Abstract: The present invention concerns a process for manufacturing a porous carbonaceous monolith structure comprising the steps of (i) introducing a precursor material comprising particles comprising a halogenated polymer having a melting point in a mold; (ii) forming a shaped body comprising aggregates of the particles of the precursor material, by concurrently applying to the precursor material a pressure P ranging from 10 to 300 bars when the halogenated polymer is a vinylidene chloride homopolymer and from 10 to 150 bars when the halogenated polymer differs from a vinylidene chloride homopolymer, and maintaining the precursor material at a temperature T1 ranging from T1,min=20° C. to T1,max=Tm−50° C. wherein Tm is the melting point of the halogenated polymer, and; (iii) optionally cooling then demolding the shaped body; (iv) introducing the shaped body in a furnace; (v) causing the pyrolysis of the halogenated polymer in the furnace until the porous carbonaceous monolith structure is obtained.

Abstract: The present invention relates to a process for manufacturing a free-standing solid composite electrolyte film, comprising the steps of a) mixing (i) at least one sulfide-based solid ionic conducting inorganic particle and (ii) at least one tetrafluoroethylene (TFE) (co)polymer to form a paste and b) calendaring or extruding the paste to produce a film. The invention also relates to a free-standing solid composite electrolyte film comprising (i) at least one sulfide-based solid ionic conducting inorganic particle and (ii) at least one TFE (co)polymer, wherein an amount of the (ii) at least one TFE (co)polymer is from 1.0 to 20.0 wt %, preferably from 2.0 to 15.0 wt % and more preferably from 3.0 to 10.0 wt %, based on the total weight of the film.
