Abstract
A conductive composite material, a method of preparing the same, and a secondary battery including the same. The conductive composite material may increase the proportion of an active material when forming an electrode by chemically bonding a conductive material and a binder to each other. A method of preparing the conductive composite material comprises ionizing carbon-based particles in a predetermined polarity, ionizing PTFE particles in a polarity different from that of the carbon-based particles, and chemically bonding the ionized carbon-based particles and the ionized PTFE particles, which are ionized in different polarities, to each other.
