Patents Assigned to ACEP, Inc.
  • SOLVENTS AND NOVEL ELECTROLYTIC COMPOSITIONS HAVING A LARGE RANGE OF STABILITY AND HIGH CONDUCTIVITY
    Publication number: 20110128674
    Abstract: The present invention is concerned with novel polar solvents and novel electrolytic compositions comprising such solvents, and having a high range of stability, as required for applications in the field of electrochemistry. The present solvents have a highly polar amide function, and preferably combine with a salt soluble in the solvent and having an anion with a delocalized charge, and at least one polymer, to form an electrolytic composition.

  • Materials useful as electrolytic solutes
    Patent number: 7378194
    Abstract: The invention concerns novel ionic compounds with low melting point whereof the onium type cation having at least a heteroatom such as N, O, S or P bearing the positive charge and whereof the anion includes, wholly or partially, at least an ion imidide such as (FX1O)N?(OX2F) wherein X1 and X2 are identical or different and comprise SO or PF, and their use as solvent in electrochemical devices. Said composition comprises a salt wherein the anionic charge is delocalised, and can be used, inter alia, as electrolyte.
