Abstract
Provided is a method of manufacturing a lithium secondary battery, the method including: preparing positive and negative metal foams having a plurality of first pores; controlling first pore sizes of the metal foams depending on an application; filling the first pores with a slurry obtained by mixing a positive electrode active material or a negative electrode active material, a binder, a conductive material, and an organic solvent; heat-treating the metal foams to form second pores having a size smaller than those of the first pores. The first pore size of the metal foam can be controlled, so that a high capacity and high output battery can be manufactured depending on the usage.

A method of making a lithium secondary battery, the method comprising:
- preparing positive and negative metal foams having a plurality of first pores;
- controlling first pore sizes of the metal foams depending on an application;
- filling the first pores with a slurry obtained by mixing a positive electrode active material or a negative electrode active material, a binder, a conductive material, and an organic solvent;
- heat-treating the metal foams filled with the slurry to then remove the organic solvent, fix the positive electrode active material or the negative electrode active material, the binder, and the conductive material to inner sidewalls of the first pores to thus form second pores having a size smaller than those of the first pores;
- and
- sequentially laminating a separator and a negative electrode on both surfaces or one surface of a positive electrode of the metal foams into which an electrolyte is permeated.
