A separator for battery and including a plate shaped structure of inorganic fibers is distinguished in that said separator is impregnated with a dispersion of colloidal inorganic nano particles that have been enriched in the crossing points of the fibers when solvent has been dried so as to form binding agent. The invention also concerns a battery including such a separator with high pressure on the active material and a method for producing such a separator.
L'invention concerne un séparateur de batterie, comprenant une structure sous forme de plaque de fibres inorganiques. Ce séparateur se caractérise par le fait qu'il est imprégné à l'aide d'une dispersion colloïdale de nanoparticules inorganiques enrichies au niveau des points d'intersection entre les fibres une fois qu'un solvant a séché, pour former un liant. L'invention concerne également une batterie comprenant ce séparateur monté avec une pression élevée sur la matière active, ainsi qu'un procédé servant à la production de ce séparateur.
