Electrode, method of manufacturing the same, and rechargeable lithium battery including the same

A method of manufacturing an electrode for a rechargeable lithium battery, the method comprising:

• forming a first active material layer on an electrode current collector;
• and
• forming a second active material layer on the first active material layer,
• wherein forming the first active material layer comprises forming a first active material and a first composite conductive material, and
• wherein forming the second active material layer comprises forming a second active material and a second composite conductive material, and
• wherein forming the first composite conductive material comprises:
• introducing a first functional group onto a surface of the first carbon nanostructure;
• and
• mixing the functionalized first carbon nanostructure with a first polymer to prepare a first mixture,
• wherein forming the second composite conductive material comprises:
• introducing a second functional group onto a surface of the second carbon nanostructure;
• and
• mixing the functionalized second carbon nanostructure with a second polymer to prepare a second mixture,
• wherein the first polymer is different from the second polymer, and
• wherein an ionic conductivity of the second polymer is greater than an ionic conductivity of the first polymer.
