摘要:
Polymer electrolyte for an electrochemical generator based on at least a four branched polymer, at least a poly(vinylyldienefluoride), a poly(vinyldiene fluoro-co-hexafluoropropene copolymer), a poly(tetrafluoroethylene), a poly(ethylene-co-propylene-co-5-methylene-2-norbornene) or an ethylene propylene-diene copolymer, a polyol, a poly(methylmethacrylate, a poly(acrylonitrile), SiO2Al2O3, or nano TiO2 non coated or coated with an organic material. This electrolyte allows to prepare electrolytic compositions that can be used in high performance electrochemical devices.

摘要:
The invention concerns a method for preparing ceramic powders in the presence of a carbon powder comprising a step which consists in homogenizing a mixture of particles capable of resulting in a ceramic by heat treatment. Said method can be carried out in the presence of an accelerated solvent and provides, at reduced energy consumption, carbon-coated ceramic powders and then ceramics.
摘要:
The invention relates to a method of preparing an electrochemical electrode which is partially or totally covered with a film that is obtained by spreading an aqueous solution comprising a water-soluble binder over the electrode and subsequently drying same. The production cost of the electrodes thus obtained is reduced and the surface porosity thereof is associated with desirable resistance values.

摘要:
A multilayer material includes a solid substrate and at least two superimposed solid layers containing particles of an electrochemically active material, the first solid layer adhering to the solid substrate and the second solid layer adhering to the first solid layer. The multilayer material has a constant thickness of upper layer not less than 95% and a depth of penetration of the second layer into the first layer which is less than 10% of the thickness of the first layer, and enables as electrode constituent, generators having a low risk of overload degradation to be prepared.
