摘要： The present invention relates to a lithium-ion battery element which is chosen from the separator and the electroactive layers and which results from the forming of a microcomposite powder comprising a fluoropolymer in the form of particles between 0.1 and 0.5 nullm in size and fillers. The present invention also relates to a lithium-ion battery electrode comprising the above electroactive layer combined with a metal layer. The present invention also relates to a lithium-ion battery comprising at least one element such as the separator, the electroactive layer or the electrode defined above. This microcomposite powder can be prepared by coatomization of an aqueous solution containing the fluoropolymer particles between 0.1 and 0.5 nullm in size and of an aqueous solution of the fillers. It can also be prepared by flocculation or coagulation of an aqueous solution containing the fluoropolymer particles between 0.1 and 0.5 nullm in size and of an aqueous solution of the fillers. The forming of this microcomposite powder consists in preferably forming a film in order to obtain an electrode film or a separator film. Next, these films are joined together to form a battery. This step (assembly, electrolyte filling, packaging, etc.) is known per se.

摘要： The invention relates to a method for treating a metal surface by carboxylation before forming, said metal being selected from zinc, iron, aluminium, copper, lead and the alloys thereof as well as copper-coated, aluminium-coated, galvanised steels. Said method is carried out in oxidising conditions in relation to the metal by bringing said metal into contact with an aqueous, organic or hydro-organic bath comprising at least one organic acid in free form or in salt form. The inventive method is characterised in that: the organic acid is a saturated or unsaturated aliphatic monocarboxylic or dicarboxylic acid; the organic acid is in solution and/or emulsion in the bath at a concentration greater than 0.1 mole/litre; the pH of the bath is acid.

摘要： The invention is a PVDF (polyvinylidene fluoride) homopolymer or copolymer, the comonomer being chosen from compounds containing a vinyl group capable of being opened by the action of free radicals in order to be polymerized and which contains, directly attached to this vinyl group, at least one fluorine atom, a fluoroalkyl group or a fluoroalkoxy group such that: it comprises a fraction of non-transferred chains of very high molar mass which are completely insoluble in the usual solvents for PVDF, such as DMF (dimethylformamide), DMSO (dimethyl sulphoxide) and NMP (N-methylpyrrolidone), the polymer fraction associated with these high-mass chains having a dynamic viscosity of greater than 50 kpoise at 230null C. and at a shear rate of 100 snull1, the size of the spherulites is between 0.5 and 4 nullm. The invention also relates to blends of this PVDF with an ABC triblock copolymer, the three blocks A, B and C being linked together in this order, each block being either a homopolymer or a copolymer obtained from two or more monomers, the A block being linked to the B block and the B block to the C block by means of a covalent bond or of an intermediate molecule linked to one of these blocks via a covalent bond and to the other block via another covalent bond, and such that: the A block is compatible with PVDF, the B block is incompatible with PVDF and is incompatible with the A block, the C block is incompatible with PVDF, the A block and the B block. The invention also relates to the parts made of the above composition. These parts may be sheets, films, tubes, rods, centrifugal pump components and containers. The invention also relates to a process for synthesizing this PVDF, in which: a dispersion of VF2 (vinylidene fluoride) and of one or more optional comonomers in water is made, possibly with the aid of a surfactant, the said dispersion being initially brought into contact with a water-soluble non-organic initiator capable of causing the polymerization of the monomers; then, part of the PVDF having been formed in the presence of the water-soluble non-organic initiator, the following are added: either (i) a chain transfer agent capable of propagating the polymerization, the said polymerization then being initiated by a water-soluble non-organic initiator or by an organic initiator, or (ii) an organic initiator, also capable of accomplishing chain transfer, and optionally a water-soluble non-organic initiator.

摘要： The present invention is a composition comprising by weight: 70 to 96% of at least one polyamide chosen from PA-11, PA-12, aliphatic polyamides resulting from the condensation of an aliphatic diamine having from 6 to 12 carbon atoms and an aliphatic diacid having from 9 to 12 carbon atoms, and 11/12 copolyamides having either more than 90% of nylon-11 units or more than 90% of nylon-12 units; 4 to 10% of a plasticizer; 0 to 25% of an NBR or HnullNBR elastomer; and the sum of the amount of plasticizer and the amount of elastomer is between 4 and 30%. These compositions can be manufactured by melt-blending the various constituents using standard techniques for thermoplastics. They are particularly useful for pipes used in the operation of offshore oil and gas fields. They exhibit very good ageing resistance. They are also useful for simpler pipes in motor vehicles, these compositions withstanding the ageing caused by the temperature under the bonnet of motor vehicles and the nature of the fluids transported. The invention also relates to pipes comprising at least one layer of this composition. These are either pipes used offshore or simpler pipes for motor vehicles.
