Patent

CA 2489953

A battery (10) having a current collector (20) constructed of carbon foam. The carbon foam includes a network of pores (41) into which a chemically active paste is disposed to create either a positive or negative plate for the battery. The carbon foam resists corrosion and exhibits a large amount of surface area. The invention includes a method for making the disclosed carbon foam current collector used in the battery.

L'invention concerne un accumulateur (10) comprenant un collecteur de courant (20) en mousse de carbone. La mousse de carbone comprend un réseau de pores (41) dans lequel une pâte chimiquement active est disposée pour créer soit une plaque positive soit une plaque négative pour l'accumulateur. La mousse de carbone résiste à la corrosion et présente une grande zone superficielle. L'invention concerne un procédé de production du collecteur de courant en mousse de carbone utilisé dans l'accumulateur.
