Definitions

  • Lithium-ion is as follows: firstly an insertion material (for example LiCoO 2 , LiNiO 2 , LiMn 2 O 4 , LiMnO 2 or a mixture of these materials) or agglomerates of the insertion material, of dimension from 1 to 50 ⁇ m are dispersed in an organic solvent. To this dispersion is added electroconductive carbon black and a binder of the polytetrafluoroethylene or polyvinylidene difluoride type. Then the mixture is applied and squeezed onto an aluminum sheet which serves as a current collector.
  • an insertion material for example LiCoO 2 , LiNiO 2 , LiMn 2 O 4 , LiMnO 2 or a mixture of these materials
  • electroconductive carbon black and a binder of the polytetrafluoroethylene or polyvinylidene difluoride type To this dispersion is added electroconductive carbon black and a binder of the polytetrafluoroethylene or polyvinylidene difluoride
  • polyelectrolyte is understood to mean any water-soluble polymer which, in solution, carries numerous ionizable groups (at least 20% of the monomers), which induce electrostatic charges.
  • electrostatic charges along the molecular chain induces medium and short-range interactions, which gives the polyelectrolytes remarkable physicochemical properties.
  • Polyelectrolytes have many fields of application: medicine, paper, paint, food industry, cosmetics, pharmacy, water treatment ... Polyelectrolytes are used for their rheological and adsorption properties at interfaces, generally irreversible .
  • the polyelectrolyte must respond to the various constraints related to the introduction of a polymer into a Li-ion accumulator electrode, that is to say, sufficient elasticity to undergo the expansions during insertion and de-insertion cycles, stability chemical and especially electrochemical. Its potential stability window must indeed be compatible with that of the electrode considered in the battery, which depends on materials and operating potentials.
  • Amino-functional cationic polyelectrolytes are infinitely derivable.
  • synthetic polyelectrolytes are selected.
  • composition A a method of preparation may be provided in at least two steps: - dissolving the amino-functional cationic polyelectrolyte (iii) in water, and then
  • a filtration step of the composition B may be provided.
  • composition is deposited on an aluminum current collector (20 microns thick).
