Abstract: The present invention relates generally to the field of the storage of electrical energy in all-solid-state batteries, in particular in storage batteries of Li-ion type. More specifically, the invention relates to a solid electrolyte consisting of a polymer matrix and of a fibrous reinforcement which makes possible the manufacture of a non-porous film exhibiting a very good compromise between ion conductivity, electrochemical stability, high-temperature stability and mechanical strength. This film is intended for an all-solid-state battery separator application, in particular for Li-ion batteries. The invention also relates to an all-solid-state battery comprising such a separator and/or such an electrolyte.
