Abstract

See full text

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.
