    摘要： 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.

    摘要： 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.
