Definitions

  • the present invention relates to a composite electrolyte comprising a solid-liquid electrolyte in the form of a gel for use in electrochemical devices particularly in primary or secondary batteries, supercapacitors, electro-chromic displays or solar cells.
  • the present invention also relates to electrochemical devices comprising the composite electrolyte element and the method for their preparation.
  • Alkali metal batteries in particular lithium-ion batteries are known. They are widely used in portable electronic devices, cameras, electric tools, electric vehicles and the like.
  • R 4 is independently selected from the group consisting of CH3, CH 2 CH3, CFhCFhCFh, CFI(CFl3)2, and CFI 2 Rf, where R5 is a C1 to C3 alkyl group which is optionally substituted with at least one fluorine atom, and R3 is a C1 to C3 alkyl group substituted with at least one fluorine, and further wherein at least one of R3 or R 4 contains at least one fluorine and when R3 is CF 2 H, R 4 is not CH.
  • the precipitated silica is characterized by a BET specific surface area of from 100 to 650 m 2 /g.
  • the precipitated silica used in the present invention has an aluminium content, calculated as aluminium metal, of more than 0.25 wt%, even more than 0.30 wt% with respect to the weight of the precipitated silica.
  • the content of aluminium may conveniently be of at most 0.50 wt%.
  • the precipitated silica has a BET specific surface from 100 to 270 m 2 /g, and a median particle size from 3.0 to 80.0 pm. In some instances the median particle size may be greater than 5.0 pm, even greater than 6.0 pm.
  • the present invention provides an electronic device, in particular primary or secondary batteries, supercapacitors, electro-chromic displays or solar cells comprising the composite electrolyte as defined above. All definitions and preferences defined above for the composite electrolyte and its components equally apply to the electronic devices comprising the composite electrolyte.
  • an additional object of the invention is a pouch battery comprising a composite electrolyte comprising a non-woven layer and a solid-liquid electrolyte provided on at least one surface of said non-woven porous layer.
  • Liquid electrolyte The electrolyte was prepared by simple mixing using magnetic stirrer. All components were added to one bottle and were mixed until providing a transparent solution. Firstly, lithium hexafluorophosphate (LiPFe) was dissolved in the solvent. The solvent was composed of ethylene carbonate (EC) and ethyl methyl carbonate (EMC) in a 3:7 v/v ratio and then 2 wt% vinylene carbonate (VC). Then 0.5 wt% 1 ,3-propane sultone (PS) was added as an additive. This electrolyte was used as a reference electrolyte.
  • EC ethylene carbonate
  • EMC ethyl methyl carbonate
  • PS wt% vinylene carbonate
  • Negative electrode formulation BTR918-2 + Super-P® + SBR/CMC (97:1 :1 :1 by weight); electrode loading: 13.3 mg/cm 2 .
  • Electrolyte (C) was injected in pouch cell using a syringe and sealed under vacuum.
