Polymer dispersion composition

Composition de dispersion polymere

Abstract

Composition de dispersion polymère obtenue par mélange d'une solution aqueuse d'un polymère soluble dans l'eau avec un liquide organique dans lequel sont dispersées des particules polymères insolubles dans l'eau, puis par déshydratation du mélange. On peut utiliser cette composition, par exemple, en tant que liant pour des piles électriques au lithium. Les piles fabriquées avec cette composition possèdent une capacité importante et présentent des caractéristiques excellentes de charge et de décharge.
A polymer dispersion composition obtained by mixing an aqueous solution of a water-soluble polymer with an organic liquid containing water-insoluble polymer particles dispersed therein and then dehydrating the mixture. The composition is suitable for use, e.g., as a binder composition for lithium-ion secondary batteries. The batteries produced with the composition have a large capacity and excellent charge-discharge characteristics.
