1. A method for manufacturing an electrode for a secondary battery, comprising the steps of:
(a) preparing a template foam;
(b) coating a graphene on the template foam;
(c) removing the template foam to form a graphene foam, wherein the template foam partially remains on an internal surface of the graphene foam; and
(d) growing a nanowire by using the template foam remaining on the internal surface of the graphene foam as a seed.
