Battery including carbon foam current collectorsUS2004002006A1

摘要

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 resist corrosion and exhibits a large amount of surface area. The invention includes a method for making the disclosed carbon foam current collector used in battery.
