Abstract: Ionically conductive materials that can be used in electrochemical generators. A new ionically conductive material usable in an electrochemical generator, for example in separators, solid polymer electrolytes or electrodes, has good mechanical properties and good ionic conductivity and is able to prevent dendritic growth in lithium batteries. The material comprises at least one polymer A, different from B, having an ionic conductivity of between 10?5 and 10?3 S/cm, at least one polymer B having mechanical strength characterised by a storage modulus ?200 MPa and at least one reinforcing filler C.

Abstract: The invention relates to ionically conductive materials that can be used in electrochemical generators. The aim of the invention is to provide a new ionic ally conductive material that can be used in an electrochemical generator, for example in separators, solid polymer electrolytes or electrodes, has good mechanical properties and good ionic conductivity and is able to prevent dendritic growth in lithium batteries. Said material comprises: 1. at least one polymer A, different from B, having an ionic conductivity of between 10?5 and 10?3 S/cm, 2. at least one polymer B having mechanical strength characterised by a storage modulus ?200 MPa, for example of between 200 and 5000 MPa or between 350 and 1500 MPa; and 3. at least one reinforcing filler C. The invention also relates to films based on said type of material and to methods for the synthesis of said films.
