A composite material (10) including two sheets of carbon foam (11, 13) laminated together using a bonding material (12), which may permeate pores (14) of both sheets of carbon foam. The bonding material may include an insulating material or a conductive material. The composite material can be configured to serve as a current collector (20) for battery (100). To form the positive and negative plates of a battery, chemically active paste is disposed on the composite current collector. The carbon foam composite material resists corrosion and exhibits a large amount of surface area. |
