Abstract

A battery having a current collector constructed of carbon foam. The carbon foam includes a network of pores into which a chemically active material 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.
