Metals are the best example of a material where the electrons are free to move, since the valence electrons in a metal form an electron sea. Generally speaking, materials that are good phonon conductors are very bad electron conductors, and vice-versa. However, both are good heat conductors. Now, if you think of how electricity flows through a material, a voltage on one end of the material attracts electrons to it and the electrons form an electrical current as they rush toward the voltage.
