Flexible Quasi‐Solid‐State Composite Electrolyte Membrane Derived from a Metal‐Organic Framework for Lithium‐Metal Batteries

In this work, we developed a new kind of flexible Li‐ion conductor membrane consisting of poly(vinylidene fluoride‐co‐hexafluoropropylene) matrix and ionic liquid absorbed in metal‐organic framework (MOF) particles. This composite membrane facilitates a homogeneous Li‐ion flux and exhibits an excellent ionic conductivity of about 4.3×10 −4 S cm −1 at room temperature, a wide electrochemical window of 4.8 V ( vs . Li + /Li), as well as good...
