    Abstract: The present disclosure concerns a method for the preparation of lithium thiophosphate, as well as the products obtainable by said methods, and uses thereof especially as solid electrolytes. The method includes preparing a lithium thiophosphate including at least one step for the preparation of a solution S1 at a temperature T1 from −200° C. to 10° C. followed by a step for removing at least a portion of the solvent from solution S1 to obtain lithium thiophosphate. The solution S1 includes a solvent and at least P species under the form of (PS4)3−, Li species under the form of Li+, and remaining sulfur under the form of polysulfide. followed by a step for removing at least a portion of the solvent from said solution S1 to obtain lithium thiophosphate.

    Abstract: Disclosed herein are electrolyte compositions comprising a fluorinated solvent, at least one silyl oxalate represented by the formulas RR′Si(C2O4), wherein R and R′ are each the same or different from each other and independently selected from C1-C8 alkyl, C2-C8 alkenyl, C2-C8 alkynyl, or C6-C10 aryl radical, optionally comprising at least one substituent selected from halogen, hydroxyl, alkoxy, carbonyl, and carboxyl groups; and LiPF6. Also disclosed herein are electrolyte compositions comprising a fluorinated solvent and a lithium oxalato phosphate salt represented by the formula LiPF(6-2q)(C2O4)q, wherein q is 1, 2 or 3; wherein the oxalato phosphate salt comprises at least a portion that is derived from at least one silyl oxalate as defined herein. The electrolyte compositions are useful in electrochemical cells, such as lithium ion batteries.

    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.
