  • Abstract:
    Rechargeable composite polymer batteries are disclosed employing composite polymer electrolytes comprising an inorganic oxide, exemplified by fumsilic(SiO), and an organic polymer, exemplified by poly(vinylidene fluoride)-hexafluoropropene copolymer (PVDF-HFP), gelled with Li-ion battery electrolytes. The composite polymer electrolytes are prepared by forming a suspension of the inorganic oxide in a solution of the organic polymer contained in a suitable carrier solvent, spraying the suspension onto the surfaces of Li-ion battery electrodes to form inorganic oxide-organic polymer composite films that adhere to the electrode surfaces, and gelling the films with Li-ion battery electrolytes in-situ to form composite inorganic oxide-organic polymer gel electrolytes. Li-ion battery cells are then constructed with the resulting electrode-polymer electrolytes.

  • International Classification:
    H01M010/40
  • US Classification:
    429/188000, 429/330000, 429/338000, 429/342000, 429/326000, 429/339000, 429/340000
  • Abstract:
    Thermally stable electrolytes for Li-ion batteries obtained with the use of Lewis base additives to the electrolytes are disclosed. The Lewis bases stabilize electrolytes composed of solutions of LiPFin organic carbonates against decomposition at temperatures as high as 85 C. Additives suitable for stabilizing LiPF-containing electrolytes include amines, for example, triethylenediamine (TEDA) and 2,2′-bipyridine (BIPY), phosphines, for example, triphenylphosphine (TPP) and tributylphosphine (TBP), and nitrogen-phosphorus bonded compounds such as hexamethoxycyclotriphosphazene ([N P(OCH)]) (HMOPA), hexamethyl phosphoramide (HMPA), and N-phenyl-P,P,P-trimethylphosphorimidate (PhTMI). These additives are also capable of stabilizing electrolytes in solvents other than carbonates including ethers, esters and sulfones.
