Abstract

LA PRESENTE INVENTION SE RAPPORTE A UN SEPARATEUR DE BATTERIE AYANT UNE FORTE CONDUCTIVITE ELECTRIQUE ET PRESENTANT UNE BONNE INHIBITION A LA FORMATION DE DENDRITES. SELON L'INVENTION, IL SE COMPOSE D'UNE FEUILLE FORMEE D'UN MELANGE SENSIBLEMENT UNIFORME D'UN CAOUTCHOUC THERMOPLASTIQUE, D'UNE CHARGE INERTE AYANT UNE DIMENSION GRANULOMETRIQUE MOYENNE COMPRISE ENTRE ENVIRON 0,01 ET 10M, D'UN MODIFICATEUR D'UN CAOUTCHOUC THERMOPLASTIQUE ET D'UN AGENT DE TRAITEMENT CHOISI PARMI L'ACIDE STEARIQUE, DES SELS DE METAUX DE L'ACIDE STEARIQUE, DES AMIDES DE L'ACIDE STEARIQUE, ET DES CIRES NATURELLES OU SYNTHETIQUES; CES COMPOSANTS SONT PRESENTS A UN RAPPORT VOLUMIQUE DE L'ORDRE DE 3:1:0,2:0,06 A 4:1:0,6:0,4. L'INVENTION S'APPLIQUE NOTAMMENT AUX SEPARATEURS DE BATTERIES D'ACCUMULATEURS.
