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.
Claims23
A battery comprising:
- a housing;
- a positive terminal and a negative terminal;
- at least one cell disposed within the housing and including at least one positive plate and at least one negative plate connected to the positive terminal and negative terminal, respectively;
- and
- an acidic electrolytic solution filling a volume between the positive and negative plates;
- wherein the at least one positive plate further includes
- a carbon foam current collector including a network of pores, and
- a chemically active material disposed on the carbon foam current collector such that the chemically active material penetrates the network of pores.
