Pancake-Like MOF Solid-State Electrolytes with Fast Ion Migration for High-Performance Sodium Battery

A pancake-like morphology solid-like eletrolyte of sodium battery with high ionic conductivity (6.60 × 10–4 S cm−1) was obtained by simple hydrothermal method.Solid-like electrolyte with pancake-like morphology showed good interface contact and excellent compatibility (stable cycle over 500 h at 0.6 mA cm−2) with sodium metal.Provides possible repulsive force explanation for the restriction of ion transport by MOF.
