摘要： Preparation of an electrolyte film for lithium/polymer electrolyte batteries by extruding a powder mixture containing a polymer, a lithium salt and an additive consisting of an ultra fine powder of a metal oxide, such as silica, aluminum, or titanium oxide with a particle size between about 7 and 40 nm. The role of the additive is to prevent the formation of adhesive solid blocks in the powder mixture and to allow the introduction of this mixture in the extruder. Electrolyte compositions, electrolytes as well as electrochemical generators obtained according to the invention are also described.

摘要： A solvent of the polymer-salt complex and a non-solvent thereof are added to the solvent used in the polymer synthesis, to provide a lower and an upper phase. The lower phase contains substantially all the polymer in the solvent of the polymer-salt complex. It is separated from the upper phase and the salt is added to the lower phase to constitute a solution of the electrolyte.

摘要： Peeling of an LPB amorphous electrolyte from its coating substrate or protective film is carried out by introducing a non-polar solvent, based on at least one aliphatic or cycloaliphatic hydrocarbon containing about 5 to 15 carbon atoms, between the electrolyte and its substrate or protective film. It is thus possible to suddenly and easily separate the substrate or the protective film from the electrolyte without pulling off any amount thereof.

摘要： To prepare polymer dispersions containing large quantities of solid particles, with at least some of these consisting of materials with a high specific area (>50 m.sup.2 /g) or oil absorption capacity, the mixture of particles is first co-ground in a non polar solvent. The co-ground mixture is dried until obtaining a dry powder of reagglomerated particles, which is dispersed in a solution containing a polymer and possibly a salt. Large quantities of solid particles can thus be dispersed while maintaining adequate rheological properties for the dispersion, and low porosities and few surface defects in the films obtained by coating the dispersion. This process can be used to prepare thin films of positive electrode for lithium polymer batteries, as well as in the paint, coatings and magnetic tape industry.
摘要翻译：为了制备含有大量固体颗粒的聚合物分散体，其中至少一些由具有高比表面积（> 50m 2 / g）的材料或吸油能力组成，首先将颗粒混合物以非极性共研磨溶剂。将共混混合物干燥直到获得再聚集的颗粒的干燥粉末，其分散在含有聚合物和可能的盐的溶液中。因此，可以分散大量的固体颗粒，同时保持分散体的足够的流变性能，并且通过涂布分散体获得的薄膜中的低孔隙率和很少的表面缺陷。该方法可用于制备锂聚合物电池正极的薄膜，以及涂料，涂料和磁带行业中的薄膜。
