABSTRACT: The development of solid-state electrolytes is a major focus in energy storage, offering improvements in both safety and performance. In chloride-ion batteries (CIBs), where electrode dissolution in liquid electrolytes remains a critical challenge, solid-state alternatives are especially attractive. Herein, we demonstrate for the first time the suitability of a metal-organic framework (MOF) as a quasi-solid-state single-ion electrolyte for CIBs. The cationic Al-based MOF MIP-213 ([Al₁₈(μ₂-OH)₂₄(OH₂)₁₂(mdip)₆]-6Cl·6H₂O) exhibits a chloride ion conductivity of 1.1 × 10^-6 S cm^-1 at 25 °C, is nonflammable, electrochemically stable up to 4.2 V vs Li⁺/Li, and enables single-ion transport
